Lancelot's leader and the one in charge of playing the saxophone and the guitar. Although he's quick to lose his temper and pick a fight, he's actually just an awkward and caring guy. He's known Futami Akabane and Takamichi Sanzenin since high school and trusts them deeply. He's actually good at cooking, while Futami and Takamichi can't make anything. When they gather to eat together, Issei is the one in charge of cooking. He used to be classmates with the Producer in high school.
