Yuki Takeya is the main protagonist of the Gakkou Gurashi! series. She is a former senior student at Megurigaoka Private High School and a member of the School Life Club, where she, as the most cheerful and optimistic person, comes up with club activities and brings comfort among the club despite their surroundings.

Spoiler

Yuki is oblivious to the fact that she is in the midst of a zombie apocalypse and the "activities" of the club are survival missions. Not wanting to disturb her already fragile mental state, the other girls go along with her ideas.
