Sakura Heartrock

Sakura Heartrock originally serves the Ronishi Empire as a member of the emperor’s personal assassination corps.

Her missions include high-value targets such as Hime and later Maou.

At one point, Sakura is ordered to assassinate Hime.

She infiltrates Hime’s surroundings under a false identity, approaching her as a friend in order to get close enough to kill her.

Over time, Sakura and Hime genuinely become close friends.

Sakura develops real affection for Hime, which directly conflicts with her assassination orders.

When Sakura finally attempts to carry out her mission, she attacks Hime from behind.

However, she hesitates at the crucial moment and fails to deliver a fatal blow.

Because of that hesitation, Hime survives and counterattacks.

Sakura is defeated in this exchange and ends up at Hime’s mercy.

Hime realizes from Sakura’s expression when their eyes met during the attack that Sakura never truly wanted to kill her.

Respecting their past friendship, Hime chooses not to finish Sakura off and lets her live.

After failing to assassinate Hime, Sakura’s position in the Ronishi Empire collapses.

The subsequent mission to assassinate Maou is essentially a death sentence disguised as a final assignment.

Sakura infiltrates Maou’s castle to carry out this mission.

Instead of succeeding, she is captured and subjected to Torture Tortura’s “torture,” which in this case takes the comedic form of delicious ginger pork.

Unable to withstand the “torture,” Sakura confesses her true identity as an imperial assassin.

She also reveals her failed past mission involving Hime and her current hopeless situation within the Ronishi Empire.

Maou listens to Sakura’s story and sympathizes with her circumstances.

Rather than executing her, Maou shows mercy and arranges for her to be taken in by the Demon King’s Army.

Sakura is placed under Torture Tortura’s supervision as a trial recruit in the Demon King’s Army.

From then on, she affectionately calls Torture Tortura “senpai,” treating her as a senior colleague and mentor.

Although Sakura’s full debut as an active character happens from volume 7 of the series, her existence is foreshadowed much earlier.

In a flashback scene in the seventh “torture” segment collected in volume 1, Hime recalls a “friend who betrayed her,” and this person is later revealed to be Sakura.

This retroactive connection gives Sakura’s character a deeper emotional weight.

She is not just a new addition, but someone whose actions have quietly influenced Hime’s past and emotional world.

After joining the Demon King’s Army, Sakura becomes part of the broader ensemble of characters revolving around Maou, Hime, and Torture Tortura.

Her presence adds a layer of ex-assassin tension mixed with affectionate comedy and awkward sincerity.

Her jobs now include both combat-related duties and administrative tasks like report writing after “torture” sessions.

This contrast between her lethal training and mundane office work is often played for humor.

Sakura’s relationship with Hime is one of the emotional cores of her character.

They started as supposed friends formed under false pretenses, but that relationship gradually turned into something real.

During their first relationship, Sakura approached Hime purely as part of her mission.

Despite that, daily interactions, shared time, and mutual trust led Sakura to truly care for Hime.

When the time came for Sakura to strike, she could not fully commit to killing Hime.

This hesitation, born from genuine affection, cost her the success of the mission but saved her integrity as a person.

Hime, in turn, recognized Sakura’s inner conflict from her expression in the moment of attack.

Hime saw that Sakura did not truly wish to kill her, and her own feelings of friendship stopped her from delivering a finishing blow.

Much later, in Torture 126, Sakura and Hime finally meet again after all of this history.

They use a “circus performance”–style comedic “torture” session as a setting to talk honestly and draw out Hime’s true feelings.

That night, the two of them continue to talk until late, working through their shared past and misunderstandings.

The conversation helps to heal their emotional scars and rebuild trust.

In Torture 127, to celebrate their reconciliation, they go on a group outing to a ranch with their companions.

When Youki asks about the current state of their relationship, Hime and Sakura answer together, cheerfully declaring “Yes! We’re friends!”

From that point on, Sakura and Hime are not just ex-assassin and ex-target, but true friends.

Their bond becomes a genuine, mutual friendship built on honesty and shared experiences rather than deception.

Even within the comedic tone of the series, this friendship retains a sincere emotional resonance.

Sakura’s arc shows that even someone trained to kill can choose connection over duty.

Maou first encounters Sakura as a captured enemy assassin.

By all logic, Sakura’s attempt on Maou’s life should have led directly to her execution.

However, Maou is moved by Sakura’s story, particularly her failed mission involving Hime and the way her own empire abandoned her.

Seeing that she is more of a disposable pawn than a true enemy, Maou chooses to show compassion.

Instead of executing her, Maou arranges for Sakura to be placed under Torture Tortura’s supervision as a provisional member of the Demon King’s Army.

This effectively rescues her from the de facto death sentence she had been given.

Maou’s decision marks a turning point in Sakura’s life.

She gains a new home and a new purpose, no longer merely a tool of the Ronishi Empire.

Torture Tortura is Sakura’s direct superior after she joins the Demon King’s Army.

Sakura quickly comes to respect her and affectionately calls her “senpai,” highlighting a warm mentor-mentee dynamic.

Torture Tortura’s “tortures” are famously more like indulgent treats than actual torment, such as cooking delicious ginger pork.

Sakura, originally hardened as an assassin, is no match for this kind of temptation-based interrogation and easily opens up.

Under Torture Tortura’s guidance, Sakura adapts to life in the Demon King’s Army.

She participates in “torture” sessions, contributes as a subordinate, and slowly shifts from lethal asset to somewhat comedic colleague.

After every “torture” session, there is normally a requirement to write a detailed report.

However, during Sakura’s first “torture,” she and Hime end up talking so long into the night that a special extension is granted on Sakura’s report deadline.

This small exception emphasizes how emotionally significant that night’s conversation is, both for Sakura and Hime.

Torture Tortura’s flexibility here also hints at her understanding and support of Sakura’s emotional growth.

Sakura is a trained assassin, which means she is skilled, disciplined, and accustomed to dangerous missions.

Despite this, she is emotionally vulnerable and capable of deep attachment.

Her biggest defining trait is her inability to fully suppress her feelings in the name of duty.

She can play the role of a deceiver professionally, but when genuine bonds form, she struggles to carry out ruthless orders.

This emotional honesty leads to both her greatest failure and her greatest growth.

Her failure to assassinate Hime ruins her career in the Ronishi Empire, yet it also opens the path to real friendship and a new life.

Sakura is also quite earnest once she has dropped her assassin facade.

She addresses Torture Tortura as “senpai,” adopts a more open and friendly manner, and tries to fit in with her new comrades.

Her journey balances comedy and drama, blending the image of a deadly imperial assassin with that of a slightly awkward, emotionally sincere young woman.

Through her, the series explores themes of loyalty, redemption, and the power of friendship even in a world built around “torture” and war.

As a trial recruit in the Demon King’s Army, Sakura’s duties extend beyond combat.

She assists Torture Tortura and participates in various operations tied to interrogation and daily life in the castle.

After “torture” sessions, there is normally a bureaucratic requirement: post-torture reports.

Sakura is expected to handle this paperwork, reflecting her new, less glamorous responsibilities.

Her first “torture” as a member of the Demon King’s Army results in a rare exception to these reporting rules.

Because she and Hime spend the entire night talking and reconciling, she is granted extra time to complete her report.

This small administrative detail highlights the mixture of strict structure and human flexibility in the Demon King’s Army.

It also underscores how important Sakura’s personal relationships have become compared to her old life as a disposable assassin of the Ronishi Empire.
