Have you even seen her in action!?
For my evidence, I submit her six victims of serious slime-rape:

Papi, Cerea, Miia, Rachnee, Kii, and Draco!

Suu has, with little to no provocation, molested all of the girls mentioned!

In addition, it has been alluded to that Rachnee has gotten slimy more than once with Suu!

Given, Suu usually doesn’t have a scary bone in her body (or any bones, for that matter), but she does have the capability to become scary at any given moment.

Therefore:

IT IS NOT HERESY! SUU CAN AND HAS SWITCHED FROM BEING CUTE TO TERRIFYING IN A MATTER OF SECONDS!

I rest my case.
(I’m so sorry, but I’ve wanted to do one of these Phoenix comments for a long time now.)
