Three elements, one goal: deliver the package at any cost.

Keita, Masamuno, and Todakari aren't just space travelers. They're three old friends who make a living as couriers, taking on jobs that no one else dares to touch. One commands the elements, another is as fast as lightning, and the third is a cyborg with an unbeatable body. When a mysterious package ends up in their hands, they become the target of the most dangerous thing the galaxy has to offer. Can they deliver the shipment before they're turned into space dust?
