In a world ruled by magical powers, great warriors, and adventurers, Elliot Herit is an ordinary young man, born without any special abilities. He dreams of becoming the greatest adventurer of all, but he is constantly rejected and looked down upon by others. No spell, no technique sets him apart from the other people in this chivalrous and magical world.

However, his determination and his desire to prove his worth are stronger than anything.

When faced with a life-or-death situation, Elliot encounters a strange phenomenon: through a burst of music, he enters an intense trance, during which his physical abilities increase dramatically. It's not a pact with a spirit nor a bestowed magical power, but a mysterious bond between music and his own hidden potential.
