Unit N07 gets a lucky break; they're given a forced leave of absence for 60 days. They decide to visit a tropical resort to camouflage their attempt to figure out a game plan for Mismis' astral crest. However, fate has something else in store for them.

The Empire's experimental weapon, Object, goes after Sisbell. It also detects Mismis' astral energy. Iska and his team must fight Object to save Sisbell and to stop it from uncovering Mismis' secret. However, it seems Object has gone through an upgrade.
