Gustave gives in to his burning anger toward the Seven Light Faith and unleashes Heaven's Flames, L'age Soliel.
The city of Dormundt panics at the sudden attack, yet Tsukasa remains completely calm. He had already anticipated all of it, and was confident they could all weather the attack if they did what was required of them.
So following Tsukasa's emergency manual, Domundt manages to avoid the worst case scenario. However, the Heaven's Flames aren't stopping. The fire spirits unleashed by the spell are compelled to continue their attack until the city burns to the ground.
Faced with a predicament even their missiles couldn't stop, the world's strongest swordsman, Ichijou Aoi, rises to the challenge.
There's no reason for me 
not to believe in that courage.
لا سبب يدفعني لعدم الإيمان 
.بتلك الشّجاعة
Es gibt keinen Grund für mich,
diesem Mut nicht zu vertrauen.
No tengo por qué no creer en ese valor.
No tengo por qué no creer en ese valor.
Je n’ai aucune raison
de douter de ton courage.
Non ho motivo per non credere in un tale coraggio.
Não há motivos para eu não
acreditar na sua coragem.
Поэтому я верю твоей храбрости.
