Yeah. It was the original submission when he's was asked to draw a series. It's been translated too iirc. One thing I really like about this is that the lovely BroCon Kasumi is far more involved. Wish he'd kept that in the final version.
That aside... Sexiest manga out there imo, better than ToLove Ru Darkness. Love the artist and that he draws official H pics of his characters. Kukuri hnnnggg!
Does anyone happen to know what the first hentai pilot chapter is called? I cannot find anything about it when I searh in English or Japanese on google.
