Lê Chiến Kim is a student in Miss Bustier's class at Collège Françoise Dupont. Kim is the "king of competitions." He enjoys making dares, much to the frustration of his classmates, and he is also very confident in himself and his athletic abilities, thus most of his dares involve using the person's body. Overconfident and proud, Kim sometimes boasts about his abilities and doesn't always take facts into consideration. Behind his bravado are a few insecurities, like his fear of being humiliated and rejected. While hot-headed and rude sometimes, Kim is generally kind.
