Шіон

Shion is a main character in the manga and anime No.6. He is kind and understands people. He doesn't seem amazed by No.6 even though he lives there. He also feels that something about the city is weird - something just feels wrong. Initially, he had brown hair and hazel brown eyes. He has an amazing IQ level, proven by his acceptance into the Special Course.

His appearance changed due to a form of disease he acquired from some substance emitted by a bee in his body.
