Shigetaka Kurita's voice synth avatar was unveiled a while ago after the conclusion of the voting and contest through niconico seiga. The name of the character is Shigetaka Maron, Kurita's well-known niconico alias. In response to Kurita becoming the name of the character, his niconico username has changed to his real name しげたか くりた
Sadly, the archer Maron with the spirit of Kenzaki Mesuo didn't win. Lol. But it did win the runner-up.
Funbo, illustrator of the winning design, made a comic about the character. Funbo is also known for making talk sprites for these characters contributed to the commons, which I think helped the popularity of the design quite a lot.
Basically Zundamon sees Maron thinking Maron is a normal pretty older sister-type, tries to pick Maron up by inviting him to play Mushi King, and is shocked when Maron responds in a manly voice that his name is "Kurita" to which Zundamon is shaken to their core, realizing who it is and then the famous "niconico douga headquarters" image explodes. Classic.
