14.
Nagisa is twelve and a weapon is pointing at their neck.
It's a real weapon too. It's not the fake ones that they've smelled from person to person over years and years. From kitchen to body from body to bag, from store to kitchen. And it looks heavy, and it must be because it can't cut. It's not close enough to their neck to draw any blood.
Nagisa has yet to figure out if magical boys like them bleed for real or if it's something else. They've never checked their injuries enough to tell. They're not sure it's worth it.
Still, Nagisa isn't afraid. They don't really know why. But maybe it's the way the girl in front of him is shaking so much. They feel more of a threat from the way they keep trying to be and doing things they don't seem to realize they're doing, rather than actually being able to cut.
And that, unfortunately causes the problem.
"Stay back!" she orders. "Give me your cubes!"
Nagisa doesn't quite know how to respond to this, lips quirking unbidden and hand closed over their Soul Gem.
They can fail plenty else, but not this.
"Nagisa."
Now. They panic.
