YES! Someone actually uploaded it, thank you! I thought we would have to wait ages like las time to see Kawase's latest masterpiece, but his return after years without making a Doujin is finally here, and his first full-color one at that! SAO Incest is Wincest the most when he's in charge.
Thanks a lot for sharing, looking forward to the translation hopefully soon!
I would suggest to check out all of Kawase's SAO doujins starting from the first one, then, he has been making the best KiriSugu ones for literally the last decade.
