Sukinowa is the faithful servant of the god Tsukuyomi. His loyalty is pledged to the fullest. The evil wizard gained the entrance into the kingdom of Yamato through deception, as he gave the king a night of rain to earn the lord's trust. Over the years, Sukinowa bid his time for his master's arrival, watching for the signs that would herald the god's return. The first omen he witnessed was the birth of twin boys from the Queen. The blessed event terrified the warlock to the bone, as he feared that it could be a sign of the twin boys birthed from the father god Izanagi. Sneaking the younger of the two away, he prepared to drop the baby from a cliff, but the Phoenix of Amano intervened and returned the child to the palace. The dark magician watched from afar and awaited for the child to grow into a man before he attacking a second time. However, once again fate was against Sukinowa, as the young man dispelled the toxic gas that threatened to kill him with his sacred stone.

Sukinowa realized that it was beyond his power to kill the child, so instead decided to play on the king's mind. The dark wizard proceeded to make the queen deathly ill, while framing her youngest son. The ploy worked against the king's son, who attempted to avenge his mother by dueling against his own brother, a confrontation which cost the eldest child his life. The dark soothsayer then convinced the lord that it was his youngest son who set this events in motion. Shocked by the evident news, the King banished his own offspring to the land of Kumaso, an evil and vile place where only the most repulsive dwell.

The wizard watched at a distance, when the boy, now gaining the title "Yamato Takeru", and a new ally, Oto, began their return after defeating the warlord in Kumaso. Summoning a fierce storm and the God of the Sea, Kaishin Muba, Sukinowa sought to kill the boy and retrieve the stolen Sword of Amano. However, the plan was a failure, and the son of Yamato escaped. Time was growing short, and the sorcerer needed to get back the sword for his returning master, yet the faithful servant hadn't exhausted his attempts yet. Taking the form of Yamato Takeru's mother, Sukinowa laid on the beach shore waiting for the lie to take effect, and soon enough the child fell for it. Not seeing past the veil of mystery, Sukinowa pulled from his scarab and plunged the dagger through the warrior's throat. However, Yamato Takeru was not dead, and instead pulled free the knife and threw it at the retreating enchanter. Yet Sukinowa still lived, and carried with him the Sword of the Dark Cloud. The elderly man climbed onto Tsukuyomi's alter, and offered the weapon to his master, which now had landed on the moon. The god accepted his weapon, and, as the blade entered the immortal's hand, Sukinowa crumbled to his true form. Turning back into a huge bony tooth of the legendary hydra, the augurer's mission was fulfilled.

Ten million years ago the Earth first bared witness to the fury of a god. Thousands of tons of sculpted bone and muscle, sheathed over in a crimson wash of scales, trampled mountains into dust, forest into ash, and oceans into dry ravines. The eight-headed hydra was imbued with the cosmos themselves. Twin scarlet bolts of lightening, from each pair of cat like eyes leveled nearly all life on Earth. The only reason the devil did not succeed, was because of a warrior of the gods, Susano. The hydra was struck down, and sealed away in an icy prison. Banding together, the gods ended the wrathful spree of the reptilian giant for the time being.

The next time Orochi was seen on the moon, as Tsukuyomi was filled with mirth at his defeat from Yamato Takeru. His heart begged and cried out for the mortal's tattered souls, shouting for their deaths. Oto and Yamato Takeru glazed with wide eyes as the flame-spewing monster showed itself to humanity again. The two humans tired to fight against the wading leviathan, but, even with the help of the Amano Phoenix, they could not prevail. Breathing one last gout of fire, the dragon sent the humans into the dead of space. While there, the man realized the truth of the three Lights of Yamato, and the warrior was turned into the god-like fighter Utsuno Ikusagami. The warrior descended to the moon again, and battled the hydra, knowing that the fate of Earth rested on his shoulders. Blood hued bolts of power surged from each slit eye, showering waves of rolling flames were spout from each fanged maw. However, Orochi could not prevail, and so was defeated by the warrior god Utsuno Ikusagmi. After the colossal battle, the human trapped the god Tsukuyomi's body in his medallion and cast the tainted jewel into space, ending the demon's reign.
