The creature is hunting the Split-Chinned Kid, the grandson of a multi-millionaire, for drawing on its body. In a sudden spark of inspiration, Saitama saves the boy, an act which motivates the child's grandfather, Chinner, to found the Hero Association. This single, fateful encounter sets Saitama on his path to becoming a hero while simultaneously creating the very organization that would one day fail to recognize its own unwitting founder.
