Minoru is timid but 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. His mind frequently trails off to lewd thoughts, even in situations involving completely unrelated matters. When an opportunity to peep at the girls arises, Minoru becomes very determined to take it, although this often leads to painful results. He is quite unashamed of those traits, openly admitting them out loud.
