As compared to the bouncy, slightly airheaded Matilda and the cool, rather detached Kanna, Marion seems somewhere in between. Though the least is known about her out of the trio, Marion has shown to be quiet and unemotional. However, she is still a child at heart, as seen where she was instantly intrigued by the prospect of Shroom and Moss's ice cream maker. Marion would appear to balance the serious Kanna and the carefree Matilda, and cares about them both. However, as seen when Matilda gave her a hug, Marion seems to have some difficulty with returning affection shown her.
