She is the first friend of Anos, and the sister of Sasha.
She is not a real person and is only a copy of Sasha (her 'sister').
On her 15th birthday she is supposed to disappear since she doesn't exist and merge with Sasha in order to become a stronger being, but Anos makes it to where they can both keep living.
In episode 13 it is shown that she and Sasha can fuse into one being.
