Brattysis Nia Nacci | Keeping A Secret Top

I should create a character named Nia Nacci, maybe a young genius or someone with a talent for math. The setting could be a place where math or puzzles are important, like a school for gifted students or a fictional town with a history of mathematicians. The conflict is about keeping a secret, maybe a hidden artifact or formula related to Fibonacci. The protagonist needs to outsmart others trying to steal the secret, using their knowledge of math.
