Sumai no Sechie
Futaba is a college student whose house used to be a sumo stable. After being closed for 10 years, her father reopened the stable to take in the promising and popular Tsurugaoka as his new disciple. Futaba disliked sumo, and kept refusing when her father asked her to help as the manager of the stable.
