The artist puts all of his R-18 works only on this site, which is kind of a mess to access for some reason. Half the time I try to authenticate with Twitter, the website just completely refuses to connect for me. However, I really love his works as a fellow Idol Club fan, and his infatuation with Riko in particular really resonates with me. The man has a fine appreciation for underboob. To keep an archive for myself and get his art to some more folks, I've compiled everything from the site (not from his Twitter or Pixiv), which also happens to be pretty much nothing but R-18 Idol Club works.
Unfortunately, the site seems to restrain images to 900px, but at least they're pngs. What can ya do.
