Currently looking for:

1. Works by Nagi (ナギ) from the old Japanese 2次元敵女画像掲示板, and the removed Emeraude doujin from his Pixiv.

2. Author of black and white Naruto doujin, see thread and attached pic.

3. Name of recently deleted Chinese Pixiv artist.
Black and white comics featuring assassin, kunoichi, wuxia characters, and other female villainess. Works include: an assassin is pushed into a metal shredder, an assassin tries to kill her target on a lakeside boardwalk, and an kunoichi on a rooftop tries to kill a samurai/daimyo.

Many Thanks
