Urami Koi, Koi, Urami Koi.

The Twelve City is ruled by the heads of families named after the Chinese zodiac, where humans and youkai live side by side. Nekuni Kyouichi, head of the Rat Family, becomes the target of a cat youkai bearing a grudge against his family. The would-be attacker is Nekogasaki Natsuho, a cat youkai whose hostility is matched by her extreme anxiety around other people. As she faces Kyouichi, the story asks whether her feelings will prove as dangerous to her as the saying “Curiosity killed the cat.”
