Shuuya Inukai is a model student at a high school who one day attracts
the attentions of an ojou-sama, Kantori Isuzu, when she realizes that he
is bearing, on his forehead, an X-shaped scar... that was also present
on her pet dog's forehead... which leads her believe that Shuuya is
actually the reincarnation of the said animal. And now Shuuya's days as
Isuzu's pet begin.
