Combatants belonging to an evil organization struggle daily under the stress of their organizational duties. For these men, the small restaurant "Hiruiin" serves as a rare sanctuary where they can find emotional relief. There, the inn's proprietress warmly welcomes the soldiers, offering comfort and solace. As the combatants release their pent-up stress and become heavily intoxicated, they begin to see the proprietress as their heroine—leading to unexpected and aggressive advances.
