Kazuki Yamato, A.K.A. Yōgan Shōnen or Lava Boy, leads an enviable life in some circles. Drag racer by day, alchemy drug dealer by night. He's on a mission to test his powers and scare his competitors into submission, but his devil-may-care attitude earns him more than he expects.
His ability to transmute into a super lava being on command comes in handy… until he’s caught and extracted by an infamous organization known as Global Cornerstone that's known for recruiting and experimenting on powered people.
Unbeknownst to them, he doesn’t give up that easily.
After their kidnapping attempt goes wrong, he comes back with a vengeance, and a team of vigilantes, who will stop at nothing to bring down the corrupt organization and its coconspirators that's responsible for their abdication.
