Rita standing there speechless, not able to wrap her head around what Alex just said.
If he just said he had beaten Jake in a brawl, She though still had a hard time believing it but it would have at least been reasonable.
Maybe male S-ranks are not as invincible as the female ones, It is not sexist to say it, It is just a simple fact.
However, what did Alex say? He sang him to death? There is no doubt he has a divine singing talent but there is no way it is to a degree where it can even kill people.
How can it even work? By her logic it is possible to put someone in illusion, putting them in a trance but that should be a limit.
But if Alex said it, then he definitely had done so, There is that unexplainable trust she has for him.
So she just couldn't help but ask him about his origin. There is no way any normal huwomen can do things he does, Not to mention he is a man.
