Himekawa is a guilt-stricken by her failure to protect the citizens as they boarded the Tokyo megafloat.  When a mysterious radio signal is picked up by Atraxia, she leaps at the change to perhaps finally save a civilian.  But when Amaterasu arrives at the source of the signal, they find an enemy from another world, and one deeply connected to Himekawa's past.
I'll wipe out the enemy with 
my Immoral Weapon if I have to.
Wenn es drauf ankommt, werde ich sie
mit meiner Unsittlichkeitsrüstung vernichten.
Si hace falta, acabaré con el enemigo
con mi Armamento Inmoral.
Si hace falta, acabaré con el enemigo
con mi Armamento Inmoral.
S’il le faut, j’utiliserai
l’arme immorale contre l’ennemi.
Se sarà necessario, spazzerò via il nemico
 con la mia Arma Immorale.
Eu acaberei com todos os inimigos 
usando minha Arma Imoral, se precisar.
