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

Synopsis

Masato has developed a crush on Medhi. Meanwhile, Medhimama begins a one-sided rivalry with Mamako. Masato notices Medhi making quiet negative comments about Medhimama. Their first lesson is cookery, which Medhi manages to do well at due to Medhimama's cheating. Mamako also does well but with normal cookery, and her food is so good Masato, Wise and Porta get skill boosts and experience points from eating it. Medhi congratulates them but Medhimama is furious. In swimming class, Medhimama appears in a scandalous bikini, but is easily outdone by Mamako in a school swimsuit, infuriating her even further. In the pool, warriors like Wise and Masato are told to defeat sea monsters while crafters like Porta collect the drop items. Mamako shouts encouragement while Medhimama shouts criticism. Medhi loses her self-confidence and gives up, so a monster grabs Mamako, who beats it with her Mother Ocean Sword, allowing Masato to kill it. Masato wins first place and is bear-hugged by Mamako, while Medhimama slaps Medhi for failing. Masato tries to comfort her but she runs away, and Masato and Mamako later see Medhi furiously kicking a wall, swearing and wishing Medhimama was dead.
