After the events on Sora no Otoshimono, Nymph now longs for Tomoki's orders and for him to become her master. Ikaros continues to enable her master's wishes for perverted action. Hilarity ensues as the gang go to a pool park and Tomoki's machinations reach a new high.
Hiyori’s a sweet, shy girl who’s ready to bloom and reveal a big secret: she’s totally infatuated with Tomoki! She joins the New World Discovery Club and starts bonding with Ikaros, Nymph, and the gang – until a sudden, tragic accident changes everything. It seems Hiyori has a deeper – and more dangerous – link to the Angeloids than anyone suspected!
Beautiful and otherworldly Ikaros’ connection with Tomoki is deeper than she originally thought. Now she’s starting to feel empty and confused—with new emotions she’s not had much experience with. How will she pick up the pieces after what comes next?
