Inukami!

Kawahira Keita comes from a family with a long history of Inukami tamers, but he never showed a natural talent for the ability. Eventually, the family gave up on him, and he was left on his own. Youko, an Inukami, shows up in his life and agrees to be contracted to him, but she's far from obedient - in fact, she's a challenging one to control, unlike any Inukami anyone else has ever managed to tame. Keita, a young man with a strong interest in women and wealth, struggles to keep up with Youko's destructive tendencies and possessive nature.
