When Maria first presented herself to
Shido, she appeared to be nothing more than a curious girl who simply wanted to know the definition of "love" at first.
Maria observed Shido's interaction with the Spirits throughout the game, and not only did she understood the meaning of "love" through her observation, but her true personality slowly resurfaced. Her personality seemed to be a combination of
Tohka and
Origami altogether. She can easily become interested in common things found in our daily lives, with Shido introducing hot buns to her as an example of this. Unlike Tohka, however, she is as knowledgeable as Origami due to having access to the Fraxinus database.
