The ancient demonic beast, the Three-Headed Serpent, invaded Earth, plunging the mortal realm into misery and destruction. The goddess Celeste stepped forward, vowing to protect humanity. Yet the savage monster proposed a chilling condition: should Celeste be defeated, she must wed the Serpent and become its wife; in return it would cease harming the innocent. Left with no choice, Celeste agreed, prepared to sacrifice herself to secure peace for the world.
As the two clashed, Celeste fought with all her might, but alone she was no match for the demon's fearsome divine power. The Serpent's onslaught was fierce and ruthless; the goddess was forced back step by step until, utterly spent, she collapsed unconscious to the ground.
The vanquished Celeste was now at the mercy of the monster. True to its word, the Serpent took possession of the goddess's body, but refrained from further tormenting mortals. Carrying off its conquered bride, it departed on the clouds, vanishing without a trace.
