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.
My right leg is both a 
ticking clock and a partner.
ساقي اليُمنى هي قنبلة موقوتة وشريك في نفس الوقت
Mein rechtes Bein ist
sowohl eine tickende Zeitbombe
Mi pierna derecha es un compañero
y una bomba de relojería.
Mi pierna derecha es un compañero
y una bomba de relojería.
Ce genou est mon plus grand allié,
mais c’est une bombe à retardement.
La mia fidata compagna e allo stesso tempo
una specie di bomba a orologeria.
Minha perna direita é uma bomba-relógio 
e minha parceira ao mesmo tempo.
Моя правая нога —
мне и верный помощник… и бомба.
