Marinette and Alya- friend

Alya and Marinette are best friends, often hanging out with each other or helping each other out with something. While amused by Marinette's inability to act normally around Adrien, Alya encourages her to talk and do things with or for him, and motivates Marinette to never give up. Alya is also very forgiving and accepting of Marinette's flaws, such as when Marinette accidentally deletes Alya's video of Ladybug (which resulted in the theft of Alya's phone for several hours), she immediately tells Marinette that it was no big deal, though she is disappointed Marinette had not told her sooner. Despite considering Marinette a ditz sometimes and perplexed by her constant disappearances, Alya loyally stands by her, and she appreciates Marinette's kindness.

Alya is a devoted ladybug fan and has a special alert on her phone to never miss ladybug in action. Alya is eager to find out Ladybug's true identity to help her in the future. Her search for Ladybug's identity is relentless, one time mistaking Chloé, a cosplayer, for being Ladybug. As Lady Wifi, her frustration with her search intensifies, complaining how heroes should not hide their identities.
