've never met him in real life, wouldn't know what his face looks like
Sadly enough, ranou doesn't seem to use his pixiv to advertise his doujins; the similarities to his style are very apparent, though, so I'm tagging him but keeping the request up. Someone else help confirm?
A somewhat late note (after rediscovering this image): I've changed the artist tag from ranou to ryuuta_(msxtr) because this is a page from "Angel's stroke 50" doujin, which is credited to the later artist. But artstile seems to be distinct from other Ryuuta's art, so I'm not completely sure.
Edit: Changed it back to ranou because the art style really looks more like his work.
