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.
There's a fight happening 
in the reception hall!
!ثمّة معركة تنشب في صالةِ الاستقبال
Anscheinend gibt’s
im Ballsaal eine Schlägerei!
¡Se están peleando!
¡Se están peleando!
Il y a une querelle à la réception !
Pare sia in corso un litigio
nella sala dei ricevimenti!
Parece que tá acontecendo
uma briga no salão!
Кажется… в зале драка!
