Happens twice in the same chapter, when we see what Kyon did to intimidate Mori after the 12 Yakuza. He smashed through a skylight over thirty feet in the air, landed unharmed, made a gratuitous display of telekinesis, handed a spy over to the Organization, and blackmailed her into letting Koizumi become a liaison. He then jumps back out through said skylight.
Koizumi, after being Demoted to Extra for much of the fic, gets his when he uses his Esper powers outside of Closed Space to utterly dismantle a laser-slinging future inter-dimensional death bot.
Koizumi gets another one in Open Battle Chapter 1. He single-handedly saves the day when Kyon and Yuki are surrounded by murderous Yakuza, and are completely depowered.
