To translate from Otaku-san's excited 'nyo'ing, the series was Leave It To Piyoko, a spin-off of the very popular Di Gi Charat anime (which in turn was a massive tie-in with a cute company mascot). While Piyoko seems relatively unpopular in the west there was a time where you couldn't go to a convention without seeing dozens of people cosplaying the series, and a lot of silly, fluffy series since have borrowed from it, so I'd have expected it to be more well known even if the character I picked was not ;_;
As a piece of trivia, Piyoko also briefly appears in Cromartie High School, for a UK anime connection.
Anyway, let's see what comes up next!
