12ID-082, released by TMA in 2004, is about a cosplay club at a school. The students dress up as characters who were popular at that time, from Clannad's Nagisa to Fate/stay night's Saber.
This is part of a series that started with 2003's BL-040. Although the DVD cover advertises multi-angle functionality (as was reasonably common in those days), this is unfortunately unavailable when purchasing the video digitally.
Mizuki Haruka is the featured actress of this video. Starring alongside her is a fairly large cast, including Takai Nami, Hidaka Maria and Hidaka Yuria.
To be honest, I struggled to follow the plot, but all manner of crazy antics occurred in the school between the students and teachers… and that's before we even get to the sex scenes.
On the one hand, it's pretty cool that this video features cosplays of many popular characters, and the costumes were decent enough. However, the video otherwise did not stand out to me as a compelling piece of entertainment.
Score: 6/10
