I have no idea if the first two stories link together, but the next event looks to be a continuation of the 'Sky' events and the last time we had a part 3 to an event series...

Not including Backstage Pass, obviously, that's a special occasion. Could there be a full trained / 3+☆ set like with Noble Rose's part 3? I'd have to expect something momentous like what happened in that event for it to happen again... We'll find out tomorrow. Still standing that this is a part 3, even if the stories don't link like a series.

I guess with the official translations, they're the 'Skies' events.

Also, the SPECIAL beatmaps are for Hey-day Capriccio and Karma.
