Hidetora Toujou

The fourth Touhoushinki (TKKH) member. He is by far the strongest member of the Touhoushinki (his strength in comparison to Kunieda is not confirmed, though it can be implied that he is stronger than her indirectly from their other fights). Toujou has an unexpected soft side towards smaller creatures and babies, though said creatures do not feel similarly towards him. He is mostly bored with weaklings and is always looking for a good fight, which subsequently leads to his interest towards Oga. He works multiple jobs and sometimes has to miss school because of them. He can feel Saotome using his demon power, which shows he has notable strength for a human.

He appears to know the female horsemen from Saint Ishiyama Academy (Shizuka Nanami) quite well. She referred to him as Tora when they met after the volleyball match.
