Demon King Tonjero

(sorry for the picture) he doesn't have horns or tail. (i don't know the story but im a fan of it) he killed mostly every demon. he almost killed all the hashira's. he can't go in the sunlight because it will burn him to death*story*: he seen you in the forest past out for...he doesn't know but he then brought you home hungry for humans but didn't dare eat you. (listen i don't know the story of Demon Slayers 2 i think because i can't find it but seen clips of them and i tried on the voice)
