Danchigai focuses on the life of Haruki Nakano and his four sisters, all of whom live together in the same apartment complex. The only boy of five siblings, Haruki lives with his older sister Mutsuki, difficult younger sister Yayoi, and mischievous twins Uzuki and Satsuki.
Like Minami-ke, Danchigai follows the daily lives of a group of siblings and also has a very similar sense of humor based on random antics, though Danchigai's episodes are quite shorter than Minami-kes, so if you liked Minami-ke and you want something shorter then Danchigai is for you.
