Sagume's the only character without torn clothes, so "return of ripped clothes" is kind of a misnomer. Well, Junko too, but probably because he just didn't bother making one for Extra.

predictions
- Unconnected story: Latest VFiS chapter might be somewhat related?
- Focused on gameplay/resources: Probably both, being bonus options and pieces
- Team system: bonus options are assists
(- Enemies bleed season items to fill up gauge)
(- At full gauge get that season's bonus options)
I'm noticing that, considering ways to increase point value besides graze, in Aya's screenshot it looks like there might be faith items. But there certainly aren't a lot of them when ZUN only has an extra 130 and 190 in the other screenshots. Also notice that Aya's screenshot is near the beginning of the stage, Reimu is near the end, and Marisa is at the end. Reimu seems to have full gauge and Autumn, Marisa has full gauge and Winter. Does that suggest the season progression just starts with Spring? Could Reimu switch before the end of stage? Have Reimu and Marisa gained bombs or has Aya just managed to use three right at the beginning?
