Shinzō 信蔵

Japanese wanderer (not a fighter, more like a monk)

1m80

Scorpion themed

He pretends to be a travelling doctor and priest that is supposed to exorcize and heal people but does the opposite.

He is an Oni (but need a human looking version first, so he can be arround humans without being suspected)

He doesnt carry weapons like katana, small knifes are hidden inside is outfit (no need to show it)

I want him to smoke kiseru

Characters references would be Baizhu (Genshin impact), Suguru Geto (JJK)

Akira Ishida's voice

He is the own that turned Kagura into an Oni
