All the way down from the town to the island… From a certain Strife’s arms to a silver head’s!... From Final 幻想 VII to Kingdom Hearts! 你 x Riku/ 你 x Cloud(implied) A Final Fantasy/Kingdom Hearts one-shot crossover.
Based loosely on my own theory that the man that Sora met in the "secret place" in KH1 was actually a play on time and his identity was Riku as Xehanort's heartless. Something to think about.
