Gunsmith Cats: Burst manga omnibus volume 1 features story and art by Kenichi Sonoda.

In Gunsmith Cats Burst Omnibus Volume 1, Rally and ace transporter Bean Bandit find themselves well outside city limits - and deep in the heart of Texas! After Bean's own vehicle is swiped, Rally hires Bean to get her and her bounty back all the way back to Chicago in a rental car... except it turns out it only had half a tank, and pretty soon Bean's got to push! The desperate situation turns still more dire when they seek sanctuary at a remote motel far off the interstate, and some Mob hitmen on their trail check in... but this is the Wild West, and the Monroe Inn is run by an old-fashioned grandma who packs a Winchester rifle!
