Auto-battle nonsense game which, like all of these, draws out a fairly unnecessary story over an excruciating amount of time. You can tell exactly when the decision came down to stop supporting KH:UX because suddenly the pace accelerates to a somewhat acceptable level.

Even as a KH fan trying to keep track of all this shit, seriously, you just do not need this. It's more of a Coded than a Union Cross. Even if these characters show up later, they will be strangers to Sora and you will be introduced to them. You can just read about them on a wiki if you're that curious.
