Chronobug and Bunnyx race against time to uncover who exposed Marinette's secret as Ladybug; faced with a new villain wielding the Butterfly Miraculous, they must thwart disastrous timelines to save her legacy.

When a new villain steals the Miraculous from her, the future of the world is threatened. Marinette/Ladybug must join forces with Alix/Bunnyx to travel back in time and find out who the new villain is, why they are doing this and how to stop them from ending it all.

After getting a past version of the miraculous using Burrow, she used it to transform into Chronobug. A French teenage girl who briefly kept the Ladybug Miraculous after Marinette gave up to be Ladybug and put it in her bag in "Stoneheart", until Marinette took them back.

Marinette and you woke up to a bright light in the morning, when you investigate, you discover that someone else had made a wish, how is that possible you might wonder? To make situations worse, Marinette had mysteriously lost the Ladybug Miraculous, along with the Miraculous of the Black Cat. Then, a sudden portal like gateway opens behind you two, with Bunnix/Alix pulling you in.

The two of you work together with Alix to save the universe, trying and failing once every time. Marinette seemed to feel like giving up, but then her friend ((you)), had an idea.
