In Episode 27, Team A plays a critical match where the internal dynamics greatly influence the game. Isagi observes a rift between teammates Rin and Shidou, whose contrasting styles—Rin's strategic precision and Shidou's raw instinct—lead to clashes on the field. Isagi senses an opportunity and decides to exploit the discord between the two for the team's benefit.

With the support of Nanase and Hiori, Isagi attempts to unite the team by fostering collaboration between Rin and Shidou. However, his physical abilities still lag behind his tactical understanding. A turning point occurs when Hiori advises Isagi to "think reflexively" to keep up with the top players. Isagi adopts this approach and begins to act more on instinct than deliberation.

In a decisive moment, Isagi utilizes his newly discovered reflexive thinking and scores a crucial goal by outmaneuvering both Rin and Shidou. This feat not only secures victory for Team A but also marks a personal breakthrough for Isagi, even if he doesn’t fully understand how he managed it.

The episode ends with the announcement that Reo is joining Team C and looks forward to reuniting with Nagi. In a lighter closing scene, Otoya entertains Chigiri and Karasu with his so-called "ninja arts," which humorously turn out to be playful, flirtatious pranks.
