You know... after Kwamibuster, a lot of things in Feast make sense. Of course, we have Bannanoir, but it also sort of explains Fu's decision to make Marinette the Guardian despite her young age. Marinette was super OP in Kwamibuster and proved that she was able to handle a LOT of miraculouses/ kwamis at the same time, plus knew how to utilize them perfectly. It's still weird how Fu was a victim of the whole "forced to be a Guardian despite being a literal child" thing yet still did the same thing to Marinette, but after Kwamibuster, his decision seems less sudden and unexpected.
