Michael Kaiser

Kaiser is a tall, handsome young man with light blue eyes and light blond hair, outlined in red. His hairstyle includes a mullet with blue highlights at the ends and two dark blue pigtails. He has tattoos of blue roses on his neck, which extend like chains intertwined with thorny stems along his left arm, culminating in a crown with a keyhole on his left hand. He is usually seen wearing the number 10 uniform of Bastard München, which is red and black with gold stripes, complemented by socks, sneakers, and a long-sleeved black and gold striped shirt.

Kaiser is portrayed as an arrogant young man with a superiority complex. He considers everyone around him mere supporting actors compared to his starring role as the star of his world. Although he is arrogant and subtly rude to those he considers inferior, he is not unnecessarily rude to his teammates, but he will put them in their place when they speak out of turn, even if it is for their own good. Kaiser enjoys "eroding" the hearts of his opponents and "drowning them into despair." He especially enjoys inflicting mental anguish on weaker opponents. Despite his arrogance and rudeness, Kaiser knows when to rein himself in around people clearly superior to him, such as his team leader and the best striker in the world, Noel Noa.

After the battle against Ubers, Kaiser was deeply frustrated at having lost to Isagi for the second time. He had originally joined Bastard Munchen because it was the fastest way to enter Re Al, but he decided to withdraw in order to defeat Isagi.

In the past, Kaiser was a weak-minded person who constantly gave up on anything he considered impossible. To remind himself never to fall back into that weak mindset, he tattooed a blue rose on his neck, which, according to him, symbolizes achieving the impossible. Kaiser believes that the moment people think something is impossible, they are programmed to give up. He despises those who sacrifice their talents for a long and tedious life.

During the PXG match, Kaiser perceived Isagi as a threat to everything he had built. He sacrificed his emotions and pride to reach a state of absolute rationality, following the most logical option without being swayed by his feelings. He began involving Blue Lock players in his plays, passing the ball to Jingo Raichi and Rensuke Kunigami, despite having deliberately avoided them in previous matches. Realizing that Rin Itoshi was too unpredictable to face alone, Kaiser accepted Isagi's contract and partnered with him, on the premise that the better player of the two would score the decisive goal, giving Bastard Munchen the victory. However, during the final minutes of the match, Kaiser underestimated Ness's growth potential, failing to account for his spontaneous awakening, which resulted in another goal for Isagi, further frustrating Kaiser.
