Listol is the president secretary of the Criasu Corporation. For the sake of the company's goals, Listol is very strict not only towards his subordinates but also with himself. In combat, he can come off as merciless and doesn't hold back when he strikes.

Despite his strict personality, he have a soft side towards his loved ones, particularly Bicine, as he embraces Bicine (who is in hamster form) through his own hamster form, allowing the latter to let out his anguish. He, in fact, has a lot of care towards Bicine's welfare, as he correctly guessed that he's after Harry just by Traum's words during the summer festival.
