Penguin 2

A penguin who's always seen accompanying Shouma. He is perpetually hungry, eating anything and everything in reach. He has a vendetta against bugs, particularly cockroaches. He sprays them with bug spray whenever possible. He is sometimes seen spraying things other than bugs, hinting he may just like spraying things.

It is hinted in the last episode that his perpetual hunger is because of Shouma's original fate, in where it was intended for him to die by starvation.
