I need some /k/ worthy animu, like upotte or girls und panzer.
Boku no Gunslinger girl
This isn't actually an anime that /k/ would actually love, but, something just occurred to me...
Unless I'm completely mixing up anime in my tired mind, the characters in Angel Beats practice remarkable gun safety. As in, better-than-plenty-of-real-people-let-alone-anime-characters levels of gun safety...which is weird, considering all the characters died and went to purgatory as children and young teens. In a nation where getting a rifle is about as easy as becoming Prime Minister and handguns are banned outright.
