After graduating high school, Elio King, an aspiring superhero with ludicrous martial arts and great power, begins his journey alongside his friend, Reggie, as they set out to take an exam that'll determine whether or not they're qualified to be recruited as superheroes. As they work to become heroes, they're on their own in the world of Kosmesen, a giant planet where all solid surfaces in the Solar System of our universe are merged together as one super continent with various races, all of which are far more advanced in evolution than Earth's people. As the two begin their journey, they'll come across many friends and allies, adversaries, and boundless landscapes and locations, learning about the history of the world, taking down forces of evil, and working together to achieve each other's goals as superheroes.
