Alya is a rather energetic and passionate, yet down to earth and smart. She is extremely loyal, supportive, and helpful, like going out of her way to encourage and (sometimes literally) push Marinette into spending time with Adrien. Her cleverness and foresight have come in handy many times. After Marinette thinks she accidentally lost a video of Ladybug on Alya's cellphone, Alya explains that she had already posted the video on her blog, expecting something to go wrong when she showed Marinette the video. From thoroughly observing Ladybug and Cat Noir while in action, Alya has figured out the basics of the superhero's work, like breaking the akumatized object to stop the villain. She doesn't like being undermined or doubted by others, especially when it comes to her work.
