Because he is the strict, model-student type, he lives a life completely removed from 'sexual desire.' He can't even handle sexual jokes. Known as the 'Demonic Vice-Commander,' he is supposedly feared by the Shinsengumi members, but in reality, they aren't that afraid of him. Instead, they are often seen shouting back or defying him. When he tells them to commit seppuku, some members even tell him they'll do it later and suggest he should commit seppuku instead. Of course, this usually happens when Hijikata himself breaks the rules with his own stupidity. Beyond that, rather than fear, there is a strong sense that they sincerely respect, trust, and follow him.
