As Isagi analyzes his new play-style with his team, Reo Mikage's match begins when he is forced to team up with his former friend and ally Nagi and take up the top 6 while proving himself on the field.

Seeing how incompatible Rin and Shidou are, Isagi hopes to take advantage of it. However, his physical abilities are not enough to get him where he needs to be. Then, Hiori suggests that Isagi does the thinking "on reflex."

Isagi is chosen as Team A1 along with Nanase and Hiori to play against Team B1, which includes Karasu, Otoya, and Chigiri. While Isagi struggles to find a way into the game, Chigiri and Hiori demonstrate their worth.
