Collete Farandole

Collette Farandole is a beastgirl who attends the magical academy in the city-state of Ariadne and is training to be a mage knight. She is the first person whom Yue encounters after being teleported, and was directly responsible for Yue's total memory loss. This was due to an accidental collision with Yue while riding her broom and practicing a memory-erasing spell. Feeling responsible for her, (and not wanting to be punished for Yue's amnesia), Collette offers to watch over Yue and help her with her studies at the academy.

Like the class president, Collette is a Nagi Springfield fanatic and possesses a large collection of souvenirs and merchandise. Her fanclub member number is 96077. She competed as Yue's partner for a chance to go to the tournament finals. During the race, Collette and Yue make a good showing and even getting ahead of Emily Sevensheep and her partner. At that point, she discovers that the empty card that she had found when Yue first arrived was actually her Pactio Card.
