As we know 5th, 4th and 3rd gens are now 4 member ones. It also goes in reverse order. Don't you find it strange?

We would only use JP gens.

When Aloe graduated there were 5 gens excluding gamers. There is a reason why we are excluding them.
Thus probability of her graduating was 1/25

5th gen loses member, we cut them from equation.

With Kiryu Coco the probability goes to 1/20 as we removed 5th gen from equation. Same probability goes for Rushia as we know have 6th gen.

Thus probability of this order is 1/10000 which rounds to about 0.01%.

There is no way this wasn't already preplanned beforehand. The reason they gone 543 and not 123 is basically Sora. She is their face.

Between Aloes graduation and Coco's here was 304 day span. While between Kiryu's retirement and Rushia's firing 238 days. That's 66 day difference.

My prediction that Ayame's graduation would be anounced on August 15 with pretix of health problems.
