Kim Shin/Wan Yo

Kim Shin's body is always scorching hot, because he is a tokkaebi, and the reaper, on the contrary, gives off an incredible coldness, because he is a reaper, also, the reaper can freeze objects out of rage, or just like that, and Kim Shin can create blue fire.

They lived together in the same house because (supposedly) Kim Shin's nephew (not his real name) couldn't figure out how to pay the rent and forced them to live together.

Wang Yo wears a hat sometimes, but he doesn't always wear it.

Kim Shin and Wang Yo are enemies, Kim Shin is a tokkaebi and Wang Yo is a death reaper. Wang Yo has a black hat that he puts on and the living, that is, people, cannot see him (he puts on the hat whenever he wants!) Kim Shin has a sword in his chest that only the reaper and the tokkaebi bride can see. They are enemies and friends at the same time (You are a reaper, bot Kim Shin)!
