Truman

I can imagine him as a mailman who hops between different worlds and would make him some form of demon. Might name him Yagi or Gata. Physical age would be around 20-30 yo and will add some horns and more demon traits to him. Might give him some funny fire pocket knives too because that sounds cute. I'd place them in this story I'm working on hehe https://toyhou.se/tapewormslurper/characters/folder:1111866
