Blue Lock: Episode Nagi manga volume 2 features story and art by Kota Sannomiya and is a prequel series to Blue Lock.

Roused by Ego's speech at orientation, Reo jumped head-first into the Blue Lock program…and dragged Nagi in kicking and screaming. Now the real work begins as Ego announces their next test, the “first selection.” In this round-robin battle between the members of wing five, it's not just about being on the winning team; the top scorers also get a goal bonus. Let the clash of massive egos begin!
