Setsuna is a powerful
spirit of the underworld, let loose through Hell's Gate after Kagami
was defeated. He took physical form on earth by entering the body of an
infant that was killed amidst the confusion of battle. Now, his body is
fully grown, and he appears a beautiful and youthful man; yet this masks
the blackness of his soul. He is full of rage, a loathing for every living
creature, both the spirits of his world and the humans that walk upon ours.
And so he walks amongst them, seething with hatred against all life.
He finds Hibiki
Takane's father, a master blacksmith, and orders him to make him a
powerful, unbreakable sword. For eighty days, Hibiki's father wouldn't eat or
sleep in order to create the blade. When he finishes it, he passes away.
Setsuna continues his massacre while beginning his search for the Sealing
Maiden. He plans to kill her to keep Hell's Gate open and to insure he would
never have return to the Makai.
