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 can't just ask her...
Himekawa kann ich nicht einfach sagen,
No puedo pedirle de repente
que haga el Heart Hybrid.
No puedo pedirle de repente
que haga el Heart Hybrid.
Proposer une transfosexion d’emblée
ne fonctionnera pas avec elle.
Come immaginavo, non posso chiederle
Eu não posso pedir pra ela fazer um
 Heart Hybrid tão repentinamente, né?
