All I can say is wow. (Not literally) But I can also say that this is one of the best adaptations from game to graphic novel at hand.
It starts off with Sora thinking about what's happening to his friends; Riku and Kairi. He then finds a castle named “Castle Oblivion”, and sets foot into it not knowing what's in store for him. Along the way he meets a mysterious man in a hood who will not reveal his identity. He gives Sora a card and disappears, leaving Sora and his pals; Goofy, Donald and Jimminy Cricket, in confusion. They then proceed through a door that leads to somewhere that will bring back memories…
Now what I can say is that this is worth any amount of money for anyone who likes the Kingdom Hearts universe. I rate it a perfect 5/5.
