When an airplane goes down in a plume of black smoke near their city, best friends Tokio and Azuma join the volunteer search and rescue team. But instead of a wreck of twisted metal, they discover that the plane suffered minimal damage and that over 200 of the passengers are still alive! With their services no longer needed, the friends head for home, but on the way, they run into an old enemy who has picked up some bizarre new powers and an obsession with destroying them. Now Tokio and Azuma only have one chance to make it out alive—by becoming the superpowered creatures known as choujin!

Being a superpowered creature isn’t all it’s cracked up to be. Tokio has to hide his transformation from his family and dodge a truancy charge at school, all while dealing with an increasing number of odd incidents happening around town!
