Seele

Seele is an Estonian-born girl who suffers from split personality: one side is a fragile girl who cries at any small things, the other side is an extremely dangerous being who will stop at nothing to accomplish her goals. Lived in the same orphanage as Bronya, who acted as her big sister and protected her from harm; this led to Seele idolizing her big sister Bronya and becoming willing to do anything in her power to keep Bronya to herself.
