Olga
She seems to be copying someone. Sounds a bit like Russian female rock singers. But I could expect this from her. Some years ago I was interviewing her and she turned out to have more than the single cute side of a pink fairy. A rebellious, a bit punk side with a bottle of beer is also present in her, and I cannot say I don't like it.
One more thing I like about Olga is that she is a person without age. Same as Lena, the other girl from Fleur.
