Stella no Mahou OVA

Tamaki's really excited about going to high school, but she's not sure what kind of club she wants to join… until she meets three girls who are making their own computer games! Remembering how she loved making board games when she was little, Tamaki takes the plunge and joins the group as their new artist. Now she, programmer Shiina, writer Ayame and composer Kayo are in a frantic race to finish their game in time to show at the big "doujin" conventions. Meeting their deadlines won't be easy, especially since Tamaki has to learn on the job and Aya keeps getting distracted writing steamy love scenes. But where there's a will there's a way, and with the help of a bunch of talented friends, they just might be able to make it in time!

A new year arrives as the school festival ends. The season has come as Kaou-kai members leave their jobs at the Kaou building. Each musical team prepares for the final stage, Graduation Ceremony, to show their thankfulness. After the incident at the school festival, the now-disbanded Team Ootori is disqualified from participating. In the midst of these events, Yuuta Hoshitani and the others make a decision…

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.

Bundled with the sixth single of the anime's μ's idol group.
