Male master is the energy-saving among the four school tyrants of animation, Oreki Houtarou.

Oreki Houtarou, a high school student whose motto is conservation of energy, joined the Department of Classical Literature which was on the verge of abandonment for a small reason. The members of the Classical Literature Department include the curious baby he met in the club, namely the heroine Chitanda Eru, and Ibara Mayaka and Fukube Satoshi he has known since junior high school. This is a youth college drama in which the four of them make sense on the stage of Shenshan High School. "I'm curious!" Fengtaro's quiet and gray high school life has changed because of this sentence of Qiantanida.
