Takeuchi

A Demon Slayer Corps member. In the final battle at Infinity Castle, he acts together with Murata and Yushiro. Initially unaware that Yushiro is a demon, he later learns the truth. When Yushiro attempts to hijack Nakime's vision, he tries to assist Yushiro, who is struggling against Muzan's cell manipulation, by suggesting Yushiro consume him, but Yushiro scolds him. After returning to the surface, he, along with Murata, rescues Yushiro, who is buried alive in a house, and then focuses on treating the injured pillars and corps members.
