雲雀13

Amakusa Jūza is a Yamainu soldier who is part of the Hibari unit. In Matsuribayashi-hen, he is sent to stop the club with others members of his unit. Satoko provokes him, and when he tries to chase her in the forest despite warnings from the base and his fellow soldiers, he falls into her trap. While it is unknown what specifically happens to him afterward, he presumably receives the same fate as his fellow members after Okonogi gives the Yamainu the order to surrender themselves to the Banken.
