After being unable to for so long, Naofumi finally gets to upgrade his party's classes. He then takes part in a meeting of the Four Cardinal Heroes, held under the guise of a celebratory banquet. There, he learns of the existence of a bonus stage, with increased XP earnings. Meanwhile, Raphtalia gets into a fight at the party.
the infighting between you heroes has 
prevented you from leveling up more.
إلّا أنّ النِّزاع بينكم أنتم الأبطال قد منعكم
من الترقِّي أكثر
so waren es doch Reibereien zwischen euch
Helden, die den Levelanstieg verhindert haben.
la disputa entre héroes
entorpeció su aumento de niveles.
la disputa entre héroes
entorpeció vuestro aumento de niveles.
mais il est sûr que vos querelles
è innegabile che le dispute tra voi Eroi
siano state deleterie al vostro avanzamento di livello.
mas sem dúvidas a rixa entre heróis
atrapalhou o seu aumento de nível.
но вражда между четвёркой
помешала Героям набрать высокий уровень.
