Hiroshi Satou

Hiroshi Satou is from the same class as Reita. He is the epitome of an ultimate normal guy, everything that Kusuo has ever wanted to be. Hiroshi was first introduced as someone who gets the same rank in school as Kusuo. Someone who has boring name, common appearance, average in brains and body and has no single quality to stand out. He blends into the background, so the other characters tend to lose sight of him. Hiroshi has his own circle of friends: a chubby guy and a skinny glasses guy.

He is completely average in everything he does. His grades, height, and weight are exactly average. Down to the millisecond, Hiroshi is timed to have the exact average times for the PE evaluation. He is also noted to go to the bathroom for the average amount of time and use the average amount of toilet paper.
