Animation:
The animation quality is on par with the main series, though you're going to get some really wacky outfits and (very ecchi) mechs? There's a serious effort to parody other series, which I'll let the viewed discover for him/herself, sometimes embedded in the visuals. The series' only absolution is the liberal airtime given to Sena. As in the main series, expect significant ecchi - though this one goes pretty close to full H.
Sound:
You have the same OP as the parent series and the VA cast is identical as well. They add a new ED sung by the cast, which has an annoyingly-repetitive main melody.
Story:
We find our loners club on a typical day where they decide to take turns writing a single short story. This soon turns into everyone's individual fantasy involving Kodaka as they churn out the most in-cohesive story ever written. While certain parts are amusing, the overall plot is quite lame and contributes absolutely nothing to the overall series. I'll admit I'm a bit biased as I was hoping for a bit more relevance given the less-than-stellar ending to the parent series.
Character:
While each character does get air time, their interactions are as you would expect from the main series. Their interactions are still fun to watch, but I think the series missed a great opportunity to give some more background on Rika/Yukimura.
Value:
Other than for base entertainment and/or fan service, this doesn't add much to the parent franchise, for dedicated fans of the main show only.
