More Characters from Jigoku Sensei Nube

In no particular orders:

Kasiya

A boy who has a good heart but a tendency to go astray (smoking, stealing etc.) Hi vices often get him into trouble.

Hayame

A mermaid (cute, of course) who was unintentionally resurrected by Nube, to show her gratitude she tried to get Nube to eat her flesh which would make him immortal, she suggested all kinds of cooking her flesh for him (fried, bake, grilled, sushi!) but Nube didn't want any. He eventually suffered from a fatal wound and had to eat a bit of her flesh (it's OK, she regenerates!). Hayame likes to sing and has the power to influence people through her singing (as in the Siren legend), she once used this talent for a very good course and brought t about something akin to world peace!

Isuna ("Itago girl")

Descendent of a long line of spiritualists (exorcists?) She has pretty strong psychic power but nowhere near as strong as Nube, she usually overestimates her ability and often get herself and others into trouble. She would like to use her psychic ability get rich, and her attempts are almost always disastrous.
She also has pyrokinesis power (a la Stephen King's Fire Starter)and keeps little pet demons (called something like "kudangisune").

Kurita Makoto

The smallest boy in Nube's class, he looks at least 5 years younger than al the other kids in Nube's class. I suspect he isn't all that much younger than the others, he's just small, is all. A bit of a cry baby, possibly due to his diminutive stature, not very good at school work. He is nice kid, and everybody seems to like him.

Moriko

A "goody two shoes", very polite, always prim and proper. She is never mischievous like Miki and not outspoken like Kyoko. She was once possessed by a nymph-like spirit and totally outdid Miki in the sexiness department!

Akira

This student is a bit of a mad scientist, always coming up with weird devices which usually cause trouble!

Suiji

The richest boy in the class, likes to show off his wealth, and can be snobbish at times. He is very interested in UFOs and monsters (not the supernatural kind, more the Big Foot and Nessie variety!)

Mazaru

The token school bully. He's chubby, dim, and likes to intimidate other students. He has shown on a few occasions that he isn't really as bad as he makes himself out to be.
