Sweetheart and her daughter, Misa, protected their base with their powers of restoration and resurrection, only to be ambushed by space hunters. The mother's divine power was stolen, and she was imprisoned, while Misa fought her way out and sought refuge alone at the Asuka Squad headquarters.

In every simulated battle, she secretly memorized the hunters' tactical weaknesses—the fire of revenge remained burning, waiting only for the moment the blade was drawn.
