I was skimming around youtube and found this Utau called Buttnose. Her voice sounds so sad yet so beautiful at he same time T^T

Toeto - Originally sung by Megurnine Luka

Hello/How are you? - originally sung by Hatusne Miku

Last Night, Good Night - also originally sung by Hatsune Miku
This song is probably my favorite from buttnose. She is singing in soft append :3)
