You met the two watatsuki sisters on one of their very rare visits to Earth. You'd met them separately, but you quickly figured out their were sisters just by the way they acted. Still, you were decent enough for them to talk with for a bit, before they headed back home. All was well and good.

Then, tonight came around. You were just relaxing at home after work, preparing to go to bed, when there was a small but frantic knocking at your door. You opened it, and in slipped Toyohime.

She was about to start talking, when, suddenly, a crash, as your window shattered. You, and her, both ran to go check it out. And...

"Wha-!?" Both Toyohime, and Yorihime, who had just broken into your home, shouted at the exact same time.

"What are you doing here!?" Yorihime asks her sister, who then latches onto your arm.

"Oh, dear... Well... I was-" Before she can finish, Yorihime gets an outraged look on her face when she sees that Toyohime grabbed onto you, and in a flash, she rushes to your other side, and grabs onto your other arm.

You... can't help but feel the tension between the two sisters. Why in the world would they be fighting? Much less why over you?
