Heaven

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.

After his mother takes him to a faith healer, aspiring musician Sebastian finds community at Heaven – but must cut all ties with his past.

Tomoki has another dream where the mysterious angel warns him of another Angeloid and after revealing the information to his friends, Nymph suggests they visit his dream via Dive Game which enables them to visit humans' dreams. The group, consisting of Tomoki, Sugata, Mikako and Suhara, leave into the dream to find themselves confronted with each other's dreams and an embarrassing revelation for Suhara. Ultimately, they are unable to visit Tomoki's dream and instead land on a bizarre world with a pillar with illegible words and hibernating evergreen trees. They return with more questions than answers and Sugata finally remembers a forgotten memory a year past when Ikaros first fell onto the Earth and winesses Astraea's arrival.

Tomoki, much to his irritation and confusion, finds himself aroused by the antics of Ikaros and Nymph. This disturbs him greatly so he leaves for the mountains to train in the Zen monastery. At the same time, Astraea, the new angeloid lands at the monastery to dispatch Tomoki while Sugata informs the rest about her. Nymph and Ikaros ignore the threat calling Astaea an 'idiot' and leave Tomoki alone who himself is finding trouble ridding himself of his 'earthly desires'. Later, Sugata discovers Astraea and learns of the threat to Tomoki's life and more information on Synapse, the world where Angeloids come from.

After unexpectedly divulging information of her assignment, Astraea attempts to attack Sugata to keep her secret safe. Unfortunately, she falls into the hands of Mikako, who upon seeing the gullible nature of the new Angeloid, fools her into joining a wrestling match at the local festival. Much like last time, Mikako entices Tomoki to join by putting up a prize of ten million yen and a chance to bathe with her family's geisha. Nymph wrestles with her emotions after losing her wings and master and finds herself yearning for a new one, Tomoki being her new candidate.
