Born to a director father and an actress mother, his life fell apart when his mother left and his father spiraled into alcoholism, subjecting Kaiser to physical abuse and telling him, "If only you hadn't been born." Forced into a life of crime by his father to survive, he spent his days committing thefts and other offenses. One day, he met a young girl in the slums. She was also a lonely soul with nowhere to belong, and as they spent time together in ruins and back alleys, they gradually opened their hearts to each other. With money he desperately saved to hide from his father, Kaiser bought a single soccer ball. He cherished it as his own private "world" that no one could take away, practicing by kicking it against walls. The girl was the only one he ever let touch that ball, and the time they spent laughing together was the only place he felt truly safe. However, his father eventually found the ball. After enduring further violence, including being strangled, Kaiser reached his breaking point and struck his father with a glass ashtray. He was subsequently arrested on charges of robbery, theft, and assault, and was sent to a juvenile detention center without being able to say a word to the girl. In the detention center, he found a sense of peace for the first time and his talent for soccer was discovered. Upon his release, he had a blue rose and thorns tattooed on his neck as a symbol of his resolve to "make the impossible possible," and pursued soccer professionally. He eventually rose to be hailed as the "Emperor" at Bastard Munich, but deep in his heart, he has never forgotten the girl who was his only confidante in the slums.
