Erina der Vogelweid was first introduced in God Eater Burst as a child, she is the younger sister of Eric der Vogelweid. She and her brother come from a wealthy family. Near the conclusion of the game, having gotten over her brother's death, she informs the player that she wants to become a God Eater, but asks The Protagonist to keep it a secret from her father. Her goal was realized in God Eater 2.
Although she was shown in TGS footage using an Assault Gun, she uses a Shotgun in the demo. This is evident from the Aragami Bullet she receives from Garm (Aragami Bullets conform to the gun-type of the recipient in GE2).
Like her brother, she has the Wrath of Revenge skill.
She addresses her God Arc by the name of Oscar.
Erina is the youngest God Eater to date arguably after Soma.
