Venus wars. Volume 1 - Yoshikazu Yashuhiko

It's 2083 A.D. Humanity has inhabited Venus for only eighty years, but already full-scale war threatens our precarious hold on the planet. Colonial forces battle each other for power and territory while the Terran government looks on warily, ready to intervene. High-powered Octopus supertanks clash with super-charged, one-ton Battlebikes in awesome displays of mechanized combat and cataclysmic destruction. Ken Seno, daredevil cyclist, rides into danger, unafraid to die. But if he falls, so does the last hope for life on Venus!
