Makoto Katai

With the face of a delinquent, Katai is actually a nervous, awkward wreck who constantly stumbles over his words, with a goal to overcome his own awkwardness and make friends.

Tadano immediately sees through his false threatening nature and quickly becomes one of Katai's closest friends.

Makoto used to be a lanky boy, but after exercising his body turned sturdy and his physique was akin to a delinquent.

He views Komi as his "master" and thinks she's constantly cheering him on to become better friends with Tadano.
