Hello Harinezumi

Akatsuka Detective Agency stands inconspicuously at Shimo Akatsuka in Tokyo's Itabashi ward, right above a small snack shop run by their landlord. Akatsuka's eccentric chief Kaze Kaoru founded it with her two investigators Goro and Gure in order to take on odd cases that others are reluctant to do anything about. Their motto is "to be compassionate and meddlesome", which leads them to get involved in strange situations with their clients. (imdb)
