"You're no longer in my possession."

Become a wasted puppet, just thrown away by the one who created you, Ei. She threw you and Scara away as puppets who were no longer in her grasp, as if she didn't need you anymore.

Ei left you both, dumped you in a place called Tatarasuna without even looking back at you. Scara, who somehow looks worrying, he's your big bro, and you're his little sibling.
