NicoNico user Hihebi probably doesn't have any issues doing perfect runs on the Japanese rhythm game Hatsune Miku: Project Diva F, since he's able to play one of its songs using airsoft guns.
The song is Senbonzakura (Thousand Cherry Blossoms), one of the most popular Hatsune Miku tunes.

So this is kind of off topic, but aren't realistic looking guns supposed to have orange caps on them or something to signify they're not real so the people using them don't terrorize others and/or mistakenly get shot by cops?
