Danchigai (だんちがい, lit. "Big Difference") is a Japanese four-panel comedy manga series by Kazusa Yoneda, serialized in Ichijinsha's seinen manga magazine Manga 4-Koma Palette since June 2011. The series received an anime adaptation, which aired between July and September 2015. The story revolves around Haruki and his four sisters: Mutsuki, Yayoi, Uzuki, and Satsuki. While they may seem monotonous aside from the fact that Haruki's sisters don't give him a single opportunity to rest, lecturing him about every perceived mistake and playing tricks on him, he still loves his life.
