Thoma is known by Inazumans to be a "helper", helping everyone out and ensuring that any issues are quickly and peacefully resolved. At first glance, he seems to be a very easygoing person, but he is in fact very responsible. He has an extraordinarily serious side, be it in his work or his interpersonal communications. He believes that people should happily enjoy a leisurely life and does not particularly care about his reputation, even if people speak ill of him.
