Air Gear volume 4 collects volumes 10-12 in an omnibus format and features story and art by Oh!Great.

Ikki has officially made it in the world of Air Treck. After winning a big match against reivals Team Behemoth, Ikki and Team Kogarasumaru are the talk of the town... for better or worse. Fame brings a whole new set of challenges. Behemoth might be out of the picture, but now Ikki and his team have bigger fish to fry: overly-inflated egos, internet trolls, and legions of teams coming for their crown. Ikki and his riders might be on top of the world, but do they have what it takes to stay there?
