Takuma Onizaki

Height: 178 cm

The first guardian the main character meets and also her classmate. He has much strength, but is also quite slow. His hobby is doing crosswords and he enjoys eating taiyaki. He is the descendant of the oni, whose power is very hard to control, especially when near the sealed magical sword Onikirimaru. He gets along very well with Tamaki and is very close to her.
