In Episode 28, Reo Mikage struggles with his desire to play alongside his former teammate Nagi Seishiro. Determined to prove his worth, Reo participates in a tryout to show that he is strong enough to stand by Nagi's side. Meanwhile, Isagi Yoichi reflects on his recent goal with his teammates Hiori and Nanase. During their conversation, Isagi realizes that he has begun processing information and acting at high speed like an experienced player, allowing him to keep up with top-tier players like Rin Itoshi and Ryusei Shidou.

As the second match of the tryout begins, the elite players showcase their extraordinary abilities. Reo notices that talents like Nagi, Rin, Shidou, and Yukimiya Kenyu are playing on a hyperdimensional level beyond his own skills. He feels overshadowed and decides to rely on his unique talent: copying the movements of other players. Using his "Chameleon" playstyle, Reo successfully replicates Yukimiya's spinning shot and scores a goal.

Despite this success, Isagi and Hiori point out that copied movements can only achieve up to 99% effectiveness compared to the originals. Reo acknowledges this limitation but remains determined to improve and push past his own boundaries. Meanwhile, football prodigy Itoshi Sae expresses his dissatisfaction with the current U20 team and reveals his intention to team up with a Blue Lock player for an upcoming match.
