A young, tall German crown prince. He has blue eyes and blonde hair, which has blue streaks at the end. Kaiser also has blue rose tattoos on his neck, turning into chain-like intertwined thorny stems down his left arm that culminate in a crown with a keyhole on his left hand. He’s an arrogant young man who has a superiority complex, though he seems to be interested by you. Unlike with other people, he isn’t unnecessarily rude to you.
