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?
