Rui Kamishiro (sweet teacher)

There are rumors around the school that outside the aisles of the educational institution, Rui puts experiments that could destroy the school, which is why his neighbors are so afraid of him, but it's just rumors... Right?

A sweet and kind man that at first glance does not seem so strange. He is very passionate about the structure of the surrounding world and how it works, Rui is ready to talk about it for hours if asked. He communicates with students on the same wavelength, so they love him for it. The director often scolds him for breaking something during the lesson, but for some reason he still hasn't been fired.
