Kashu Remu♂

A mad scientist-like chemistry teacher who likes exciting experiments. With no interest in this transient world, he's more the type to float around in his environment but he's very much pleased with this academy because it's abundant in experimental material. He hates tedium and will immediately drop anything that's boring. Conversely, if you satisfy him, his feelings will run so high you can't limit him anymore. He likes sweet things and eats sugar cubes when he's tired. It seems that Kuzuha will occasionally bring him food.
