So, after 2 years of not producing any anime, Studio Gonzo is set to produce Nyanpire. Based on a popular doujin by "yukiusa," the story follows a black cat who was abandoned and left to starve. However, just before the cat's life was to be extinguished, a vampire emerged from the darkness and gave it blood. Now, "Nyanpire" lives as a seemingly ordinary house cat raised by a human girl.
While it may not be a hit show for us, The Gothic World of Nyanpire is apparently relatively popular in Japan, spawning tons of cute vampire cat merchandise.
It's scheduled to air July 6th, as a part of the Summer 2011 anime season.
Takahiro Yoshimatsu, the character designer for Trigun is both the director and character designer for this series.
