Nogizaka Haruka no Himitsu - (乃木坂春香の秘密, lit. Haruka Nogizaka's Secret)
Original Run - July 3, 2008 – September 25, 2008, 12 Episodes
Just finished it and I think its worth watching, I give 4.5 stars out of 5 Story is good but I can they can do better on the graphics.
They used Shakugan no Shana's cosplay and music and the maid cosplay Dokuro-chan. http://www.youtube.com/watch?v=UQqG8OzWTNk
And also I like the way they did the op starts off with Photoshop. Any chance on the playlist?
