Noël-sensei instructs at the Santa Claus Academy, an organization tasked with cultivating future ambassadors of Christmas joy. Exclusively featured in the OVA adaptation, she summons Mai back to resume her training, though the precise rationale behind this recall remains unspecified. Her duties center on rigidly enforcing institutional regulations, specifically mandating the detachment between apprentices and their assigned Santas.

During exchanges with Mai, she maintains formal but circuitous communication, leaving room for Mai to misconstrue the directive’s criticality or underlying intent. This dynamic introduces an external catalyst that strains Mai’s mission, heightening the conflict between pursuing personal attachments or adhering to her ordained role. The character’s backstory, personal motivations, and potential evolution remain unexplored within canonical materials, with no documented appearances in supplementary media or alternate adaptations.
