Character History
Early LifeNikaido Hiro andEmma SakurabaandTsukishiro YukiThey were close friends in middle school. Because Yuki suffered from severe bullying, Hiro, who pursued "correctness," always protected her with her own strength. Later, because Hiro was going to study abroad, she entrusted Yuki to Emma. However, upon returning to the country, Hiro witnessed Yuki hanging herself due to the bullying. Hiro learned that Emma chose to stand by and watch the bullying to protect herself, and thus began to hate Emma, while also being left with the trauma of being "extremely sensitive to suicidal behavior."  Emma's ChapterIn Emma's Chapter, she is kidnapped to the Witch Prison along with 12 other girls. She wakes up in the same cell as Emma. She shows an unusual sense of loathing toward Emma. After following the other girls to the drawing room, she loses emotional control because the Warden labels them as villains, attacks the prison guards, and is immediately killed by a guard's counterattack via decapitation. In the subsequent plot of Emma's Chapter, Hiro appears only in the form of Emma's memories. During the picnic after the Milia case, Emma tellsToono Hanna，Hikami MeruruandTachibana Sherryrevealed that her relationship with Hiro was that of childhood friends, but she was hated by Hiro for reasons she couldn't remember. At the end of Emma's Chapter, Emma turns into a witch as her trauma is exposed, gradually losing her sanity and consciousness. At the very end, Emma remembers Hiro again and says she doesn't want to forget her. Hiro's ChapterNikaido Hiro is the main perspective and first-person narrator of the Hiro Chapter. At the beginning of the Hiro Chapter, it is revealed that Hiro's magical ability is "Death Loop": once she dies, time returns to the morning of the day she died. Having learned from her previous experience, Hiro chooses not to rashly attack the prison guards this time.  While in prison, Hiro's relationship withHasumi ReaandShirosaki Noawas relatively good. Because she is roommates with Emma, Hiro often feels extremely irritable, and has described many times in her diary that this is the reason she cannot maintain her sanity and control her witchification process. After the judgment of Meruru Hikami's case ended, Hiro, who watched the cruel execution process, witnessedinfluenced by Yuki andEmma smiling, and thus concluded that Emma was an evil witch, believing that killing Emma was the "correctness" she must execute. She devised a plan to kill Emma, but on the day of execution, it was forcibly interrupted becauseSawatari Kokowas suddenly murdered. Because she and Emma appeared at the crime scene at the same time, the two accused each other of being the true culprit, but the subsequent trial revealed that the true culprit was someone else. During the trial, Emma bluntly revealed that Hiro's killing intent was directed at herself and used this as a reason to defend Hiro, which improved Hiro's feelings of hatred toward Emma. After the Sawatari Coco case, she watchedKurobe Nanokathe message left behind, and learned that the culprit behind the Witch Factor disaster was an existence known as the "Great Witch." In the process of deciding to investigate the Great Witch, she gradually opened her heart to the other girls and took the initiative to help plan Hasumi Rea's stage play, being active in logistics for a while. One day, in Noah's studio, she sawNatsume An'an[An-An] having a dispute with Emma. While trying to break up the fight, she accidentally pushed An-An off the balcony and witnessed the horrific sight of An-An's body being impaled by the courtyard fence. At this moment, to Hiro's surprise, Emma began destroying evidence at the scene that was unfavorable to Hiro and tried to take the blame herself. Although the subsequent trial determined that the killer of An-An was someone else, the events and outcome of this case made Hiro's feelings for Emma increasingly complex. After the Natsume An-An case, the relationship between Hiro and Emma significantly warmed up. Hiro accidentally overheard Emma's sleep-talking about Yuki and realized that Yuki's identity might not be simple. With the help of the other girls, Hiro investigated the body of Meruru, who had been confirmed as a witch, and found a photo of Meruru with Yuki. She finally confirmed that the Great Witch, the source of all evil, was Yuki, and that Emma was a victim exploited by Yuki. Filled with regret, Hiro wanted to apologize to Emma, but at that moment, she directly witnessed the scene of Emma and Rea being murdered. After the Emma and Rea case, Hiro returned to her cell and heard Yuki's voice. Yuki ruthlessly mocked Hiro, saying she was the biggest mistake, and reminded Hiro that if she tried to commit suicide to activate her magic, it would trigger her trauma, causing her to fully witchify and lose her sanity, and that she had no more chances to start over. Hiro fell into despair for a time, but with the help of the survivingSaeki MiliatoShido Arisa[girls], she deciphered the "Witch's Rest Ritual" method to summon the Great Witch, which the girls had worked hard to crack during their many days in prison. Carrying the wish to save everyone, Hiro mustered her courage and chose to activate the "Death Regression" magic by committing suicide, hanging herself in prison. Witch's Rest ChapterBecause Hiro's witchification was already severe before her suicide, her "Death Regression" was able to successfully exceed the 1-day limit, returning to the first day she arrived at the prison. However, the "Death Regression" activated at the cost of exposing her trauma also caused Hiro's body to rapidly mutate, nearly losing her sanity. To perform the Witch's Rest Ritual, Hiro continuously exposed the traumas of the other 12 girls during the final trial, causing everyone present to successfully witchify and summon the Great Witch, Tsukishiro Yuki. Ultimately, Hiro, Emma, and the others successfully found Yuki's psychological weakness, causing Yuki to abandon her long-held revenge plan. Facing Yuki, who decided to commit suicide at that moment to reclaim all Witch Factors, Hiro said she had always considered Yuki a dear friend and stated she would never forget her.
Endings in the gameAfter the Witch Factor incident was resolved, the 12 girls were permitted to be released after being confirmed safe. Hiro still felt guilty toward Emma for hurting her and intended never to see Emma again until she had atoned for her sins, but Emma caught up to her before she boarded the plane to leave the prison. The two finally revealed their true feelings to each other and eventually reconciled, embracing without any barriers between them.

Trivia
You're wrong, I am not evil
while uncontrollably bashing the prison guard with the poker in her hand, only to be instantly decapitated and killed by the guard's counterattack. Due to the rapid pace of this plot development and the sheer number of absurdities, it has become a staple for bullying the character since the release of the game's trial version.

What should I say to Emma...In the latter half of Hiro's route, Hiro finds a photo of Yuki and Meruru from Meruru's preserved corpse on the ice in the underground facility, subsequently realizing she had been misjudging Emma all along. She comes to the elevator in the underground facility to apologize to Emma and encounters Sherry, Hannah, and Millia, who want to return to the surface. Since the elevator's maximum capacity had become one person at this time, Hiro had no choice but to send the other three up the elevator first in three separate trips. When she was the only one left in the underground facility, Hiro had the following inner thoughts:
Just as Hiro was thinking this, the elevator doors opened. Hiro witnessed Emma's murdered body inside the elevator firsthand and immediately let out a heart-wrenching scream. Although this plot point itself follows a very cliché formula, because the scenario is something players love to see, combined with Emma'shighly aestheticimpactful death CG and Hiro's CV's東雲はるimpressive performance, it quickly became a target for endless memes among many Majo Shinpan players after the official release.
