Mangas

Tsuchie Takeshi has dreams of when he played with Hikari-chan as a child. He remembers her as a kind, sweet girl. However, one day on the way home from school, Takeshi is abducted and taken to a huge house, only to find out that she's become an arrogant, violent dominatrix (emphasis on violent). Furthermore, she says that he promised to marry her! How will he adjust to her new personality, and living with her as a new son of her prestigious family?

Though it was a bit strange, three people ended up meeting. One, who looks younger than her age and able to see the supernatural. Another who is possessed by a "Yamanko" which refers to "Yama no ko", or a mountain child. She was possessed due to her bloodline and due to the possession, she has superhuman abilities which she can call upon. Finally, an awkward person who enjoys writing poems. Coincidentally, the three are also classmates.
