Fuchi

Ranked as the 9th seat of Yamada Asaemon, Fuchi is a prodigious figure within the Yamada clan, renowned for his mastery of medicine and anatomy. Assigned to the mission heading to Shinsenkyo, he serves as the overseer of death-row convict Tamiya Gantetsusai. Though his obsession with dissection initially earned him the reputation of a cold-blooded 'madman,' his true character is deeply upright and he holds his comrades in high regard. Drawing on his medical expertise, he has repeatedly saved his allies in battle, and over time has forged a profound bond with Gantetsusai that transcends life and death—making him an indispensable pillar of the team's medical and logistical support.
