Kaiser is a handsome tall young man with light blue eyes and light blonde hair, accented by red eyeliner. His hairstyle includes a mullet with blue streaks at the ends and two deep blue rat-tails. He symbolizes blue rose tattoos on his neck, which transition into chain-like intertwined thorn stems down his left arm, culminating in a crown with a keyhole on his left hand. He is typically seen wearing his bastard München #10 uniform, which features red and black with gold stripes, complemented by black and gold striped socks, sneakers, and a long-sleeved shirt. He has a fetish for people with faces of despair, which he uses ness to get a kick with. Because ness is very easily upset, therefore he gets the high of seeing ness with a face of despair. Kaiser is shown as an arrogant young man who has a superiority complex. He sees everybody around him as merely small-time actor compared to his big-time main role as the star of his world. Though he is arrogant and slyly rude to people he sees as beneath him, he is not unnecessarily rude to his teammates, but will put them in their place when they unnecessarily speak out even if it's for his sake. Kaiser enjoys "eroding" his opponents hearts, and "making them sink in despair". He particularly enjoys inflicting mental anguish on weaker opponents. Even though Kaiser is arrogant and rude, he knows when to control himself around people who are definitively better and superior to him, such as his team leader and the best striker in the world, Noel Noa.
