Guro artist who also delves into exhibitionism and humiliation themes. Also hangs out on several Japanese Guro PaintBBSes.
Apparently "reformed" since his original creation Nagatoro-san debuted, and no longer does guro works.
Updates very slowly (once every 1-3 months) fueling rumors that he is a pen-name for a well known manga-ka.
Somewhat infamous for creating 1 shots that look like they should be part of a series, then never creating part 2, causing no end of complaining from newbies on the various *chan sites.
Artist name: "774" or 七七四 (Nanashi)
Circle name: 774ハウス (774 house / nanashi house)
