Because Mob didn't want to hurt other people, even for self-defense. He refused to use his powers on another person even when being choked to death by Teru.

When Koyama showed up, it would be even less likely for Mob to do a complete 180 and go all out from the start; he held back a lot to simply knock Koyama out, but severely underestimated Koyama's strength. Then Koyama started beating Mob up, without giving him a chance to use his abilities, until Mob exploded with animosity; even then, he held back a lot and told Koyama to leave them alone. Koyama only escaped because Mob got knocked out by Sakurai's pepper spray.

After that incident, Mob started to let go of his previous stance and used his powers to legitimately harm other people, starting with sandwiching Terada between a few trees and commenting that there are other ways to use his powers. When Koyama showed up again, Mob didn't want to waste any time and is serious from the start, leading to Koyama's pathetic defeat.

You can see a similar pattern with Mob's fight with Tsuchiya. He initially held back (even though he's still very much fighting her) because he didn't want to truly harm a woman, but later let go and instantly creamed her.
