Takeo Siame
As a young demon, he began to lose his sanity, and turned on his friend, the leader of his tribe. He took a group of followers and started his own group, and mating with a quite girl, had a son whom he hoped to raise as a killer/weapon. His son grew "soft" and as a result, Takeo killed the boy's mother. His son, seeing this, ran away. Mated with another woman from his small "tribe" and they had a daughter who didn't grow soft.
Takeo wanders all over Japan, searching for his long missing son, and hopes to meet the family that his son had started.
