Found this artist during my art exploring for CITY R-18 art. Discovered them too late as most of their fanworks are nuked from all of their socials. Nowadays only does original/professional work judging by their present day Twitter page.

Unusually, this is the same phenomenon that happens to any artist who does CITY/Nichijou lewds.
Most of artists' traces all get removed at some point in time. Reasonings behind these occurrences are unknown.

Only sharing their R-18 works specifically. Surviving art shown seem to be made around 2021-2024.
Feel free to share any remains/archives or more information about this artist if I get anything wrong.
