Vahn was one of the first there, mostly to give back to any survivors of the bombs that might not be able to make it to the bakery.  He had always the feeling that he could have done more, saved more people or even been more help to people that were wounded at the time.  He's been using his suit and semblance to help the search for other survivors and protecting some of the crew from any falling debris.

"Yo!" He said as he checks the amount he had on him.  He hasn't done much to fill his pocket but he pulls out enough for about half a dozen loaves of bread.  "... sorry if it isn't a lot, but how much can I get with this?"

Vahn jumps and looks at the cheery. "Huh? Oh ah... Thank you?"  He takes the cheery and offers a handshake with an armored gauntlet. "I'm Vahn and I'm here for the case too.  I hope we work well together."  He looks at the cheery and then looks around, At least I'm in a police department, best case I get a cheery.  Worst case... well I'll probably be okay. He eats it.

Looks at the buildings that has been damaged by the explosions.  "I wish I did, for now I'm making sure I can help anyone in need.  Start to head to any signs of survivors trying to get out of the destruction before looking back at Camille.  "Stay safe, Camille.  If you find anything, please let me know.  I want to find the bastards that did this.

Vahn looks at the destruction as he runs, shouts and tries to direct anyone to an area that hasn't been effected by the explosions.   "Keep calm!  Keep your distance from the buildings!  Head East!"    He repeated while ignoring his own words.

"I can't do this alone... " He thought as he place two fingers on the left side of his headgear.  He had a feeling communications would be flooded but he had to do something.  While trying to get in contact with the authorities, he notice someone limping with a sword as her support.  He ends the call and offer her his shoulders.  "Come on, we have to go."

Shocked and confused at what had just happened a few blocks away from him, Vahn quickly toss his coat and rush towards the exploding buildings.  His helmet develops around his head while he search for survivors.  "What the hell is going on?" Is all that he can think of while loading a canister of water dust in his revolver and having a wind one at the ready in the other hand.

Vahn looks at the hologram with interest.   Even though Atlus did catch his eyes more as a kid, he sees how problematic they can be in the future if all they do is make weapons.  He tries his best to listen to the presentation seeing that Prometheus seems to deal in medical needs.

Don't know if he counts since he isn't a student just trained by a retired Huntsman but can Vahn join in?

History. Sorry about the errors, I'll look in to the History. 

Semblance.  I wanted to include the crushing on only human-sized robots because I didn't want the power to be too OP and the factor of other's Aura and heavily armored beasts/robots kinda made me iffy.  How about the crush effect stays but depending on the size and amount of enemies/ armor/ aura it starts to decay?  Still damaging but doesn't fully takes out the target while giving Vahn a choice to continue crushing but leaving him with no aura or pulling out just in case.  Will him being able to move the bubble be a problem?  If not, then yes as long as he keeps his hand up towards it and moves his arm to where he wants it to go.  If it's around him, it moves as fast as he can walk.

Weapon.  I wanted to do something different with a Rwby character and I haven't seen anyone with armor as their weapon.  Of course I didn't want to go full Ironman but since he is at a disadvantage with his Semblance and the illness, I think it balance it out a little.  And yes I'm willing to add that it can start to break with more stress and damage inflicted to it if that might be an issue.
