She looks like Dulcinea, but with black eyes and colorless clothes. She helped Dulcinea defeat the Bloodwolf by giving her Sino’s amulet. When Dulcinea used the amulet to stop the Bloodwolf she and the other tulpas disappeared presumably killing them or sending them to the 'Beyond'. However Orange said that two tulpas still remain probably meaning there is an enemy stronger then the Bloodwolf and Sino knows about it.
She is a little bit sassy asking for a cup of coffee. She may look scary but she's pretty funny.
