[Birbs? - Snowball Fight]
BIFF! Ahhh!! Powder of cold and wet hit Rein and it's just terrible, causing him to nearly stumble just from the unexpected shock of it. He looks around for the guilty party with whom to lecture and/or punish. There's two people throwing snowballs and he doesn't know who did it, so he's just going to have to go off on them both. He reaches into his jacket and pulls out a long rifled gun.
This particular gun has some kind of feeder on top that Rein puts snow into and the assembly appears to be made of plastic blues and reds. The barrel is huge and within moments fires out a snowball at Mishnehel and a second one at Omiko with the not particularly remarkable force of something you might expect from a medium quality foam dart gun. These birbs brought snowballs to a snowball gun fight. Or wait, is it Rein who brought the gun to a snowball fight? Sounds like everyone's guilty.
