Shizuka Furuya

The girls are personifications of firearms. Assault Rifles primarily. The story follows the FNC, M16A4, L85A2, and Sig 550. While the plot itself isn't deep or motivating, the series is filled with fun adventures and incredibly accurate facts regarding the various firearms.

Life in a small city needn't be boring. Not when your city is home to a host of deeply odd people. Granted some residents, like high-school buddies Mio and Yuko, are fairly normal. Yuko is a world-class space-case and Mio has an unusual mastery of wrestling and boxing, but... okay, so they're odd too. Together with fellow residents such as Nano, the frequently modified robot of five-year-old genius the Professor, talking cat Sakamoto (that's Sakamoto-san to you!), and their own friend, the poker-faced lunatic Mai, they lead provincial lives that are perfectly mundane and thoroughly bizarre.
