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.
