After their defeat by Grabel, Amaterasu needs a new weapon to protect Ataraxia: the Connective Hybrid.  To use it, Kizuna will have to perform the climax hybrid with two girls at once! He picks Yurishia and Scarlet, hoping to defuse the tension between them.  Will the pleasure be enough to cause them to reunite?  And can they retake Guam, and eventually Japan, from the Batlantis empire?
The double love Kizuna 
feels for both of them,
Die Liebe von Kizuna für beide
wird verdoppelt
El amor doble
que Kizuna sienta por ambas
El doble amor
que Kizuna sienta por ambas
Elle réclame deux fois plus d’amour 
pour votre partenaire,
L'amore che Kizuna prova per entrambe
O sentimento de amor que 
Kizuna sente por ambas as garotas
