Hein, Arnold

アルノルトハイン

Appearance: black hair with side locks hanging halfway above his ears, blue eyes (the color of the frozen sea)
He is the militaristic crown prince and ridiculously beautiful. He is a skilled swordsman, smart and strategically gifted, but he is feared by friends and foes alike. For some reason, he proposes to Rishe in her seventh loop and spoils her, but his true intentions are unknown.
Five years later... he becomes a brutal emperor who, after killing his father, launches a war of aggression against the world.
