It ain't easy being the savior of Mankind when you're still in high school, but Hoichi Kano will have to make due. Luckily, he has a super-cool integrated gunsuit at his disposal, just the ticket to take on the monstrous mechanical horrors of a pesky group of all-powerful alien invaders. But eventually, fire must be fought with fire, and luckily Earth may have the biggest beat-stick in the playground, the massive, anti-matter-powered robot, Exaxxion. And of course, all it needs is someone crazy enough to pilot it. Oh, Hoichi...
ガンスミスキャッツ -  Gun Smith Cats
Girls, guns, and grenades! Meet Rally Vincent and Minnie May. By day, they work at the Chicago gun shop that they own. By night (or holidays or week-ends), they moonlight as a pair of bounty hunters called the Gunsmith Cats. Rally is an expert at firearms, being able to judge the condition of a gun with a glance, and being an expert marksman. Minnie May is younger and less disciplined; and has an absolute fascination with explosives. Lots of explosives. Especially big ones. Together, they form an unbeatable team; much to the consternation of the local ATF bureau. Set in the city of Chicago, this action-adventure series features a lot of gunfights, car chases, and general mayhem.
