Sumadera Yukio

A girl from Kida's school. Yukio is respected and admired by the underclassmen, who see her as an intelligent and beautiful senpai. Though Yukio seems to have an ideal reputation and proves to be a very capable young woman, she has decided to abandon the idea of forming bonds and connections with others. She also seems to dislike being the object of people's affections.

Yukio always questions about fate, if humans are just playthings for the gods. In her route, Yukio asks him straight in the face "do you want to have sex with me? You look like you want to." and they go into a love hotel. They keep on this "body relationship", while the main character tries to understand more about Yukio, she keeps her distance. Has a broken family life and afraid to loose something else she dears again. At the end, both of them decided that there is nothing left in this world for them and jump off the roof. They end up surviving, though. When they came to in the hospital later, Yukio then finally acknowledges that they do have choice and not everything is completely governed by fate.
