I didn't say I've seen both the Epilogue and the Secret Ending, I meant that both will be released not long after the actual game's release for the rest of the world, lol. If I've seen both, I would've mentioned how it was like by now, but neither are released nor had they been leaked yet.
0.2 was a story set during the events of the first Kingdom Hearts via Aqua's point of view and then later from Mickey's memory as he retells that encounter to Riku and Kairi before setting off to rescue Aqua which will be one of the obvious points of Kingdom Hearts 3 as everyone has known since the Secret Ending of Birth By Sleep and in Dream Drop Distance, LONG before 0.2 was even heard or thought of.
