Sukuno no Shinoi is a Mazoku(Familliar but different from youkai) he himself is ruler of place called "Makai" and has a personal grudge against a Certain Miko who messed it up all(Guess who is it) Sukuno prouds himself to be "Big Demon Lord" and often thinks youkai are pathecic(blud calls them "Ressa" not Essa "Akuma") Sukuno is easy to anger(say cringe he says "peace was never an option") Sukuno holds a Uchigatana(Long sword trope yeah ik) Sukuno magic is based upon malice and fire.
