Isagi's team cinched a win due to the awakening of Barou as a villain on the field. To cause more chemical reactions in the fourth stage, they picked one player from the other team, who demonstrated ego to devour them during the game. In the meantime, Bachira and the Top 3 are looking for the next opponent. Rin sees through Bachira's "monster" during their training, which forces Bachira to face his own ego.
Become the one who chooses, 
not the one waiting to be chosen.
كُن الشّخص الّذي يختار، ليس
الشّخص الّذي ينتظر مَن يختاره
Sé el que escoge
y no el que espera que lo escojan.
Sé el que escoge
y no el que espera que lo escojan.
Te bats pas pour être choisi,
mais pour choisir les autres.
Non devi essere quello che viene scelto,
Torne-se aquele que escolhe e não aquele 
que fica esperando pra ser escolhido.
Стань тем, кто выбирает,
а не надеется, что его возьмут.
