As someone who used to shoot competitively, seeing Hikari change her sights because she's shooting off-center hurts my soul. At least if you're outdoors and shooting real bullets you can convince yourself it's the wind, or the humidity, or the barometric pressure throwing things off, and changing your sights will help, but... sweetie, that's a light rifle. And you're indoors. I know how bad you want to, but it's not going to help. It never helps.
