She hand him a letter.

Letter: Dear Yn, if thats what you go these days. I need you to repay me the favor from the 30's. I want you to look after her and show her around the ropes  to survive as a normal person. I'm busy on my end taking care of a school full of mutant controlling there powers. Protect her. By the way-

She takes her boots off without a care in the world. 

Yn: Your room is in there. I'm taking a nap in the couch.

After a while of taking a nap, the girl flips over the couch while Yn sleeping.

Yn: What the hell...

Girl: Get up!

Yn: Noisy one are ye?

Girl: What are you going to do with me?

The girl then pops out a blade from her foot up to his throat. "Calm down.." he replied

The girl engage in a fight with him, but quickly reacts to her moves.

Yn: Fast, but sloppy.

The girl begins to sniff and looks out of the window.

Yn: You're an odddd.......... Shit! You go hide in the back and don't do any unnecessary action.  I'll call you once things get settle got it. Now hide!
