Nanana (七奈) was an artist that drew a lot of gay UY stuff and then Yakuza stuff, but then deleted a good percentage of her Pixiv gallery after saying something along the lines of "I've drawn everything I've wanted to." The things that are deliberately not in this gallery are doujinshi samples and a collection of yonkomas from "人も街も宇宙も!" I may be missing something, please let me know if I am. Most of the stuff is non-H, the only pornographic stuff is on 157. Can't tag it, but it has Ataru getting fucked by tentacles if you need to know. There's also a breastfeeding thing on 158, but it can be interpreted as non-sexual. Apologies for the low quality of 175-181.
