She regularly visits the Touch & Go! cafe within GTO headquarters, interacting with main characters Ascoeur, Q-feuille, and Di-air. During chaotic events, she delivers common-sense commentary, acting as a grounded counterbalance to more eccentric personalities. Belle works alongside her partner Alisa, consistently exhibiting a calmer and more even-tempered disposition compared to Alisa's occasional irritability. Their dynamic establishes Belle as the straight man in their exchanges. Alisa's undisclosed wealth affords them access to exclusive experiences like a resort for affluent women, contrasting Belle's routine receptionist duties. Her core narrative role involves supplying pragmatic observations amid absurd or overwhelming situations.
