Yashiro Isana

Height: 169 cm

A joker who goes around asking for his schoolmates to share their lunch with him. Yashiro is soft-spoken but very charismatic. He is very friendly and well-liked. In addition, he is quite respectful towards anyone he meets, even robots. He is also somewhat laid-back and happy-go-lucky. Yashiro carries also a red, Japanese-style parasol with him at all times.

~!His real name is Adolf K. Weissman and he's the Silver King. The Colorless King was once in control of "Yashiro's" body, but once he took control of Weissman's original body, their spirits switch. He had amnesia from episode one and regains them in the 11th episode, finally bringing light to the confusing situation.!~
