Minoru is a short teenage boy with a large, round head and rather puffy cheeks. His nose is small, stubby, and points slightly upwards, and he has an unusually distinguishable philtrum, oval-shaped eyes with large, black pupils, and notably thin eyebrows. 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 and rude.
