m.3.3.w is a speedsub group, but their quality is very good as speedsubbers go. They did a good job on School Days, and they sometimes release higher quality versions later, as they did here.

I liked the first episode, it's always good to have a series you don't have to think too much about to enjoy. Fanservice series never fail with that. I see the second girl, blue hair and red eyes, is voiced by Miyuki Sawashiro. I love her voice, it oozes sexiness, and a bit of pretentiousness.
