This story (as do many others that I have done) will have more than just two categories as some are for references. This list down below should cover for the beginning; I will add in more references along the way as the story goes on

Main:

My Hero Academia
Fairy Tail

Secondary (still important):

Seven Deadly Sins
Sailor Moon (for additional characters)
Devil May Cry (for bits in details)
Kingdom Hearts (in bits)
Chrono Crusade (for important bits)

The "secondary" still plays the important roles despite not being the main centers of the story. I will add in more information as the story and many others will continue to make progress. I hope you all will enjoy this story and many more to come!
