~ Mirror World, the Supply House ~
Kazuo and Kaoru stepped through the door-shaped rent between the worlds and came once again into the empty cafeteria area.
"Three, at the moment. I'm told as your will gets stronger, you can summon even more, but I haven't been able to go higher than three at a time yet," his other self mused.
It was then that they heard Kitano's yell, muffled to incomprehensibility by the walls and distance between them. Apparently, time moved differently inside the music box room.
"I think we've been missed," Kaoru said, starting back toward the room with all the weapons, although a faint blush did burn her cheeks at the memory of what Kazuo had said when she'd led him away from the group. She raised a hand, hiding a cough to cover her embarrassment, and stood out of the way as she held open the door to the room the others were in. "Here..."
Inside the room, Satoko patted Taro's arm with a smile as the candy took its effect, then frowned softly at the rest of his reaction. She adjusted her glasses on the bridge of her nose and turned to the blind girl with a little sigh.
"I tried to explain this earlier, but you, collectively, were not very cooperative," she started, with all the annoyance and derision of a scientist whose theories had been completely ignored by the community as a whole. "To open the conduit between worlds, a link must be established within close proximity. In other words, two beings with the same potential must be in the same place, if you will, at the same time." She lifted a hand with one finger raised to forestall questions as she went on, adjusting her glasses again as she spoke. "If my theory is correct, certain corresponding members of this collective group will have similar potential--Personae--and certain other members will have different potentials, rendering them invalid for establishing the link between worlds. In summation, the only members of our retinue that have such an ability would be the girl you left behind and myself, and Kaoru and your Kazuo. I am sure that you will find the classification of Personae to be different in all other pairs of this group."
