Time ability related emblem

Well, I think I'd say personality, though it also might be chosen ability

I don't have a specific idea on what it should be, but I guess I could say maybe weapon? If I was a magical girl, my weapon would be kinda like homura or mami, except I would want to have rifles and steal explosives lol

Grenade launcher?

Probably.

Do ya know any more explosives? I'll look up some explosives so I'll have an idea.
