Here's the Ikesen Official Visual Fanbook! It's mainly about the vita game but it also contains things from the mobile game and the ***下载/download/otomedream/ダウンロード*** (and I think the manga too?). I bought the ebook version. I originally posted this on another forum but I don't authorize ANY reupload, please tell me if you see this elsewhere. Please tell me if the link doesn't work anymore^^
