Perolina was a formerly famous mascot character, but after a boom, its fame faded and it was no longer popular outside of Arzenal. Jasmine acquired a supply of the merchandise that she sells in Jasmine Mall to the few remaining followers of the character.
Vivian is a fan of the character. She has posters in her and Salia's room, a drawing in the notebook with a list of the things that she wants, a stuffed Perolina doll, and even a Perolina drawing on the right shoulder of her Para-mail, AW-GSX232 (VV) Razor. She bought three small Perolina keychains for Ange, Hilda, and herself, yet Ange rejected the gift. (CROSS ANGE: "A Loner's Revolt")
During the 'Mermaid Festa', Ersha dressed up in a Perolina costume and gave out balloons to the children of the base. During a break, Ange used the same costume to avoid Emma Bronson after her call to Momoka Oginome, that Misty Rosenblum had wanted to speak with her. Ange "kidnapped" Misty who was later found gagged and tied up in the Perolina costume. (CROSS ANGE: "Bikini Escape")
