This is an era of cosmic colonization where strength is measured by mecha, with various mecha clans dividing the world among themselves. Legend speaks of two most mysterious bloodlines in the universe: one is the "Mecha Alchemist Bloodline," capable of modifying super mecha through arcane algorithms; the other is the "Mecha Battle Soul Bloodline," able to command the most elite mecha from ancient ruins. In an era long after these bloodlines had faded into oblivion, a street thug named Yan Xiaokai found himself swept into the rivalries of the mecha clans after accidentally rescuing a damsel in distress.
