Karashi is the rabbit from the story "Fire-Crackle Mountain" and one of the best tormentor demons in Hell. Although appearing innocent and cute at first glance, she claims her motto is "slow retribution" and wishes to fight against today's poor morals.

She seems to bear a grudge against the crime-committing raccoon in Fire-Crackle Mountain, as she keeps a diary where "damn that raccoon" is written repeatedly and goes on a wild rampage every time he is mentioned.

Despite her inner violent nature, she has the typical attention span of a normal rabbit, stopping halfway through her self-introduction when she spotted a grassy spot to eat and lie in.
