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?
You always used to follow me around 
and call me Yurishia-senpai, right?
Siempre me seguías a todos lados
llamándome Yurishia-senpai, ¿no?
Siempre me seguías a todos lados
llamándome Yurishia-senpai, ¿no?
Tu ne me lâchais pas d’une semelle, 
dans le passé…
Un tempo mi seguivi dappertutto
 e dicevi sempre "Yurishia, signore", ricordi?
Você andava para todo lado me 
chamando de Yurishia-senpai, não era?
