-A bit long, heads up.

The past angst events have had the lead and bass players of the band being the 4stars, and the drummer being in the gacha. Meaning that the gacha cards we can expect are:

4star Aya, 4star Chisato, 3star Maya

and then the ranking rewards should be

3star Eve and 3star Hina.

and then the following angst events should be

4star Ran, 4star Himari, and 3 star Tomoe for the Afterglow event gacha, with 3stars of Tsugumi and Moca for ranking rewards.

and for harohapi, it should be

4star Kokoro, and 4star Hagumi, with a 3star Kanon in the gacha, with 3stars Kaoru and Misaki as ranking rewards.

but i might just be looking too much into this just trying to figure what cards might be what and ill be surprised if im right, which im probably not.

FINAL EDIT: A final edit to finish off the secondary stories and their cards! HHW and Afterglow did not follow the pattern after all! (mainly because it would be unfair to give Ran and Himari another pair of 4*s together for the Afterglow story~)

i would like to believe that they found out that i was onto them and they had to make me be wrong cause i would just be too powerful

anyways everyone that was just a theory and you shouldnt take guarantees from me on cards
