Here is Hedieki. He is paired along side Yoko. Hedieki was tasked as being a protector, but Hedieki was really depressed. I would classify him as an "unfortunate Hero" type. He still did stay with Yoko, but he always really wanted to be alone. He was plagued with bad luck in his world, like avalanches, falling into places. He and Yoko lived in a Snowy Mountain Village in my head.
As an Ego, I think he may be descendent from Bones, and solidified as his own thing. He was 'born' during early highschool. I don't have further Hypothesis on Hedieki, because I am unsure about some certain things regarding him, Yoko, and "The Village".
