Compared to his peers, Tetcho has a more serious character, despite the fact that he meets all the requirements of an eccentric guy. For example, he has a habit of combining foods of the same color and then eating them; he can watch a colony of ants for eight hours at a time or periodically exercise his muscles, even during meetings. As a member of the Bloodhound organization, Tetcho takes his job seriously. He seems to be the least cruel of them all, expressing his dislike for people who torture others during their investigations. For example, Suehiro used his position to track down Agency members and their accomplice after the owner of the Uzumaki cafe tried to protect them. At the same time, Tetcho showed respect for the man who tried with all his might to protect the people dear to him. Snow Plum Blossom is an ability that allows Tetchō to increase the size, shape, and length of his blade. He is quite adept at negotiating with others during interrogation, preferring communication over force in extracting necessary information. It is noteworthy that his approach to negotiations is completely opposite to Jono's threatening interrogation tactics.
