Arisaka, Shiori

有坂秋桜里

The unfortunate new homeroom teacher at this unusual school, who truly has no idea what she has gotten herself into.
An extremely earnest young woman, she can end up letting people walk all over her in her efforts to accommodate them. She is perhaps best described as 'unassuming'—or, more to the point, 'cowardly.' She would not look out of place as a nameless NPC in some generic role-playing game. She does not have much luck at work; she is the type to end up causing a huge calamity, and then get caught out straight away by her superior.
According to Arisaka herself, she was equally unlucky as a kid—she has always drawn the short straw. Sometimes it can genuinely seem like she is cursed.
Other than that, though, her life is pretty ordinary. Mundane, even. That can seem like a breath of fresh air somewhere like Mihama Academy. Like everyone else, she appears simply to have drifted into the school.
