Alya Césaire is Marinette's best friend who typically wears a plaid shirt and black glasses. She constantly helps Marinette with her problems, most of which pertain to Marinette attempting, and failing, to speak to Adrien; she is often seen encouraging and helping her to talk to him. She aspires to be a journalist and is in charge of the school blog. She is a big fan of superheroes and like her peers, is a massive fan of Ladybug; she even operates a fansite known as the Ladyblog, but like everyone else, is unaware of Marinette's superhero identity.
