Episode 4 of Haruka’s Secret is out on pre-release from Moenigga through torrents. I got the torrent from here. It’s only available as a AVI file as far as I’m aware. But Moetaku will release a full lovely-fied version later on. The Moenigga release is for those of us who just can’t wait!! (Like meee!)
Check the Moetaku site to see how progress on ep 4 is going.
