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.
What we need to do to make sure none 
of these sacrifices were in vain
لكن ما علينا فعله للحرص على 
ألا تذهب هذه التّضحيات سدى
Wir müssen sicherstellen,
dass niemand vergebens stirbt
Lo que debemos hacer es asegurarnos
de que sus sacrificios no fueran en vano
Lo que debemos hacer es asegurarnos de
que esos sacrificios no sean en vano
Notre devoir consiste
à remporter cette lutte
L'unica cosa che possiamo fare per assicurarci
che questi sacrifici non siano stati vani
E agora, para garantir que esses
sacrifícios não foram em vão,
А нам остаётся лишь сделать всё, чтобы
гибель людей не оказалась напрасной.
