Haiji Towa

Haiji is deliberate and calculating, although others might call him cowardly. He is very paranoid about the Resistance's hideout, not allowing anyone to leave the place. He claims he isn't hiding, but simply waiting for the right opportunity, although he later admits that he was just being a coward and states that he probably isn't a very good leader.

He is rather serious, the one time he tries to joke around being an awkward and tone-deaf joke about Nagisa's trauma a moment after the child's supposed death. It's also implied that he was an abusive older brother towards his half-sister. Due to his strong hatred of children, he does not care for their safety, believing that they will just cause more destruction if left alive.

While he has a strong hatred of children, he is also a self-proclaimed lolicon who prefers young, quiet girls to loud, older girls. He mentions that he prefers girls to be as young as possible and in the art book it's implied that he would find Kotoko Utsugi sexually attractive if her personality was better. He seems to try to use this fact to prove to Komaru and Toko that he wouldn't do anything to them, as they're a bit too old for him.

He has a strong grudge against the Warriors of Hope, particularly their leader, Monaca Towa, for causing the chaos in the city. He also strongly dislikes the Future Foundation and anything associated with it. He does appear to be somewhat regretful of the Towa Group's unethical actions in the wake of the Tragedy, but mostly because of the problems they caused to himself and his father. Both he and his father seem to mostly blame Monaca and Junko instead of taking responsibility for their actions.

As the story progresses, Haiji becomes increasingly fanatical and obsessed with defeating the Warriors of Hope, no matter the cost. He puts all of his faith in the Big Bang Monokuma, hoping that he can turn the tide of the war in his favor. He turns increasingly aggressive and even violent, wishing to kill the children even if they were brainwashed. He also physically attacks Toko and is willing to hurt her more, though he gets stopped.
