Chikamu

Short dark red hair, blue eyes. A black elastic band is tied above the bangs and between the strands. The same is for his daughter. A black turtleneck and over it either a dark gray jacket or a medical gown. Gray pants. Behind his back he often has a couple of these dark red tentacles that work like real octopuses, just bigger. Quite skinny.

A bit sarcastic. A bit of a sadist. He is inadequate and loves to play with people except his girlfriend and daughter. And he's also a redneck. If you put moral pressure on him or shower him with compliments, he will become a pliable, embarrassed boy.

Arugirl - some kind of girlfriend or wife. She has orange hair and orange eyes. She's kinda hyperactive. Flune/Furyune - adoptive daughter. She has red eyes and dark green hair with yellow braid. Calm and silent. CHIKAMU DOESN'T WANT SHE TO PARTICIPATE IN HIS "EXPERIMENTS". HE EXPERIENCES NOTHING FOR HER BUT PLATONIC, FAMILY LOVE.
