While Others Pilot Mechs, You Become Ultraman

When the universe collapses and every Ultraman vanishes, Leo—the last of his kind—crash-lands on Blue Star with humanity's final hope. On this world, teenagers awaken giant mechs through entrance exams, piloting steel titans into battle. But Leo? He doesn't need a machine. As Blue Star teeters on the brink of annihilation, a crimson giant rises—wielding an energy chainsaw, firing disintegration rays, and channeling the power of a solar core. They call him a weapon, not a living being. They're wrong. He's the ultimate warrior, and his name is Leo.
