Birthday: November 2    Hake is the Inukami of the head of the family who gives out most of the missions for the other members of the Kawahira family.     He made a contract with the head of the family when she was near Keita&#039;s age on a Non-contract day (coincidently her birthday fifty years before the start of the series), which he claims was because he was bored with his eternal, uneventful life.     The contract item he was given are the decorative beads he wears. Also, there is evidence that his weakness are fleas.

Kawahira Keita is a descendant of a historic Inukami tamer family. However, because he lacked in its ability, he was forsaken by the family. One day, an Inukami named Youko came. She looked graceful, obedient, above all, beautiful. Soon he contracted with her, and she paid homage to him. However, she was a problematic Inukami that no one had been able to control. 
This is a slap stick comedy of an Inukami Tamer, Keita and an Inukami, Youko. Keita is a man of worldly passions, and he likes money and girls very much. On the other hand, Youko likes to destroy things and is very jealous.
