@Chizan How is he supposed to know a little girl that is very shy, is his Middle aged friend with no speaking issues? The only evidence he would have is that his friend say he was nearby. The gun doesn't help at all since all it seems to be is a threat.
Why does she have a fake gun? Clearly underage, so wouldn't be allowed to buy one. If it's fake, where is the orange tip? Otherwise she'd have to buy one illegally(Fake without orange tip). Eh whatever it's not real
Actually depending on the country the Airgun may or may not have the orange tip. Also it is possible to order them online. At least that's how it is in my country, not sure about japan though
AFAIK orange-tipped airguns/pellet guns are only for US sales. For every other country there's no requirement for them. Here in the Philippines I can buy a pellet gun that looks identical to the real thing.
