Because you bear Entis inside of you

What !?

You may think that you have no powers in you ・・・

But is that really so?

Now listen ! I have never used magic in my entire life !

And I already told you that I have no idea how to do that either ! ! !

What you cannot use is the Entis that Roussell can use and it is because only Roussell can use it that you cannot !

My head is spinning already
