Mother Goose
About
The joint leader of both the East Side of the Magic Academy and Valhalla along with her partner, Orochi Kusanagi. She is the human form of the Sacred Treasure type Magical Heritage, Gungnir.
Mother Goose is primarily benevolent and bases the organization of Valhalla to ultimately save the world. While generous on most occasions, Mother Goose is highly demanding from her subordinates as to move advance their goals further. Matching her benevolent goals, she is generally kind and merciful toward her enemies and has the demeanor of a high-class lady.
In the light of her goals, Mother Goose is just as, if not, even more bloodthirsty than Orochi is and is willing to do anything by any cost if it means getting closer to remaking the world. However, she would still offer a chance for anyone to yield before facing her.
