*I got this idea from @thunder_roses's Shinra x Reader story! (I hope you don't mind me using the idea). Please go check out their stories!
I also put this extra at the beginning of the book so it didn't get in the way of the chapters
For now, I'm just doing opening 1, but I'll most likely make more
1) In the scene in the beginning when Asta is doing crunches, you can be partially seen sitting near him with your knees tucked into your chest
2) When Asta starts to chase after Yuno flying on the broom, you get up and start following him a couple seconds later
3) In the scene where Yuno is floating above Asta using his magic watching him fall, you can be seen on Yuno's spell yelling at him for not catching Asta
4) Shortly after that scene going into the main chorus with Magna, Noelle and Asta riding Crazy Cyclone, you're sitting behind Asta with your hands on his shoulders
Sorry that this one is so short, but there isn't many spots where you could be in
