Today, I was browsing Pixiv, when I came across this drawing: http://www.pixiv.net/member_illust.php?mode=medium&illust_id=9998546
The character's name is Sou 77, with 77 being his model number. His homepage seems to be another fake Crypton website [note that it's not the same page the most recent Vipperloid, Tei, was posted on]: http://crvpton.client.jp/
Even though Sou 77 isn't drawn in KEI style like Tei, Teto, Ruko, and Ritsu, the website seems to be enough to imply that he's another joke, especially considering his feminine appearence...
Does anybody know anything about him?
