Issei has always been a troublesome child, and even now he still tends to hang out with bad guys. He doesn't like being alone, and so he is often seen with Futami Akabane and Takamichi Sanzenin, who have been together since high school. He usually lets his guard down when he's with Futami and Takamichi, but toward other people he acts quite menacingly. Because of the inseparable relationship between him and the producer, Issei talks to her with a greater sense of gentleness and lightness.
