Joukyou Koroshiya Musume

Born and raised in a rural town by a family of hitman, Chiharu Tamamano has spent the two years since graduating high school living a quiet, modest life as naturally a hitman herself. No dreams, no boyfriend, and still living with parents; her days are mostly "work" and spending time in the local shopping mall.

But her peaceful countryside routine is suddenly shattered when her mother announces, "I've found a new man," and orders Chiharu to move to Tokyo.

Thrown from her calm, comfortable rural life into the overwhelming big city, Chiharu must face unfamiliar challenges at every turn. Will she be able to survive the hitman trade in Tokyo and secure the "sparkling city life" she's been promised?
