I believe I’ve highlighted Pixiv artist Naruto on this blog once before, but I didn’t show the full gamut of their Rumarin sketches, probably because I didn’t know clicking on the image takes you to a slideshow. In any case, you get everything from sleepy Rumarin clutching his pillow, to cross-dressing Rumarin looking like a charming maid.
Find all 12 of Naruto’s sketches here. Because as Numeriku points out, one does not stop tagging Rumarin, or making Rumarin related posts. I was in hostage situation once, and the robber said, “It’s Rumarin or your life,” and given banning Rumarin content was unacceptable, I now post as an undead corpse.
