Minoru is perverted to the point of infamy, which makes him unpopular with the girls and even some of the boys, who consider his interests and mannerisms depraved. When an opportunity to peep at the girls arises, Minoru becomes very determined to take it, although this often leads to painful results. He can also be very hypocritical, criticizing others for perceived perverted behavior even if they turn out to be misunderstandings. His interest in women is one of his motivations to become a hero, alongside general popularity.

Minoru easily freaks out in moments of great stress or fear, acting in an impulsive way, crying when the situation does not look favorable and abusing his Quirk recklessly, to the point of hurting himself in the process. He is quite unashamed of those traits, openly admitting them out loud.

Minoru has a habit of rubbing salt in people's wounds, both accidentally and intentionally.
