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.
And now the flames of my wrath
 shall immolate you, down to your very souls!
!والآن، فلتلتهمكم نيران غضبي وتبتلع أرواحكم
Und nun sollen die Flammen meines Zorns
euch bis zur Seele niederbrennen!
La flamme de ma colère calcinera tout,
jusqu’à votre âme !
E ora, le fiamme della mia ira
ridurranno in cenere persino la vostra anima!
E agora as chamas da minha fúria
irão queimar até mesmo suas almas!
А потому моя пылающая ярость
обратит в пепел каждого из вас!
