Soo.....guess what?
Iris made a huge mistake
Ok.......We need to clarify something!
Soo......This idea popped into my mind.
I was chilling in my bed and I was thinking of "Who killed Mephisto?......"
And I had 4 options:
-Iris
-Praxina
-Gramorr
-Mephisto( su!c!de )
And it is not Praxina's fault that Mephisto died and the same with Mephisto.
So we have two options:
-Iris
-Gramorr
And now, here is the theory:
Iris said:" You, MONSTER!" and she activated her Shanilla......
She activated the Shanilla with anger, and because we all know that a light-cristal magic user uses his power with positive emotions.
It is like an MHA quote
Soo.....still thinking
Iris or Gramorr "killed" Mephisto.
Maybe both?
My job is not done here.
Sayonara!
