Ok, so the plot of Kingdom Hearts is very complicated. That is what it is mostly known for besides being a perfect place for Square Enix characters and Disney characters to meet. That being said, it has been a huge part of my life and I cannot wait for more games to come out. It is an important game series in my life and is my absolute number 1 favorite game of all time.
This book was written before Kingdom Hearts Union X, Dark Road, and 3 were finished. Don't worry, it will be updated to reflect these changes!
So, characters.
Sora, Riku, Kairi, Namine, Roxas, Xion, Lea, Isa, Demyx, Lauriam, Elena, and Braig will appear in their appearances from Kingdom Hearts 2.
Ventus, Terra, Aqua, and Vanitas will have their appearances based on Kingdom Hearts Birth By Sleep.
Young Xehanort's is from Dream Drop Distance.
Skuld, Ephemer, Brain, and Strelitiza is from Union X.
Ienzo is the only one who will have an appearance based on his Birth By Sleep Debut.
So, here is the class!
