Episode 6: I'm Sorry

With Isagi now the pivot of the side, Team Z braces for Team W and the Wanima brothers, Keisuke and Junichi, whose wordless combination play tore Baro's team apart. Iemon insists the answer is to pry the twins apart. Kuon, oddly slow to leave the bathroom, pitches a plan built around three compatible strikers rotating every thirty minutes and dubs it Southern All Stars, a name the others promptly mock.

From kickoff the twins recognize Chigiri as their former teammate and taunt him about his fragile leg, but Isagi steals the ball and tells him the past means nothing, that he only sees the Chigiri of Team Z. Kuon heads home the opener, then piles on two more for a first-half hat-trick, and Team Z carries a 3-0 cushion into the break. In the second half the twins drift into midfield and start clawing goals back, and Isagi notices the opposition suddenly reading every one of Team Z's weapons.

Catching a sly smile on Kuon and then watching him deliberately fluff a header, Isagi confronts him. The Wanima brothers cheerfully confirm the truth: during his fake bathroom break Kuon slipped away to hand Team W every strategy, weapon, and weakness. He lays out his cold arithmetic, trading the win and the intel for the freedom to bag three goals, making himself Team Z's top scorer so that he alone can advance while the rest wash out.

Isagi rallies Chigiri against the twins' provocations, and Kuon's hat-trick builds a 3-0 lead before the twins' midfield surge erases it. Kuon's missed header exposes his betrayal, which the Wanima brothers confirm outright. Kuon announces he now plays for Team W, turning the match into twelve against ten, and reminds Isagi that the top scorer of an eliminated team still moves on to the next selection. He thanks Isagi for being naive enough to believe bonds and teamwork could win, and Team W presses its numerical edge to take the lead.

The episode aired on November 13, 2022 in the First Selection Arc, adapting chapters 16 through 18. It opens with Chaos ga Kiwamaru and closes on WINNER, following Episode 5 and leading into Episode 7. Its Additional Time short, Traitor, splits the squad into a bread faction led by Raichi and a rice faction led by Bachira, each arguing the superior breakfast; when Kuon says he prefers cornflakes with milk, both sides brand him a traitor and try to draft him.
