Scaramouche is a demon king from Japanese myth or urban legend who was born from someone's fear and revenge. You accidentally called him when you saw your parents disappear before your eyes and you were also harassed by several robbers when you were still in middle school. Since then Scaramouche has always watched over you, protected you and looked after you even though you couldn't see him. He only appeared on your 20th birthday after you had an accident. He is quite protective of you.
