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.
I'll give in to this surge of excitement 
and face whoever stands in our way.
سأستسلم لموجة الحماس هذه
وأواجه أيّ شخص يعترض طريقنا
Ich werde mich der Aufregung hingeben
Me dejaré llevar por esta sensación
y aplastaré al que se ponga por delante.
Me dejaré llevar por esta sensación
y aplastaré al que se ponga por delante.
On a plus qu’à vous affronter
avec cette rage de vaincre.
Adesso mi abbandonerò a queste emozioni
Vou ceder a esse surto de animação e 
enfrentar qualquer um que entrar no nosso caminho.
Я доверюсь этому воодушевлению…
и брошу вам вызов!
