Doukyo Shiteiru Kensei no Onna Shishou ga Kawaisugite Mainichi Shiawase desu

Eugene Dawson trains to become stronger under Liza Pulsandra, the swordswoman celebrated as the Sword Saint. In training she is nearly flawless, strict and powerful enough to make every day a genuine test of his ability.

At home, Liza is far less organized, and Eugene discovers that living with his master means handling ordinary details that have nothing to do with swordsmanship. Their constant closeness makes him increasingly aware of his feelings for her and turns some training sessions awkward when they should be serious. Caught between admiration and a sincere desire to improve, Eugene tries to keep his focus and prove that he can someday become a swordsman worthy of standing beside his teacher.
