In a future where the world of mythological creatures and humans has fused, the balance of the universe is constantly threatened by cosmic forces and time manipulation. Ancient creatures, once trapped in parallel worlds, have had their minds and powers fused with humans, creating a new hybrid race with supernatural abilities.

Kaelen Viraud, a young prodigy with a sharp mind and exceptional abilities, is one of the brightest students at the Stellar Academy, an elite institution training young humans to control their fusion with mythological creatures. However, Kaelen harbors a huge secret: he is the host of Quasarion, a cosmic creature born from the collision of the universe's earliest moments. Quasarion embodies the power of space, and its potential is limitless.
