story excerpt from I hate ladybug:
Firstly, there was no connection to hawkmoth or a delay... it seemed that the second that the akuma made contact it started to turn her into the monster of her own emotions.
Secondly, this akuma moved far more sparaticly than all the others tiki had seen... as if the whole world's negativity challenged its sobriety. And lastly, the akuma didn't search out an object, it simply flew right into her chest.... her heart.
The little bug watched as Marinette was drowned in her own sadness, anger and self-hatred.
Black bubbles incasing her as she hit the ground.
