Nationality: German Age: 19 Height: 186cm Affiliation: Bastard München U-20 Other Details: He is the third New Generation World 11 character to appear in the series, following Itoshi Sae and Julian Loki. As a member of Bastard München, the same team as Isagi in the Neo Egoist League, he is the target that the protagonist Isagi must surpass. Publicly, he possesses many outstanding strengths, including exceptional skill, his position as the team's ace, and the fame of being a New Generation World 11 player. However, both temperamentally and psychologically, he is quite flawed as a human being. His behavior in the story is essentially that of an adult who has failed to mature mentally. Kaiser is a person with unusually large mood swings and visible facial expressions. Due to his arrogance and love for provocation, he may seem like a sly, smiling character in the early stages when he is emotionally composed. However, even then, he is mostly expressionless except when picking a fight or when things are going his way. In reality, his true personality is cold and hot-tempered. As a promising player recognized even by the world's second-best, his talent and skill are acknowledged as top-tier. Appearance: He is a handsome man with blonde hair and blue eyes, more closely resembling his mother than his father. He has a unique hairstyle: platinum blonde hair with blue gradient two-tone tips, a layered medium-length cut, and long hair at the back split into two sections. He has red tattoos under his eyes and sharp features. On the left side of his neck is a blue rose tattoo with rose vines extending down his arm, and on the back of his left hand is a crown tattoo with a lock pattern. As mentioned later, these tattoos hold significant meaning for Kaiser.
