The OVA features six separate stories revolving around the cast, some of which border on the bizarre; one of which is an MMORPG environment being played by Konata, Kagami, Tsukasa, and Nanako Kuroi, and another in which Kagami has a "suggestive" dream about Konata.

The stage is set on a moon of Planet Cray, "Aniversario." To develop the moon, Selca summons Aichi, Chrono and friends. A large undertaking by familiar vanguard characters!

The 11-year-old Miyamoto Rebecca becomes the new teacher of a classroom which is full of weirdos. Despite her cute looks she's a little beast and can be pretty sarcastic and offensive.
