Sakurai Tomoki has settled into his life with two angeloids, Ikaros and Nymph, and is thoroughly enjoying himself. However, he continues to have peculiar dreams that leave him perplexed. In an attempt to uncover the source of these strange occurrences, Tomoki enlists the help of all his friends.
Nymph creates a device that allows individuals but not angeloids to enter other people's dreams. Initially, the gadget malfunctions, but eventually they manage to access what was supposed to be Tomoki's dream. However, upon closer inspection, they discover something is amiss with it.
Later on, a meteor falls from the sky near the large cherry blossom tree where Tomoki first encountered Ikaros. A well-endowed blonde angeloid armed with a massive sword emerges from the wreckage and sets out in search of Tomoki.
