Oh dear god she made him cry.

So Emillia did the only thing she can think off, taking out her handkerchief and wiping his tears off his face.

"There, there. Its alright." She smiled. "Nice to meet you, Mike."

She hoped sincerely that he didn't break down completely and start bawling out loud, because that would be rather embarrassing. This person was a weapon, if the transforming arm was of any indication, and showed plenty of potential. Emillia would dearly like to partner with this one, but as she didn't know how Shibusen chose their pairs, she supposed anyone they paired her up with would be alright. 

Extending a hand to Mike, Emilia gestured towards the masses of people, still milling about nervously because of the Witch still there. "Come, the opening ceremony is still not over. I'm not sure when it ends, or how it will end, but we can't leave now, not when the Principal haven't given his speech yet." If he had a speech that was. She wasn't entirely sure if he even wants to give a speech, and just end the night with a wave then leave.
