Gunsmith Cats is a manga by Kenichi Sonoda. It originally ran in the magazine Kodansha’s Afternoon from 1991 to 1997. A sequel to the series ran int he same magazine from 2004 to 2008. While the original series had 8 volumes (9 in English), the sequel only had 5. An OVA anime was also adapted from 1995 to 1996 and only had 3 episodes. Takeshi Mori directed the OVA.
The series follows a 19 year old bounty hunter named Rally and her partner Minnie. Rally is a great marksman with almost every firearm known to man. Minnie happens to be an explosive expert. Misty Brown later joins the team as an expert lock picker. The three own a shop where they sell and repair firearms while also hunting bounties and making enemies.
Why I chose this anime: I love this short little OVA of Gunsmith Cats. It sums up their relationship and job pretty well. I only wish there was a series adapted.
