A Certain Magical Index is a Japanese light novel series written by Kazuma Kamachi and illustrated by Kiyotaka Haimura, serving as the foundation for a wide array of derivative and media-mix works. Published by Dengeki Bunko since April 2004, this popular franchise is often referred to as the "Toaru Series" when including its numerous spin-offs. It blends science fiction and fantasy, depicting a dynamic world where a technologically advanced "Science Side" and an occult-driven "Magic Side" clash.
Works Background
The series came to life when Kazuma Kamachi's submission, though failing the third selection round of the 9th Dengeki Novel Grand Prize, captured the attention of his editor, Kazuma Miki. After a year of collaborative prototyping, a story about a nun girl and a boy with a mysterious right arm became the genesis of "A Certain Magical Index."
Kamachi's initial inspiration stemmed from a curiosity about real-life historical magicians and rituals, moving beyond typical RPG wizard tropes. He delved deep into these topics using search engines. The world-building expanded significantly from this point, starting with the character Index Librorum Prohibitorum, around whom magic and KAMIJO TOUMA were developed, eventually giving rise to the contrasting setting of Academy City.
Structure
The narrative is primarily written in the third person, often employing a "god's-eye view" that shifts between different character perspectives, though it largely centers on the protagonist. As the story evolves and more characters are introduced, it gradually transforms into a compelling ensemble drama.
Each volume features distinct keywords and themes, leading to noticeable shifts in atmosphere and style. Kamachi himself has mentioned setting experimental challenges for each volume, constantly exploring new narrative techniques and literary skills.
The series is broadly divided into major arcs: volumes 7-11 cover the "Roman Orthodox Church Arc," while volumes 12-22 detail the "God's Right Seat Arc." Following a significant turning point in the "God's Right Seat Arc," the numbering was reset after volume 22, launching the new 23-volume series, A Certain Magical Index: New Testament. In February 2020, the numbering was reset once more for the ongoing series, A Certain Magical Index: Genesis Testament.
Style and Features
The series often draws comparisons to Shonen Manga, with its core revolving around the protagonist battling to overcome formidable challenges. Kamachi describes it as a story where "the protagonist directly confronts magicians or espers burdened with complex problems," and KAMIJO TOUMA's unwavering resolve in these fights forms the backbone of the narrative.
A distinctive feature is the frequent use of unique readings for Kanji (phonetic guides, primarily in Katakana) for in-universe terminology and character aliases. Kamachi also notes that explanations of the world's intricate setting frequently appear within the narration or dialogue, leading to dramatic shifts in character actions from scene to scene.
The cast of characters is incredibly diverse, with well over 100 named individuals and designs, including a substantial number of heroines. Kamachi excels at crafting new stories centered around new heroines and characters, asserting that he "throws all kinds of heroines into one series, leaving no blind spots." While early volumes rotated the central heroine to maintain reader engagement, the focus gradually shifted towards world-building around volume 9.
Kamachi aims for a narrative where stories are built around characters designated as protagonists. This means that focusing on any character within the series can generate a unique story centered on them, making everyone a potential protagonist. This approach explains the increasing number of main and secondary main characters as the plot unfolds.
Many characters possess distinctive speech patterns and verbal tics, a clever narrative device that allows readers to instantly identify who is speaking without constant descriptive interjections in dialogue.
Achievements and Recognition
As of June 2019, the original light novel series had cumulatively sold over 18 million copies, and by July of the same year, the entire "Toaru Series" had surpassed 31 million copies in print. Notably, this series was the first in Dengeki Bunko's history to have its original novel volumes exceed 10 million copies sold.
Upon the release of its first volume, the series became an instant smash hit, described by its editor as "selling like crazy" and an "unprecedented feat for an unknown rookie author," necessitating an immediate reprint shortly after its launch.

KAMIJO TOUMA interacts with Asuka Kasei, the student council president of the host school, and Akikawa Mie, who looks after her, and also works alongside Kamisato, who helps the student council. Although KAMIJO TOUMA cooperates with Kamisato's proposed plan against Saku, Kamisato's offer turns out to be a trap, and KAMIJO TOUMA is attacked by Kamisato's faction. However, Saku intervenes, confronting Kamisato and rousing Accelerator to rescue KAMIJO TOUMA. Saku realizes that KAMIJO TOUMA's power is essential to awaken Kamisato and forms an alliance with him.
Akikawa notices a change in Asuka Kasei's behavior and confides in KAMIJO TOUMA. When KAMIJO TOUMA and Saku learn that the rumor about the incinerator is Kamisato's doing, they suspect the real student council president is trapped there and rush to stop students from lighting it. Finding nothing inside, KAMIJO TOUMA disappoints the students and becomes isolated. When Kamisato appears, Saku and Akikawa are furious, but Kamisato denies knowing about the student council president, claiming the rumor had another purpose. As the four are confused, Asuka Kasei appears, severing Kamisato's "World Rejecter" as Kihara Yuiitsu reveals her true identity.
With "World Rejecter" in hand, Yuiitsu battles Saku's faction, who seek to reclaim Kamisato's right hand, and KAMIJO TOUMA. Despite Saku's "External Offering" providing ample attacks and "World Rejecter" being ineffective, they fight well until a Magic God created by Yuiitsu obliterates them. KAMIJO TOUMA and Saku are rescued by MISAKA MIKOTO, but Yuiitsu's pursuit scatters them. MISAKA MIKOTO, alone and falling into a building, contacts "Anti-Magic System Driving Armor." Yuiitsu's focus shifts to MISAKA MIKOTO, fearing her touching the memento, giving KAMIJO TOUMA and Saku a chance. However, their hesitation creates an opening, and KAMIJO TOUMA is captured by Yuiitsu. Witnessing this, MISAKA MIKOTO impulsively uses the "Anti-Magic System Driving Armor," fearing KAMIJO TOUMA's loss, and vaporizes Yuiitsu's physical body.
Afterward, MISAKA MIKOTO wanders the night, trembling with the knowledge of a new world beyond the "Anti-Magic System Driving Armor." However, a concerned security guard makes her realize she's bleeding from her nose, and she puzzles over the reason. Meanwhile, Kamisato, still revered by his faction's girls despite losing "World Rejecter," realizes their affection was unrelated to his power. Embracing this newfound understanding, he prepares for a final confrontation to return to their normal lives with them.

New Testament Volume 18:
On December 11th, Motoharu Tsuchimikado and Furean attempt to escape Academy City, but Motoharu Tsuchimikado's sister, Maika Tsuchimikado, is afflicted by Aleister Crowley's magic. To resolve the situation, KAMIJO TOUMA, alongside the Tsuchimikado siblings, Index Librorum Prohibitorum, Othinus, and Karamaru Furean, infiltrate the "Windowless Building," the headquarters of Academy City's Board Chairman. There, following an invitation from a woman claiming to be Mina Mathers, KAMIJO TOUMA experiences the trajectory of "human" Aleister Crowley. He witnesses the death of Aleister's beloved daughter, Lilith—the cause of his hatred for magic—and glimpses the arrow containing the previous Imagine Breaker during the "Battle of Blythe Road." Guided by Mina, KAMIJO TOUMA finally confronts Aleister, learning that Academy City was built for him. He struggles against Aiwass, summoned during their battle, but with the help of those around him, he manages to temporarily dissipate Aiwass. KAMIJO TOUMA finally defeats Aleister.
After KAMIJO TOUMA's victory, Laura Stuart appears in the Windowless Building. She reveals her true identity as Coronzon, possessing Aleister's second daughter, "Laura," and, to fulfill a past "contract," kills Aleister with the Sword of Damocles. However, immediately after, "1.083 billion and 9,2867" possibilities hidden within Aleister are unleashed, declaring war on Coronzon. Countless Aleister forces swiftly begin to conquer England and its allied nations. Ultimately, one of these possibilities, a feminized Aleister, makes contact with KAMIJO TOUMA.
Coronzon Arc (Volumes 19-22 Reverse)
New Testament Volume 19:
Aleister Crowley launches the Windowless Building, with Coronzon aboard, into space. Aiwass then appears, allowing Mina to escape the building back to Earth before engaging Coronzon in battle in space. To counter Coronzon's threat, who manipulates the "A.O. Francisca" (a medium based on Karamaru Furean) from space to seize control of Academy City, KAMIJO TOUMA and the feminized Aleister begin to work together.
Meanwhile, Hamazura Shiage inexplicably finds himself clad in an unidentified protective suit, the "Processor Suit," and targeted by Accelerator and another figure in a similar suit, the mysterious "A.O. Francisca." He discovers a mysterious baby named Lilith and reunites with Takitsubo, but Lilith suddenly develops a fever. At the hospital he takes her to, he finds medical databases inaccessible, realizing his Processor Suit is the cause. The suit is actually the Academy City's integrated database, the "Bank." "A.O. Francisca," one of Coronzon's mediums, had stolen the Processor Suit to take over Academy City and put a spare suit on Hamazura as a decoy. However, an unintended SIM conflict occurred between the suits, and the spare suit (Hamazura) became a target. Accelerator, who had quickly noticed this anomaly, pursues "his own ability-reproducing suit" and Francisca—the source of the commotion—and encounters Mina, engaging her in battle. Later, he suggests to Hamazura, who mistakenly believed Lilith was the anomaly's core, that their understandings differ.
Hamazura, cornered by Francisca, is saved by Lilith, who exhibits a mysterious power. Through the wooden doll she controls, she introduces herself as "Nuit Ma Asanour Hecate Sappho Isabella Lilith" and speaks to her absent "father," Aleister Crowley. Later, she is reunited with her father, and Aleister holds his beloved daughter in his arms for the first time in a century.
Mina rescues the automatically writing Index Librorum Prohibitorum who appeared as an enemy before KAMIJO TOUMA, while Aleister saves Furean, who had been made Coronzon's medium. It seems the threats surrounding Academy City have been momentarily averted. However, Coronzon, having defeated Aiwass, then causes the Windowless Building, which was moving in outer space, to fall towards Academy City. This, however, was a trap set by Aiwass and Aleister; the Windowless Building actually crashed into the "New World."
Aleister Crowley then declares the "Freezing of Academy City" and the "Recapture of his other daughter (Laura), who was made a medium," targeting Coronzon, who had returned from the New World.

After the battle, Kaori Kanzaki tries to persuade the girl to leave the island but, understanding the deep-rooted problems of the island and the girl's stance, leaves without capturing her.
Episode 3: "The True Meaning of Environmental Protection: Rulic Letters": Ordered to prevent destructive magical activities, Kaori Kanzaki and her team go to a large ironworks in an industrial area of a Danish port city. While investigating traces of enemy runes, explosions suddenly erupt in various locations. Kaori Kanzaki manages to prevent the worst, then deduces the enemy magician, Reasick's location from the magic's mechanism, catches up to him, and captures him. Hearing Reasick's self-serving claims, Kaori Kanzaki quietly seethes with anger and defeats him.
Episode 4: "Various Lives: Alfarr": Kaori Kanzaki is tasked with reclaiming the Brick Wharf, a crucial Anglican Church stronghold in northern Scotland, which has been occupied by Alfarr.

Episode 5: "Oceanic Prison: Naglfar": One of the submarine-type giant facilities for housing and transporting dangerous enemy magicians worldwide, the Oceanic Prison, goes out of control while sailing in the Indian Ocean. Kaori Kanzaki and her team disregard orders from high command for a massacre solution and investigate to peacefully regain control, eventually discovering that the "Naglfar" legend is being used to seize control. Kaori Kanzaki and her team directly board the Oceanic Prison to dispel the magic, but a female colleague magician, "Veidar's Shoe Woman," appears, intending to carry out the high command's orders. Kaori Kanzaki engages her in an offshore battle to stop her, sees through the weakness of her magical artifact, and defeats her. She then warns the Oceanic Prison's inmates, intimidating them into surrender with her sheer presence.
Episode 6: "The Best Moment: Bifrost": Kaori Kanzaki, receiving news of the tracked magician Orenz Torais's stronghold, heads to the location. Upon infiltration, she encounters Leivinia and Mark, but due to the peculiar nature of the transport container they are in, they are forced to a temporary ceasefire. Kaori Kanzaki and Leivinia, whose personalities clash, find their animosity and irritation growing despite Mark's attempts to mediate. Upon the container's arrival, the two, reaching their breaking point, engage in a fierce battle, casually defeating Orenz, who was waiting for them, as collateral damage.
Episode 7: "The Destination of Salvation: Gungnir": Investigating a series of attacks on five major Norse Mythology-affiliated magic societies by a mysterious culprit, Kaori Kanzaki and her team deduce the possibility of a Saint's involvement from the crime scenes. They then preemptively ambush the next predicted attack site, encountering Brynhildr Eiktobel, a Saint and Valkyrie. Kaori Kanzaki and Brynhildr clash, but Brynhildr, realizing her disadvantage, escapes. Afterward, Kaori Kanzaki and her team question the magician victims, asking one, Seturua, about Brynhildr.

Episode 8: "The One Who Delivers the Hidden Script: Valkyrie": Kaori Kanzaki arrives at the secluded abandoned factory where Brynhildr is, engaging her in a fierce battle. However, she struggles against "Gungnir" and the "Last Rune," forced to retreat and regroup. A communication from the Jeans Shop Owner reveals the existence of Seilie Flatley, a boy who seems to be Brynhildr's motive. Despite Brynhildr interfering with the communication and provocatively interrupting, Kaori Kanzaki tries to persuade her of the futility of her actions based on her own experiences, but to no avail. The two begin their final confrontation, with Kaori Kanzaki ultimately emerging victorious. Later, Kaori Kanzaki and her team discover the plot of Richard's faction, who are targeting Seilie, and head to the location to thwart their scheme.

However, their communication with the examiner is swapped, and the exam is exploited to obtain a "Free Pass" that bypasses the magical locks managed by "Necessarius."

Official Parody Spin-offs
These works are all official parody gag stories, with no direct chronological or story connection to the main series. They often contain strong meta-fictional elements, with characters referencing the series' settings or even the series itself.
A Certain School Index Librorum Prohibitorum:
This parody spin-off re-imagines the characters in a "school life" setting, incorporating numerous elements from adventure games. It humorously features Accelerator disguised as Suzushina Yuriko, a character KAMIJO TOUMA idly imagined in volume 6. The characters and descriptions are based on the setting at the time of volume 6's publication.
KAMIJO TOUMA wakes up to find everyone around him acting strangely. He learns that for some reason, Academy City has been subjected to "rules," and everyone must play a role as a character in a school life story. Various individuals, from those acting normally or with somewhat related roles to those forced into exaggerated personas, gather around KAMIJO TOUMA, leading to chaotic events.
A Certain Magical Index? A Certain March Gift Exchange & A Certain March 201st Volume:
These parody spin-offs revolve around White Day and a graduation ceremony. As works published in "Dengeki BUNKOYOMI" were themed according to their respective months, these stories align with March. While not strictly connected to the main story, they are loosely set several months to years after, with any intervening events summarily dismissed as "various things happened." The characters and descriptions align with the period around volume 11's publication.
A Certain March Gift Exchange: This White Day-themed parody highlights KAMIJO TOUMA's propensity for attracting romantic flags with women.
On March 14th, KAMIJO TOUMA, spending his day as usual, is inexplicably demanded "Valentine's Day returns" by various women around him, with no recollection of giving anything. It's eventually revealed that a month prior, convinced he "wouldn't get any chocolates anyway," he got drunk and, in a fit of delusion, wandered around the world, making countless women fall for him, all while blackout drunk. Plagued by these unexpected consequences of his unconscious actions, KAMIJO TOUMA laments his misfortune.
A Certain March 201st Volume: This graduation-themed parody plays on the series' extensive volume count, exploring graduation scenarios that are typically not featured in the main story.
In March, KAMIJO TOUMA and his fellow third-year students celebrate their graduation, reflecting on their long school days. After the ceremony, KAMIJO TOUMA wonders about his post-graduation path. He is immediately bombarded with conflicting recruitment offers—from the "Necessarius," to becoming a "Judgment" officer, and various other individuals—leaving him utterly confused.
I Hate the First Episode of "A Certain Magical Index"!! Or I Hate the Final Episode!!:
As the title suggests, this parody spin-off focuses on "imaginary first or final episodes." "Dengeki h&p" typically divides into "h (hajimari/beginning) part" for "I Hate the First Episode" and "p (period) part" for "I Hate the Final Episode." However, this work is titled "? (hatena/question) part," intentionally ambiguous. Within the story, characters try to deduce if it's the first or final episode. This piece is the most meta of the parody spin-offs, featuring an utterly chaotic plot. The characters and descriptions are based on the setting around volume 14's publication.
On July 19th, KAMIJO TOUMA and MISAKA MIKOTO confront each other on a railway bridge in the 7th District, attempting to recreate the scene from Volume 1. However, Kaori Kanzaki suddenly intervenes, suggesting that this might actually be the world of the final volume, "July 19th, one year after Volume 1." As MISAKA MIKOTO and Kaori Kanzaki unleash a fierce battle, raging about the lack of proper screentime for their characters, KAMIJO TOUMA systematically tries to determine if this world is truly the first or final volume.
Other

This preview short story for Volume 6, titled "A certain prophecy 'INDEX'" on Kiyotaka Haimura's official website, contains strong meta-elements, even referencing the story's development and the novel's release date.

Organizations and Groups
British Puritan Church: This is a faction of Christianity. It encompasses various groups, including the combat organization "Necessarius," the Amakusa-style Remix Church, and the Agnes Squad, with many magicians belonging to it.
Roman Orthodox Church: This is the largest Christian denomination, a massive force of 2 billion followers led by the Pope. Beyond its numerical strength and historical magical artifacts, it harbors its deepest and true highest organization, known as the "God's Right Seat."
The world of "A Certain Magical Index" initially appears similar to our reality but is imbued with magic and superpowers. This creates two dominant factions: the "Science Side," focused on scientific technology, and the "Magic Side," rooted in magical practices.
Science Side
Academy City is a collective of scientific organizations. In a broader sense, it refers to modern society as a whole that utilizes scientific technology, but in practice, the term "Science Side" largely denotes Academy City itself, as outside areas have only shallow involvement. Unlike the Magic Side, the Science Side has no other organizations equal to Academy City, which effectively reigns as its dominant stronghold.
Academy City is a fully independent educational and research institution located in western Tokyo. It possesses advanced scientific technology, decades ahead of the outside world. It conducts scientific research on superpowers, creating Espers through brain development. Beyond Esper abilities, it holds various futuristic over-technologies and next-generation weapons. Most ordinary residents of Academy City are unaware of magic's existence, but the upper echelons and parts of the dark side, including the Board Chairman Aleister Crowley, are aware of the Magic Side and maintain diplomatic relations with it.
Magic Side
The Magic Side is a collection of various organizations, including magical groups and magic departments operated by religious organizations, all operating in secret. Since magic itself is generally kept hidden from the public, its existence is mostly unknown to the Science Side and general society.
Existing in the shadows of the world since ancient times when magic first emerged, the Magic Side possesses a rich history. In contrast to the Science Side, which is dominated by Academy City, the Magic Side consists of multiple influential organizations with opposing goals and agendas, far from being unified. In fact, conflicts within the Magic Side are common, such as clashes between various Christian denominations or between Christian factions and magical societies. Moreover, due to magicians' unique beliefs, many prioritize personal matters over organizational loyalty, and some operate independently.
Unlike the Science Side and general society, most individuals on the Magic Side do not live conventional lifestyles (e.g., attending school or working) but pursue their own unique objectives. While Magic Side individuals use scientific technology for essential daily needs (like mobile phones or airplanes), they tend to avoid or dislike scientific norms, ideologies, and Academy City's advanced technology. Some even struggle with basic scientific devices.
Relationship Between the Two Sides
The Science Side and Magic Side are fundamentally incompatible and often in conflict. Technical information regarding science and magic is monopolized by each side and considered mutually exclusive; research into the opposing side's technology or direct combat between the two sides is forbidden. Both sides have established boundaries and agreements to avoid encroaching on each other's territory, with penalties imposed on those who cross the line. However, as long as these agreements are upheld, their relationship remains relatively stable, without overt conflict. When common enemies or problems arise and their interests align, they sometimes cooperate, sharing information, etc. The balance of power is believed to be evenly maintained, partly due to the Magic Side's lack of a unified front.
Espers and Magic
In the world of this series, superpowers (Espers) and magic are distinctly separate entities. Esper abilities are "scientific" phenomena developed artificially by modifying brain structures, categorized into precise levels and types. In contrast, magic is an "occult" phenomenon generated using religious laws and traditions, existing in diverse systems based on rituals and methods. As seen by the restriction preventing Espers from using magic, the two are fundamentally incompatible.
World Structure and Concepts
As supernatural phenomena genuinely exist in this world, divine, high-tier beings such as Gods, angels, and spirits are real, as are other worlds like Heaven and Hell, believed to reside in "alternate phases" with different wavelengths, making them difficult to perceive. Concepts like souls also exist, and some mythological events are treated as historical facts. Yet, simultaneously, it is a world governed by scientific laws, so the Earth, universe, and DNA structure, of course, also exist.
General Side
This refers to general society and nations outside Academy City and the Magic Side. These societies enjoy modern life supported by scientific technology from Academy City, while also belonging to religions and indirectly involved in the Magic Side's power struggles, often unknowingly. Thus, they are the "others" who are influenced by both sides but deeply committed to neither.
Regarding nations, many do not recognize magic and are generally counted as part of the Science Side (e.g., the United States and Japan). However, in some cases (e.g., England and France), the core of the state is deeply involved with the Magic Side or explicitly recognizes its existence.
Other Differences from the Real World
Aside from the aforementioned, the world of the series is largely identical to the real world, though there are some differences in national systems and social conditions. In-universe history also sometimes features magical elements woven into historical events, notable figures connected to magic, or modern history subtly altered by Academy City's influence.
It is unclear what year the story takes place, but based on in-story descriptions and dialogue, it is presumed to be the early 21st century (e.g., Aleister Crowley is officially reported to have died in 1947, and the text mentions "already more than sixty years ago, official reports stated he had died").

Main Series Manga
The main series manga of A Certain Magical Index has been serialized in Square Enix's "Monthly Shonen Gangan" since the May 2007 issue. The artwork is by Chuya Kogino, following the original story by Kazuma Kamachi and character designs by Kiyotaka Haimura.
The story progression in the manga largely mirrors the light novel series. However, it's worth noting that content equivalent to original light novel volumes 2 and 4 has been omitted. The author mentioned in the afterword of manga Volume 2 that this was partly due to popular demand for MISAKA MIKOTO to appear earlier in the story.

Fujishoji (JFJ), a subsidiary of Fujishoji, has released Pachinko and Pachislot machines based on A Certain Magical Index. As of February 25, 2025, including A Certain Scientific Railgun, Fujishoji (though Index Librorum Prohibitorum machines are manufactured by JFJ, they are sold by Fujishoji) has introduced 6 Pachinko models and 3 Pachislot models.
*P A Certain Magical Index*: The 319-version from JFJ was released in November 2020, followed by the 129-version Light PREMIUM ver. in March 2022. The 319-version is a mid-spec machine with a jackpot probability of 1/319, while the Light PREMIUM ver. (1/129) has a lighter jackpot probability and added effects. Both are ST machines with a 100% rush (probability variation) entry rate, meaning a jackpot guarantees entry into ST mode. While primarily using footage from the A Certain Magical Index III anime, it also includes numerous newly animated scenes specifically for this machine.
*Smart Slot A Certain Magical Index*: Released by JFJ in November 2023, this is a Smart Slot machine. It increases payouts through a "Gensou Goroshi RUSH" (Imagine Breaker RUSH) AT (Assault Time) system managed by the number of medals. Like its Pachinko counterpart, the visuals are based on the anime but include new, original scenes not found in the anime or light novel (such as KAMIJO TOUMA VS Teitoku Kakine, MISAKA MIKOTO VS Teitoku Kakine, etc.).
*P A Certain Magical Index 2*: The 319-version from JFJ was released in January 2024 as the successor to *P A Certain Magical Index*. It features new effects, songs, and a revamped spec. While the previous model offered a stable 100% ST entry, this new version has a 70% ST entry rate. However, it introduces jackpots that allow for a larger payout at once, shifting from a stable to a more volatile output performance.
*P A Certain Magical Index 2 Light PREMIUM 2000 ver.*: This is the sweet spot version of *P A Certain Magical Index 2*, released in January 2024. It is the first machine in the series to feature a Lucky Trigger. While the normal jackpot probability is increased to 1/99, the ST entry and continuation rates are lower compared to the mid-spec version (ST entry rate 50%, continuation rate approx. 65%). However, approximately 11% of jackpots during right-side play trigger the "Strongest Domain" (Lucky Trigger), the machine's biggest feature, boosting the continuation rate from around 65% to approximately 91%, significantly increasing continuous payout potential. The visuals are based on the mid-spec version of Index 2 but include many new effects. For example, the "Dragon Strike" (Ryuuou no Ago) prediction, a highly anticipated effect for jackpots, and existing effects like "Spell Intercept" (Kyousei Eishou) prediction and "Railgun" (Choudenjigou) prediction have been revamped. In the custom mode, players can choose a "Saki Rorirori Mode" featuring Index Librorum Prohibitorum, Last Order, Komoe Tsukuyomi, Birdway, and Frenda. Each character has different activation conditions, not only indicating jackpot expectations but also notifying of ST jackpots. In the ST mode, "A Certain Magical Strongest Clash" (Heroes RUSH & Strongest Domain), in addition to "Index Librorum Prohibitorum Mode," "Railgun Mode," "Accelerator Mode," and "Heroine Mode," a new "Heroine Nap Mode" has been added. If the heroine wakes up, it's a jackpot, and players can choose from Index Librorum Prohibitorum, MISAKA MIKOTO, Lesser, Oriana Thomson, and Major Heart. Furthermore, the machine features an original song, "Real," sung by Yuka Iguchi, specially written for this model.
The series is featured in "Dengeki Bunko Recitation Tried It," a project where voice actors recite Dengeki Bunko novels. A recitation by Yuka Iguchi for A Certain Magical Index, lasting about 7 and a half minutes, was released on July 20, 2021.
