1) This is my third scan. Cover was not leveled. Scanned at 600dpi for cover, 300dpi for the rest of the pages. I've decided not to apply b&w adjustments, the original blueish tint seems fine. Not sure how to deal with the scan lines, if I figure it out I'll reupload this. I am also willing to put a bounty for anyone who can edit those issues for me (PM me for details).
2) Please support the artist. With my limited Japanese, this is the best I was able to find: http://www.toranoana.jp/mailorder/article/04/0030/17/31/040030173199.html (thanks to Mugi) - perhaps several people will buy this, despite the ridiculously overpriced shipping that plagues international orders from Japan. Unfortunately, as the Japanese are on average more backwards than the rest of the (developed) world when it comes to Internet business, I cannot direct you to a PayPal or a dedicated micro-donation button like Flattr. As always, I remain hopeful that one day Japanese mangaka will figure out that there's a vast population of fans overseas who are screaming "TAKE OUR MONEY", and adopt an internationally friendly micro-donation service. With that said, I want to do a little experiment: if this gallery was linked to a PyaPal-like micro-donation page where you could send any amount of money to the dojin author (not me, I repeat, to the Japanese author himself), how much would you send, if anything at all? 5 cents, 30 cents, a dollar...? FYI, this dojin was sold in Japan for around 2-4 bucks, IIRC.
3) I am willing to sponsor, through bounty system, a translation of anything I've scanned. If you'd like to TL this, PM me.
4) I am quite happy with this - good art, nice character selection. Would be nice if someone can upload part 1 (https://www.doujinshi.org/book/626667/NO-EXIT./), through the characters there seem to be a bit more boring (as in, featured more often in other works).
