So, this is by far the best Sekai dojin, not that there's much competition. But hey, it's full color and has yuri in it, which fits the series the most, so really, it's good stuff :) We got the TL for it few months ago, but it took us a while to find a good scan (replacing https://e-hentai.org/g/755053/b68b4f5482/). I think it was worth it. Expect the TL to hit the galleries in the few days.
If you know of any Sekai works we are missing PM me. We got more then Mugi has already (http://www.doujinshi.org/browse/parody/4488/Wanna-be-the-Strongest-in-the-World/)

EHCOVE is looking for a scanner in Japan who can order dojins from Japanese stores like nagomiweb.jp and scan them for me. Willing to pay commission fee on top of covering purchase and delivery costs (and the scanner keeps the books). Can pay through PayPal/Neteller. PM me if interested.
