I just realized something.

Let's list the power-ups Issei has gotten throughout the series.


 * Balance Breaker (BxB)


 * Cardinal Crimson Promotion (CxC)


 * Diabolos Dragon (DxD)

And now let's list the "speculated" power-ups.


 * AxA


 * ExE

Do we remember Issei's primary source for his power-ups?....... It's Boobs.

And this is my realization....... The power-ups are Breast Sizes!!

Order of Breast Sizes: A, B, C, D, E, etc.

Issei's power-ups increase in scale and power in order of Breast Size.

I don't know what power-up Issei got that AxA could represent, but I still stand by my theory.
