Where's the Chibi Mikusan pool? This needs to be added. :( Also, seeing as this is 301, shouldn't post #446976 be added to the pool too, since it was labelled as #300 by Minami?
Could it be? A new chibi vocaloid-like character!! YAY!!! I can't wait to see what madness/cuteness is going to happen. I some how get the feeling that this new girl would not get along with Neru. Don't know why, bu it's just a feeling.
Those kanji are pronounced "Seion Suzu". 清音 means "an unvoiced sound", so she's probably going to be one of the silent types. (kind of an oxymoron for a Vocaloid, but... yeah.)
