Tsuujou Kougeki ga Zentai Kougeki de Ni-kai Kougeki no Okaasan wa Suki desu ka?

Synopsis

The academy announces a festival which the students must plan with their parents for experience points. Mamako suggests a café so Medhimama plans her own café to compete with them. Medhi later approaches Masato to apologize for her mother's behavior. Mamako's café is an immediate success while Medhimama's is ignored. To attract customers, she strips Medhi naked, but when Masato sees this, Medhimama kills him. He becomes a ghost and overhears Medhimama order Medhi to seduce him and ruin Mamako's café. Once revived, Masato angrily confronts Medhimama, who demands they compete in a waitress beauty contest. Medhi defeats Wise in the contest, but Mamako goes on stage to speak to Wise and accidentally defeats Medhi. Masato flees with Medhi so Medhimama cannot punish her. Medhi admits she just wants to have fun, but she has no friends because of Medhimama. Masato, Wise, and Porta decide to be her friends. Seeing this, Medhimama attacks Medhi, calling her a terrible excuse for a daughter, but Mamako stops her. Medhimama admits she only pushes Medhi to be the best because it allows her to claim she is the best mother. Hearing this admission, Medhi unleashes her rage and transforms into a dragon.
