Daichi Ishizaki is a male student of Class 1-C at Advanced Nurturing High School who later advances to Class 2-C.

He is portrayed as a problem child with a history of fighting and delinquent behavior since middle school, but over time grows into a semi-regular supporting character in Classroom of the Elite.

At first, he opposes Kakeru Ryuen’s rule within the class alongside Albert Yamada.

After being defeated and overwhelmed by Ryuen, he submits to him and becomes a loyal follower, often treated as a servant and harshly overworked.

Despite frequently being criticized as “useless” by Ryuen, Ishizaki acknowledges Ryuen’s strength and sees him as a legitimate leader.

When Ryuen is defeated by Kiyotaka Ayanokōji and announces his intention to withdraw from school, Ishizaki and Albert stake their own expulsions to prevent Ryuen from being forced out.

Following the incident on the rooftop, Ishizaki drastically changes his attitude toward Kiyotaka Ayanokōji.

He begins to speak to him cheerfully and casually, as if to a close friend, and steadily builds a more friendly relationship with him.

Ishizaki is quick-tempered, rough, and always ready to pick a fight.

He behaves in an arrogant and domineering way, slacks off in class, and has a generally irresponsible attitude.

His manners toward students of other classes are especially bad, causing many to avoid him just as they avoid Ryuen.

However, beneath the surface he is straightforward, honest at heart, and surprisingly dutiful.

He is the type who “gets it” once spoken to properly.

Even after previously clashing with people, he is willing to cooperate once they reconcile, as seen with Kiyotaka Ayanokōji and Teruhiko Yukimura.

After having framed Ken Sudo earlier, Ishizaki later steps in between Sudo and another delinquent, telling the aggressor off when Sudo is being harassed.

This shows his strong sense of obligation and loyalty to people he has come to respect or feel responsible toward.

Even so, his top priority is always Ryuen’s orders.

He participates in morally questionable or outright cruel schemes toward other students—such as the incident with Sudo’s violence case, the rooftop torture of Kei Karuizawa, or spiking a student from Honami Ichinose’s class with laxatives—without hesitation when instructed by Ryuen.

He does feel a certain degree of guilt each time and is not completely numb to the harm he causes.

Still, he clearly separates his personal feelings from “business,” obeying Ryuen’s commands above his own conscience.

He also has very typical teenage-boy sides.

He gets flustered around Honami Ichinose, refuses Hiyori Shiina’s room visit because he has tissues scattered everywhere, and reacts nervously to Mio Ibuki and other girls, showing he is very much a normal high school boy underneath his delinquent exterior.

Early Depiction

Ishizaki is first introduced in volume 2.

Initially, he appears as “Ryuen’s underling No. 1,” a thug-like henchman without much depth, but his repeated appearances slowly turn him into a semi-regular character with more nuance.

On Ryuen’s orders in volume 2, Ishizaki provokes Ken Sudo, intentionally gets punched, and then reports the incident as a serious case of violence to the school, posing as the victim.

However, Airi Sakura coincidentally witnesses the setup and becomes an important witness against him.

The disciplinary hearing gets extended thanks to Suzune Horikita’s efforts and the submission of evidence by Sakura.

The next day, Ishizaki is tricked by Kiyotaka Ayanokōji and Honami Ichinose, who bluff about there being surveillance camera footage, and he withdraws his accusation against Sudo.

In the anime adaptation, Ryuen has Albert punish Ishizaki physically for his mishandling of the case.

This emphasizes the harsh hierarchy within Ryuen’s faction and the physical intimidation used to keep his subordinates in line.

Rooftop Incident and Its Aftermath

In volume 7, Ishizaki goes to the rooftop with Ryuen to lure out Kei Karuizawa in order to expose the hidden mastermind of Class D.

Following Ryuen’s instructions, he repeatedly pours buckets of cold water over Karuizawa, triggering painful memories of the bullying in her past to force her to reveal the mastermind’s name.

When Kiyotaka Ayanokōji arrives alone on the rooftop to rescue Karuizawa, Ishizaki charges in to attack him.

He is, however, effortlessly dealt with and knocked out, and Albert is similarly defeated in seconds.

By the time Ishizaki wakes up, the confrontation is already over.

Ryuen, taking responsibility for the failure, tries to withdraw from school, but Ishizaki and Albert stop him by staking their own expulsion as collateral so that Ryuen can stay.

In volume 7.5, following Kiyotaka’s advice, Ishizaki and the others create a cover story.

They claim that internal fighting within Class C led to Ishizaki’s group narrowly defeating Ryuen, forcing him to step down as leader, and they use this narrative to smooth things over.

Ishizaki himself is unhappy with this arrangement and the idea of Ryuen being sidelined.

He waits for the day Ryuen will return to the front lines and lead the class once again.

Mixed Training Camp and Building Bridges

In volume 8, during the mixed training camp, Ishizaki and Albert end up in the same group as Kiyotaka Ayanokōji.

Although Ishizaki keeps up a tough front, whenever he meets Kiyotaka’s eyes he becomes visibly nervous, remembering how easily he was beaten on the rooftop.

Frustrated and stressed, he is initially uncooperative and acts like a burden to the group.

Masayoshi Hashimoto eventually scolds him and convinces him to talk things out, leading to a reconciliation with Teruhiko Yukimura.

From that point, Ishizaki starts cooperating more with the group.

This marks one of the earliest signs that he is capable of growth beyond simply being Ryuen’s muscle.

Class Vote and Deepening Ties with Ayanokōji

In volume 10, a special class vote puts Ryuen at high risk of expulsion.

Desperate, Ishizaki and Mio Ibuki visit Kiyotaka’s room to ask for advice on how to save their leader.

In the end, they collaborate with Honami Ichinose and manage to prevent Ryuen’s expulsion.

Because Kiyotaka acts as the mediator and helps arrange this solution, Ishizaki develops strong trust and gratitude toward him.

From this point on, Ishizaki’s attitude toward Kiyotaka changes drastically.

He no longer sees him only as a frightening opponent, but also as someone reliable and even friend-like.

Return of Ryuen and Class C’s Resurgence

In volume 11, during the Selected Events Exam, Ishizaki asks Ryuen to return to active leadership so they can aim for Class A again.

Responding to this, Ryuen reappears on the stage of class politics.

Under Ryuen’s renewed leadership, Ishizaki helps carry out sabotage operations against Class B.

Their strategy succeeds, resulting in a decisive victory over Class B and allowing their class to climb back up to Class C from the second year.

In volume 11.5, during spring break, Ishizaki runs into Kiyotaka again.

He enthusiastically shares his “strongest strategy,” insisting that if Ryuen and Kiyotaka joined forces, they would be unbeatable, and he even invites Kiyotaka to transfer into his class.

Kiyotaka, however, prefers to remain Ryuen’s rival rather than his ally and declines the offer.

Ishizaki’s reaction is more comedic than hostile, highlighting how their relationship has become more friendly and relaxed.

Volume 2: Deserted Island and Recruiting Ayanokōji

In the second-year volume 2, Ishizaki, together with Hiyori Shiina and Albert, once again tries to recruit Kiyotaka into their class.

As part of this effort, he proposes cooperating during the uninhabited island survival exam, hoping that shared interests will bring them closer.

While still loyal to Ryuen, Ishizaki shows initiative by approaching Kiyotaka directly.

This reinforces the image of him as a bridge between Ryuen’s faction and Kiyotaka.

Volume 3: Looking Out for Isolated Classmates

In volume 3, during the exam itself, Ishizaki notices Takeko Nishino becoming isolated and distant from the rest of the class.

Despite his rough personality, he cannot bring himself to simply ignore her.

He ends up grouping with Nishino instead of leaving her alone.

This small act shows his growing empathy and an increasing sense of responsibility toward his classmates.

Volume 4: Alliance and Battle on the Island

In the second half of volume 4, Ishizaki’s group merges with Hiyori Shiina’s group to form a large collaborative unit during the extended survival exam.

By the 13th day, they regroup under Ryuen and take part in a decisive confrontation.

Ishizaki and Albert support Ryuen by attacking from behind and restraining another delinquent, Housen, contributing directly to his defeat.

Ryuen acknowledges their efforts and offers words of praise, a rare but meaningful gesture that further strengthens Ishizaki’s loyalty.

Volume 5: Full Consensus Special Exam and Conflict Over Ibuki

In volume 5’s unanimous consent special exam, the class must decide on a student to be expelled.

Ishizaki worries that Mio Ibuki might become the target of the girls’ vote and considers protecting her.

However, Takeko Nishino warns him that half-hearted camaraderie will only create confusion and make things worse.

This forces Ishizaki to confront the tension between emotional loyalty and cold strategic thinking.

Volume 6–7: Apology to Karuizawa and Mending the Past

In volume 6 of the second-year arc, Ishizaki reunites with Kei Karuizawa for the first time since the rooftop incident.

Accompanied by Albert, he formally apologizes to her for his role in her torture and humiliation.

By the time of volume 7’s cultural festival, his relationship with Karuizawa has somewhat improved.

While things are not completely erased, she at least acknowledges the sincerity of his apology and no longer sees him as just an irredeemable tormentor.

Ishizaki’s academic ability is low at D- (21), making him one of the weaker students in terms of study.

He is not suited to complex theorizing or intense intellectual work and relies heavily on others for strategy and planning.

His physical stats are much better, with a C+ (60) in physical ability.

He is strong, sturdy, and able to act as a front-line fighter or enforcer, which is why Ryuen often uses him in confrontations and physical intimidation.

His thinking and adaptability sit at C (52), meaning he is not an idiot but tends to be easily manipulated, as when he falls for Ayanokōji’s bluff about surveillance cameras.

His social contribution score, D+ (40), reflects his rough outward behavior and delinquent history, though his actions show potential for growth in cooperation and loyalty.

Overall, Ishizaki’s total rating is C- (44), slightly below average.

He compensates for his insufficient academics and social rating with strong physical ability, simple honesty, and unwavering loyalty to those he respects.

Kakeru Ryuen

Ryuen is Ishizaki’s leader and the person he respects the most in class.

At the start of high school, Ishizaki resents Ryuen’s high-handed, oppressive style and the way he abuses his subordinates, and they even come to blows several times.

Over time, however, Ishizaki becomes deeply influenced by Ryuen’s strategic thinking, ruthless decisiveness, and fighting spirit.

He gradually comes to admire Ryuen’s strength and begins to revere him, probably having the strongest loyalty to Ryuen in the entire class.

Ishizaki obeys Ryuen’s orders even when they conflict with his personal morals.

He goes as far as wagering his own expulsion to protect Ryuen from being forced out of school.

Mio Ibuki

Ibuki is Ishizaki’s classmate and partner in many of Ryuen’s schemes and hardships.

Having gone through numerous difficult situations together, he feels a stronger sense of comradeship with her than with most other classmates.

Their relationship resembles that of “bad friends” who bicker but still trust one another.

Ibuki acts annoyed by him, but she does not truly dislike Ishizaki and accepts him as a companion.

Albert Yamada

Albert and Ishizaki also share a long history of working together under Ryuen.

They see each other as genuine friends, not just fellow henchmen.

Although Albert speaks little and is often quiet, he understands Japanese, so communication between them is not an issue.

Their cooperation in fights and operations, such as restraining enemies during exams, showcases how well they function as a pair.

Hiyori Shiina

Hiyori Shiina is a classmate whom Ryuen values for her intelligence and calm judgment.

Because she is favored by Ryuen, Ishizaki initially treated her with polite speech and a clear sense of hierarchy, acknowledging her higher status in the class structure.

Over time, this rigid hierarchy softens, and they become more casually friendly.

Ishizaki often relies on Hiyori’s advice and knowledge, showing that he respects her abilities and trusts her.

Ken Sudo

Ken Sudo was originally a target framed by Ishizaki in volume 2.

Ishizaki’s provocation and false testimony nearly resulted in Sudo’s expulsion and created a tense, hostile relationship between them.

Later, on the uninhabited island, Ishizaki notices Sudo worrying about his injured teammate Kyougo Komiya.

In a separate incident, when another delinquent, Housen, treats Sudo roughly, Ishizaki steps in and warns him off, suggesting that Ishizaki has decided to let bygones be bygones.

By then, both of them seem to have moved past the earlier incident.

They are not close friends, but there is a mutual understanding and a sense that old grudges have been laid to rest.

Kei Karuizawa

Kei Karuizawa is one of Ishizaki’s victims in the rooftop torture incident.

Following Ryuen’s orders, Ishizaki repeatedly poured cold water on her and helped break her psychologically to draw out information.

The memory of what he did leaves Ishizaki with lingering guilt.

When he encounters Karuizawa again in the second-year arc volume 6, he formally apologizes to her together with Albert.

Though Karuizawa cannot simply forget the past, Ishizaki’s sincerity leads to a partial reconciliation.

By the time of the cultural festival, their relationship has noticeably improved, showing Ishizaki’s capacity for remorse and atonement.

Kiyotaka Ayanokōji

Initially, Ishizaki and Kiyotaka are on opposing sides.

Their relationship begins with the provoked violence case against Ken Sudo and escalates further during the rooftop incident, where Ishizaki is defeated in seconds.

However, during the class vote crisis that threatens Ryuen, Kiyotaka becomes the key figure in saving Ryuen from expulsion.

After receiving vital help from Kiyotaka, Ishizaki’s attitude changes completely.

He is one of the few people who know firsthand how overwhelmingly strong Kiyotaka is in a fight.

This knowledge, combined with Kiyotaka’s calm support during the vote, makes Ishizaki respect him deeply and accept him as a friend.

Later, Ishizaki even tries to recruit Kiyotaka into Ryuen’s class, excited by the idea that “Ryuen and Ayanokōji together would be invincible.”

Kiyotaka refuses, but their dynamic stays friendly, with Ishizaki treating him as a trusted ally despite remaining in different classes.

Takeko Nishino

Nishino is a classmate who tends to be withdrawn and somewhat isolated.

During the second-year island exam, Ishizaki cannot ignore her isolation and chooses to group with her instead of leaving her alone.

She later warns him about the danger of half-hearted camaraderie when he considers protecting Ibuki in the unanimous vote exam.

This frank, pragmatic advice influences Ishizaki’s understanding of what it means to be a “teammate” in the harsh, competitive environment of the school.

Other Notable Connections

Ishizaki has brief but meaningful interactions with several other characters.

He learns from Masayoshi Hashimoto’s scolding during the mixed training camp, which helps him reconcile with Teruhiko Yukimura and become more cooperative.

He is also visibly shy around Honami Ichinose and other girls, which humanizes him beyond the usual delinquent stereotype.

His interactions with multiple students across different classes illustrate his gradual transition from a one-note thug to a more complex and approachable character.
