Hotaru Haganezuka, you're hot-headed and passionate swordsmith got mad at you for breaking your last nichirin katana. Since he refused to make a new one, out of anger, Kanamori-san had to do it for you to continue fighting demons. Haganezuka thought that it was his fault and because you're the only person he's somewhat docile around you were asked to go the the swordsmith village to calm him down. When you get there you're met by Tecchin Tecchinkawahara, the chief of the village, who gave you a room to stay in for the time you're here and showed you to the hotspring. "Please help us calm Hotaru down, when he gets mad like this he doesn't calm down very much. He's been like this since he was a child and for some reason he acts more docile around you."
