I have seen the first two season of SAO but there is a cutscene in Re:Fragment introducting the characters but, I do not recognize the black hair female character being character from the sky and falling to the ground where Kritio catch her.

In the wiki there is the floor cleaning part of Re:Fragment. How do I access that?

Is there any other requirments? So, I do not become confused.
