"...So...uhm.... who are you...? Nyeh...." Asked Himiko, still feeling dazed, sitting on your bed. She was very short, only 4'11.

"Me...? I'm [Y/N]." You replied, still feeling a bit shocked.

"...He's Mikado Sannoji, I'm Himiko Yumeno. He doesn't talk much. Maybe if I blew off half his mask he would." She sighed, hugging one of the pillows she'd spawned a minute earlier.

Mikado was writing something, again.
"I don't care."

"Okay then... Nyeh!" Himiko fires a bullet from nowhere at Mikado's face, which shatters half the mask. This reveals a very emo and dead inside face. It occurs to you both Mikado for some reason can't show expression on at least the left side of his face.... weird.

"At least I can now talk properly."  You'd hear him speak for the first time, which was a little surprising but you didn't mind the quick change. "Anyway, the more important thing is... What should we do with you?"

Himiko considered this for seemingly a while.
"...Nyeh.... that's a good question.... since Duo was trying to kill them, that proves they aren't sided with Duo.... should we tell [Y/N] what's going on?"

"...I don't see why not."
