Miss Marcella Bellona

Miss Marcella Bellona is an elderly penpal that Celia keeps her fourth year. She has a cat named Nibbles, and reached out due to being a fan of the Fincastles.

Connections with Casimir
After writing to Celia all throughout the year, Miss Bellona finally writes that she would like to meet Celia and have tea on Miss Bellona's birthday, to share information she has on Celia's grandmother. Celia is rightfully cautious, but her desire to get out of the castle as well as know more about her family triumphs. To be sure she's who she says she is, Celia meets with her in Rio Plata, with all her friends carefully watching. With her identity verifyed there, Celia follows her to where Miss Bellona say she she has reserved a table for lunch. It turns out that she is a Desert Knight. Her real name is Heeba and she works for Casimir. It is the most successful capture that Casimir ever executes.
