This was an okay addition to KHIII. While it did flesh out some of the ending story, it does so in a rather confusing way. I got it, but only after watching a youtube explanation. Ultimately my major complaint is that it lacks much game play. I'd say half of the "play time" was actually watching cut scenes. When you aren't watching cut scenes its just a typical KH end game boss rush (my least favorite part of any entry). The additional end game content is also bananas hard. For a game that I never died while playing on standard I can't even pretend to fight the first of 13 extra bosses. It truly is wild.

This is what I want from KH3. There are still some issues as the game edges towards too easy for the bulk of the dlc, and the game as a whole still faces issues with low difficulty. However, this story shines in ways the original release didn't always and the added story almost always feel interesting and engaging. Moreso than the emotional hits of the main game the dlc really pushes the emotional beats. This feels like the culmination that KH3 promised. I do wish the game cut a few of the refights (and cutscenes of said refights) that you don't get to play as someone else as they feel kind of bland and i wish there was a more effective way to take a file into the data battles/Yozora because it kind of encourages you to grind to 100 before the DLC starts properly. Small annoyances aside I really love the added story and especially love the data battles. Yozora is maybe a bit exhausting of a fight for just how long it is but for a final secret boss I get it.

This DLC for KH3 is a great way to explain the main story ending even more, and has beautiful additions from another point of view. Aside from clearing up the ending better, there is the Limitcut episode with 13 Data Boss Battles...

Now each one of these battles is so difficult, you need to be prepared and level yourself up, and also unlock the Ultima Keyblade, other than that, you're going to struggle since these bosses can only be damaged at certain windows, so most of the time you're blocking and dodging, and waiting for the opportunity to strike, the Hardest Data Boss is Data Xaehanort, and Xion...

After you beat all 13 hard bosses, you unlock "Yozoro" which is probably the most difficult boss I have ever fought, he is so fast and agile, and bombards you with all kinds of attacks, this is why watching guides is important. The Link Summon Ariel carries throughout this fight so well, but you still need to recover your MP, Dodge, Parry, and pray to Kingdom Hearts for good luck. It took me about 20 attempts to beat this boss. And the dude looks like a mixture of Sasuke and Riku, or bootleg Kaneki.
