ユウちゃん, Yuu-chan (Yu, the ghost girl) from Puyo Puyo series.
Trigger words are:
Yuuchan, ghost costume, ghost hoodie, ghost tail, aqua hair, green hair, blue eyes
じゃじゃ〜ん！ Testament and resurrection speak of the same. Deo Vindice
*Tip: using 'ghost hood' and 'white ribbon' without using the word hoodie makes it more likely it will reproduce her original clothes (even the hood alone, if prompted right. Use 'ghost hood with white ribbon', for example) correctly. I had not known this previously
