Well. That was a shock, to say the least. The sudden appearance of her other invitee from not below, but above, earned a startled blink from Mitsuya, then a broad smile. Apparently she hadn't been mistaken in calling him here.

"Ito-kun!" she chirped cheerfully, sounding for all the world as though he hadn't just descended from the roof, of all places. "I'm so glad you could make it. If you'll wait there just a moment, I'll get us in--"

On the last word, the window she'd been wrenching at finally gave way, opening enough for them to wriggle inside... but something was definitely off. As the other two made their respective entrances, Mitsuya was able to survey a room that was suddenly and rather distressingly empty. Granted, there was magic involved, so for all she knew, it could've grown legs and wandered off, but... hmm, there were an awful lot of disturbances in the dust...

(Mod check~)
