Soccer's "Zero"

Ego lays out the First Selection as a round-robin among five teams, where only the top two advance while the leading scorers of the losing sides can also survive, with fair-play deductions breaking ties. Team Z sorts its lineup, placing Isagi and Bachira up front, and faces Team X in a forty-five-minute clash inside Building Five.

The match immediately unravels as every Team Z player abandons his role to hunt goals for himself. Amid the chaos Shoei Baro, ranked a lowly 250th, seizes the ball, glides past defenders with heel flicks and nutmegs, and finishes coolly, proclaiming himself the king who treats the ball as a servant meant only to make him shine. Team X wisely rallies behind Baro, funneling passes to their leader and racking up goals as a unit while Team Z keeps bickering.

Watching Baro impose order on a formless game, Isagi grasps Ego's riddle: the chaos was zero, and Baro's decisive play turned it into one, a foundation a team can then multiply. In the closing minutes Isagi surprises even himself by passing to Kunigami for Team Z's lone goal in a 5-1 defeat, and Baro sneers that a striker who freezes before goal has no talent. After the match the team pieces together the lesson, that the striker creates the one and the other roles multiply it, and Ego confirms they are on the right path while warning that football demands individual weapons.

Ego explains the First Selection rules and the top-scorer survival bonus. Team Z's game collapses into a free-for-all as players chase personal goals. Baro dominates, scoring and declaring himself the king of the pitch, and Team X unites behind him to win comfortably. Isagi assists Kunigami for Team Z's only goal in a 5-1 loss. Afterward the team arrives at the zero-to-one insight, with Ego affirming their direction.
