She's with What?

When they got upstairs, Yuuma saw Miss Kim holding a bowl of water and rushing toward the bathroom. Wait, was it not Miss Kim and Rina who are in trouble? She looks absolutely fine! I think the system should have been integrated properly with the way she's moving around freely! But who is the one in trouble then!? 

Miss Kim immediately stopped once she saw Yuuma and she sighed in relief!

"Yuuma, come on. We don't know what happened to Rin. She just fainted when they were clearing a floor! I think she's sick but her fever isn't going down at all! We don't know what to do!"

Miss Kim didn't even bat an eye at Dyana and she dragged Yuuma over to the room where Rina was sitting beside the bed Rin was lying in! There was some sort of light coming out of Rina's hand and covering Rin and Yuuma guessed it was an ability from her system. At least they really integrated the systems properly. That was good.

But what happened to Rin. She's sweating like crazy!
