Alya Dies AU

What if one day, Marinette lost Alya to the akuma she was fighting. Lately Hawk Moth's akumatized victims are getting stronger and much more deadly, and some civilians have been hurt badly because of them. So one day, Ladybug and Chat Noir are fighting the latest victim who is the toughest one they have to beat. Alya is there trying to get videos and pictures for her blog and Marinette notices her there and knows she could get hurt. She turns her attention to Alya and ignores the akuma for the time being. The akuma notices that Ladybug is going for Alya and get to her before Ladybug does and kills her so Ladybug can focus on her. Ladybug of course just sees Alya get hurt, not knowing she's dead and she screams out and tries to go to her friend but the akuma stops her so Ladybug beats the shit out of the akuma and hurried to Alya but she's not breathing and so Marinette uses her spell to clean up the mess but it doesn't work on people and Marinette is just a mess and can't handle it and Alya is now gone and this is just how I imagined things happening a little after Alya's death...
