History
Geese is originally a God Eater working for a special group Asasoru. After defeating the Golden Susano'o, Geese and Marguerite escaped from Fenrir's control to live their lives freely despite being fugitives to Fenrir. Lindow Amamiya helped them by falsely reporting them as killed in action against the Golden Susano'o. However, Geese's P53 Bias Factor deficiency led them to seek asylum under Fenrir again in form of the passing Friar, and Marguerite was made a God Eater while Geese participated in a God Arc Soldier riding experiment to repay the favor because he did not have his God Arc. After his participation, Geese mysteriously disappeared which triggered a suspicious Marguerite into escaping from the Friar.
