I can't tell the difference between these two and I don't care to look any closer... Feel free to change the parent/child relationship to whichever one is the higher quality image.
artist name is 乱漫. I searched far and wide across the abyss that is the internet and could NOT find any blogs or websites about this artist. The only lead was in COMIC Megastore H 2009-01. There was no furigana for the name at all.
it's funny really in that all of a sudden people figured out the artist name. pics from this artist have been floating around this site for months if not more
