He was involved in the "Erobomb! (えろぼーん)" game in Japan project. (only for PC Windows, released in July 29, 2005). In fact, if you google the term "Muyedang" you'll find out he has made accounts on the internet with certain unique purposes..
He used to be affluent with his "deviantart.com" account, but he hasn't been active since 2005 apparently.
