30,000 years ago, sentient beings from the
Dark World, called
Remnants, invaded Earth hoping to make it their new home. The
Guardians of Earth fended off the attacks of the Remnants by sacrificing
the Key, a boy named
Kairen, to seal the gate for another 30,000 years. In the epic battle the heroine,
Jinno Hazumi defeated the Remnant leader,
Kijima Touta, and with the help of her allies,
Chiryuu and
Tenku, Kijima was stripped of his memories and reverted to a normal human life. Upon sealing the gate, the inhabitants of the Dark World were stranded on Earth and changed to live as normal humans.
However, 30,000 years later, the time for the gate to open has again come, and as that time approaches, the remaining Remnants slowly regain their memories and revert back to their true forms for
this carnival that comes every 30,000 years... Now, the epic battle has come upon the Earth once again. Past mistakes will be replayed and the vicious circle of love and hate will be re-enacted once more.
