Gakkou Gurashi! (School-Live!) Abridged Casting Call

Yuki is a very energetic girl who can sometimes be overly optimistic and positive, as she always tries to see the best in others and things. She tries her best at everything, as the word "lose" doesn't exist in her dictionary. She is very bright and cheerful and is usually seen with a smile on her face. She is also childish, naive and an airhead, to which she often relies others to help her. Due to this attitude, she has developed a very carefree and innocent personality and can often easily accept other people's faults, and Kurumi has stated that she almost never worries, as Yuki herself has said that it would be fine if they had manga series even if their food ran out,[1] but in a comically sense.

Yuki has a very understanding personality despite her naivety, and she is also a very caring person who will try to help others, often listening to their problems and comfort them. Her presence, is also enough for others (particularly Kurumi), to feel safe.[2] She never doubts her friends: always believing in them and never leaving them alone, caring for them deeply.Yuki also often performs silly actions, something that Kurumi comments it being Yuki's "adult-like" act; though Yuki denies this.

Though her childish personality, the other girls don't mind it, since her efforts has saved them various times since she was the one who gave them the feeling of warmth and cheerfulness when everything was so stressful. She is also very innocent and funny, as she is someone who brightens everyone's spirits. As a senior to Miki, Yuki absolutely loves being called senpai,[3] and takes great pride in that Ruu Wakasa, someone younger than her, learned some "bad" (according to the others) habits from her.[4]As a student, Yuki often slept at her classes, much to her teachers annoyance. Though, her friends who were her classmates greatly cherished her and saw her a close friend, despite their different personalities.

When the outbreak occurred, Yuki was the first one to realize what was going on. She was absolutely terrified, which later made her create her own delusions; that her classmates were still alive and well, and that the outbreak never occurred. It is also stated in the manga that Yuki created the delusions to brighten the mood, especially since Yuuri and Kurumi seemed so tired and sometimes fought late at night before, and when Yuki would question about it, they would always reply with "nothing". After creating the delusions, Yuki became more cheerful, the others noticed this but didn't do anything about it, as they only wanted her to be happy. Though her teacher Megumi Sakura concluded that it was her fault that her time had "stopped".[5]

Slowly, she seems to come to realize the truth of her surroundings but still acts oblivious. However, in a situation where she's attacked by the zombies, her "delusions" will fall apart and she'll start to panic. Despite almost always having her spirits up, Yuki has her own moments of weaknesses and is seen crying when in a stressful situation.[6] She mentioned that there are a lot of people who are better than her, people who worked so hard; and she thinks why it had do be her who survived. But because of her friends in the School Life Club, she thinks that she can be here.[7]

Later on, she works up her courage to do more things, including fighting the zombies in the school to help her friends, even though she isn't very experienced in it. But due to her relying to the others all the time, she wants to help them as much as possible. After leaving the school, Yuki has seemingly abandoned her delusions, but she sometimes has delusions about Megumi, but this only happens when Yuki feels unsure about situations. Her cheerful and bright personality also remains, but she has grown to be slightly more matured and responsible.
