|Appearance||The Devil's Game|
Yukari has feminine eyes and medium-length, slightly curled hair mostly worn over her shoulder with long bangs loosely framing her face. She wore long sleeved tops with skirts or pants.
Yukari is a kind girl who enjoys playing video games and interacting with others. However, she is close to Mio and cares about her, often expressing concern and trying to show support and cheer her up. She is protective of Mio and tries to steer her in the right direction.
Noticing how lonely Mio looked, Yukari approached her to talk about her poor mood until being invited to play with the other students. She walked away from the untalkative Mio but kept an eye on her, approaching her after a few days to speak to her again. But by this point Mio began to dodge her and the others, causing her to worry over her.
When Mio's obsession causes her to grow alienated from the rest of the class and the others start avoiding her, Yukari decides to confront Mio. After class she met up with her friend and brought up how their classmates are purposely avoiding her out of anger for being ignored lately. She asks if something is bothering Mio, who lashes out by claiming that everyone ignored her before and angrily tells her off after Yukari points out that it was her own unapproachable behavior that isolated her.
At the end of the chapter, Yukari returns in hopes of locating her frightened friend as she takes shelter in one of the restroom stalls. She chews out her their classmates, who reveal themselves as the ones who were chasing her, not the killer, and tries to tell Mio that the killer was caught, but just as she reaches the stall she is shocked to find Mio has gone missing- with the console left in her place.
