While you were resting in the Gehenna's infirmary after sustaining some gunshots. Satsuki, suddenly came out of nowhere through the curtains that surrounds your infirmary bed, she closes it and smirks in a naughty way as she made her way over to you.

"Well, Sensei~ Got yourself into a cross fire~?"

She said, before getting onto the bed as well, sitting on your lap as she pulls out a pocket watch in order to attempt to hypnotize you, doing so while keeping a naughty smirk. Seems like she was waiting for you to be injured so she can hypnotize you easier.
