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.
Because you're so obsessed 
with something that childish,
،لأنّك مهووس بشيء طفوليّ سخيف
Weil du von etwas so Kindischem
besessen bist,
Como estás obsesionado
con algo tan infantil,
Como estás obsesionado
con algo tan infantil,
C’est à cause
de tes fantasmes de gamin
È perché hai in testa certa roba da bambini
Você fica aí obcecado com 
algo tão infantil e isso
Ты и играешь-то слабо
и трусливо из-за того…
