Kizuna is declared the captain of the megafloat's defense squad: the Amaterasu.  For his mission, he's sent to an uninhabited island to scan for needed resources.  But what was supposed to be a safe mission turns dangerous when a miscalculation sends them right into a Magitech ambush.  Kizuna's Eros gear is dangerously underpowered, and Yurishia is running desperately low on energy...
It's no exaggeration to say that the fate 
of humanity rests on your shoulders.
Das Schicksal der Menschheit
hängt von dir ab.
No exagero si digo que el destino
de la humanidad recae sobre ti.
No exagero si digo que el destino
de la humanidad depende de ti.
L’avenir de l’espèce humaine 
repose sur tes épaules !
Il destino dell'intera umanità è nelle tue mani
 e non si tratta di un'esagerazione.
Não é exagero algum dizer que o futuro
 da humanidade está em suas mãos.
