Stranded in space, with humanity's governments forsaking them, and within the ship anger, agitation and fear setting in, Kouji tries his best to maintain a semblance of order and peace in a time of crisis. But with fighting his own brother Yuki, dealing with his feelings for the beautiful Uranian aristocrat Fina S. Shinozaki, trying to avoid Aoi, and seeing the strange apparition of a girl in pink wandering the halls, will Kouji be able to help until the Ryvius reaches safety, or will he lose all that's dear to him in the process?
