The title says it all. No GenMui, genmui isn't my main ship in this relationship, only gentan and muitan. If I'm being honest, I think it's weird. Only for me, IT'S MY OPINION!! This is during Tanjiro's trail and during Tanjiro's training with Muichiro(after swordsmith village arc) ! Bottom Tanjiro only ! One shots!

The story of muitanyui. Yuichiro and Muichiro looking for a husband, they find Tanjiro, the manger of the café near by
