Donten ni Warau

In the 11th year of the Meiji Era, when swords were outlawed, the samurai population dwindled and violent unrest spread throughout the countryside as those who rejected the ban on blades rebelled. To combat the rise in criminal activity, an inescapable lake prison was constructed. Three young men from the Kumo line have been entrusted with the duty of delivering criminals to their place of confinement, but as they navigate their mission, they begin to uncover a complex web of secrets and motivations that threaten to upend their understanding of their role and the world around them.
