Bakeneko OL Tamami-san: Omoi Tsuzukete Nanadaime

Tamami-san is a bakeneko, an immortal cat-human, seeking revenge on all the descendants, to the seventh generation, of the man who scarred her for life. But to hunt down those descendants, she needs money. For money, she needs a job. Days in the office, nights out hunting. No wonder she can't stay awake!
