Aoi ' Santa ' Kurashiki

Santa is sitting on his lower bunk in the barracks, looking through the backpack that holds his starter kit. He's pretty annoyed as he flips through it and it shows on his face as his mouth twists and his eyes narrow. There's a pink, metallic looking watch object on his left wrist that he pulls at occasionally, looking even more annoyed every single time it doesn't come off. When he starts pulling objects out of the backpack and trying to use them to pry off the so called watch, it's obvious that this is the source of his annoyance: he wants it off and he wants it off now. He knows there are only two ways to remove it, he knows this, but he's trying anyway. He never expected to actually be trapped somewhere without the ability to remove it at will.

The fact he's concerned with this over their surroundings and the situation suggests it must be pretty damn important.
