@ Rain - First conflict ended when the corps realized the losses they got wouldn't be offset no matter how they won so they all signed a treaty. No one wants a war because the losses are too much no matter who wins.
It will definitely cause an uproar since it was hidden. Most likely everyone's gonna be scrambling to ground it and restrain it.
The high voice, permanent blush, and lack of personal space issues probably doesn't help Kyuukai's denial any. Lord know's what'll happen when he gets the maid outfit
Side note - Then I hope she doesn't get attached to Iris in the omake.
