WARNING: THIS CONTAINS HEAVY SPOILERS FOR THE MANGA SERIES "Danganronpa Gaiden: Killer Killer".

Misaki has a difficult time trying to understand Takumi and his odd behaviors, and often gets frustrated with him as a result. However, she continues to make an effort to understand him, even if she herself finds his habits and personality to be sloppy. Her concern for him is shown when she takes Takumi's invitation to hide underneath the sink with him and waiting in his hospital room for him to wake up.

Misaki has enormous difficulty believing that Takumi is the Killer Killer at first, having seen him in an entirely different light during all the time she spent with him. However, she has no other choice but accept the reality of things as she witnessed Takumi's Killer Killer persona in action as he faced and murdered the numerous Mukuro lookalikes. She was sad at first knowing that his true identity as the Killer Killer. However, Misaki understands that he turned himself as a serial killer who kills serial killers after he experienced a deadly experience such as Giboura Massacre. Eventually, after Shūji planted a bomb choker on her neck, Misaki begged Takumi to kill her, exclaiming that by killing her, he'll get the 'Passionate Killing' he yearned for. Takumi then 'severed' her head to discard the choker before her head is reconnected by unknown means.

Days later, Misaki met Takumi again in the similar manner when they first met. Takumi then hugged her and proposed to do "Super Lovers Suicide" together with her, which she complies, implying that both of them had romantic feelings for each other. Their fate is left unknown.
