Assisting Ladybug and Chat Noir: Next Gen AU

This is going to be based off the Bridgette and Felix Ladybug and Chat Noir because I want to take creative liberties, Some of this AU is going to be somewhat different but a few similarities. If you have a question, ask and I will answer.
Chance and Lucky are the children of Felix and Bridgette Agreste. They seem interested in Ladybug and Chat Noir. Lucky loves the idea of being adored and having powers. Chance is interested in the kwamis, the powers, the history, etc. All of a sudden there seems to be a new villain in town. A chat noir is already picked. Lucky is picked as Ladybug however she doesn't seem to know how to do anything even WITH Tikki and Master Fu's help. It seems it's up to him to help Ladybug and Chat Noir.
