Chigusa Senrou

Chigusa is a man suffering from amnesia, only retaining his memories of his homeland, his name, and his goal of eliminating the Ayame. Due to the plants in his body, he can turn his blood into bandages and cannot feel pain. For all intents and purposes, he is immortal. He has superhuman eyesight and fights using a gun made of plants. He used to be a remorseless killer, however, his relationship with Rakan changed him. He is very fond of Rakan and devoted himself to protecting him. Chigusa often displays his affection for Rakan in odd ways, causing him to be labeled a "pervert" by his companions. He is from the Senrou clan who are considered to be criminals.
