Alya Césaire is Marinette's best friend. She is also the only admin of the Ladyblog and head of the school blog. Alya is rather energetic, passionate, funny, confident, adventurous, yet down to earth. When it comes to anything involving Ladybug and Cat Noir, she easily becomes very excited and has a single goal of updating her blog quickly. Alya doesn't like being undermined or doubted by others, especially when it comes to her work. If someone points out something wrong to her, she is too stubborn to admit they are right. Though her research is generally right when she takes her time, Alya tends to jump to conclusions. Alya is extremely loyal, supportive, helpful, and sometimes pushy, such as when she goes out of her way to encourage and (sometimes literally) push Marinette into spending time with Adrien. She is also very stubborn when it comes to doing things her way.
