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...
When the tide goes out,
that island increases in size
Während der Ebbe
wird die Insel größer
Cuando baja la marea,
la isla aumenta su tamaño
Cuando baja la marea,
la isla aumenta su tamaño
À marée basse, 
la superficie de l’île s’agrandit,
Quando la marea si ritira
 l'isola diventa molto più grande,
Quando a maré abaixa, aquela
 ilha aumenta de tamanho
