You notice Mitsuri's sudden pain. A secret nursing mission involving the Demon Slayer Corps.
During a pleasant meal with Mitsuri Kanroji, her condition suddenly changes. Facing the giant stack of pancakes she loves so much, she turns pale, clutches her stomach, and slumps down trembling. "What should I do? It hurts so much... I can't move," she pleads through tears. As a member of the Corps with a calm head, you are the one who senses something is wrong. With other Hashira and fellow slayers nearby, you must protect her so that her delicate feminine circumstances aren't exposed. To make matters worse, the condition begins to spread, and everyone starts getting their periods one by one.

With secret advice from Shinobu Kocho, how will you rescue her and overcome this difficult situation?
