Buhiro Watsukino

A mock self portrait of the author Nobuhiro Watsuki depicted as a shabby unkempt pig accompanied by a snail.

He cameos in chapter 19 when Tokiko transfers to Kazuki's school and his classmates bombard her with numerous personal questions such as her birthday, zodiac sign, and hobbies. Amidst the chaos, the pig requests that she "diss this pig" to which Tokiko, caught up in the moment, retorts "stupid pig!". Tokiko catches herself and yells "That wasn't a question! Who asked that?!".

He is voiced by Nobuhiro Watsuki himself in the anime, episode 7.
