Gemini Defteros, also known as the "Demon of Kanon Island" and referred to by Asmita's ghost as "a man who can destroy the stars of a galaxy," initially presents himself as a man of extraordinary savagery, though at his core, he is a serene warrior. He adheres to the philosophy of survival of the strongest. He is the twin brother of the late Gemini Aspros. Defteros' name, alternatively spelled as Jemini no Defuterosu, meaning "Second one," indicates his status as the younger of the twins. During his youth, Defteros faced rejection from Sanctuary as a Saint apprentice. Forced to wear an iron mask to conceal his existence from the outside world, Defteros was protected by his older brother Aspros, who was seen as the rightful future heir of the Gemini Gold Cloth.
On Kanon Island, Defteros assists Tenma in briefly reaching the 7th Sense and understanding how to combine the mastery of Cosmo to become one with nature. After training the young Saint, Defteros departs, telling the unconscious Tenma to take good care of the Pegasus Cloth, possibly out of respect for Asmita, whose blood restored it.
Later, he is seen healing Libra Dohko's wound caused by Hades' sword using Athena's blood. He then asks Dohko to carry a flask of the same blood to Athena's statue in Sanctuary and reveals to him his true identity as the Gemini Gold Saint. He tells Dohko that his life was saved by Bennu Kagaho, who brought him to Kanon Island.
He joins the war against Hades in Sanctuary, surprising Bennu Kagaho by saving Dohko's life through opening an alternate dimension with his Another Dimension attack. He instructs Kagaho to convey a message to Hades, stating they are arriving at the Lost Canvas and that his defeat is near. He later removes the secret of Athena's Cloth from Dohko's memory and sends him with it to the Lost Canvas.
Remaining within the vacuum of the Another Dimension, Defteros is challenged by his brother Aspros, who was revived by Hades in exchange for his loyalty and the secret of Athena's Cloth. They resume their encounter in the 4th Demon Temple: Mars, which now resembles the Temple of the Twins in Sanctuary. Both warriors engage each other in battle while reminiscing about their past.
It was revealed that Defteros was manipulated to assassinate the Pope by his older brother, Aspros, using the Demon Emperor Fist, a technique granting the user complete control over the target until the victim witnesses a death. Defteros managed to fight off the effects of the technique with help from Virgo Asmita long enough to deliver a fatal blow to his brother, completely freeing himself. After his defeat, Aspros applies the Delusional Fist on himself before dying. Defteros took Aspros' body and the Gemini Gold Cloth to Kanon Island.
Returning to the battle at the Mars Temple, Defteros is put under the control of Aspros again. To counter the attack, Defteros demonstrates a new technique, the Mavros Eruption Clast, summoning magma from the depths of the earth to create a violent explosion. Defteros reveals to Aspros that he surpassed his own limits during his training at Kanon Island and uses his technique to free himself again from his brother's control. Despite this, Aspros counters the technique easily with his Galaxian Explosion, overpowering the Gemini Saint into submission. Setting aside fond memories and respect for the once-gentle brother he knew, Defteros engages Aspros in a final effort, pitting his own Galaxian Explosion against his brother's, where only one will emerge as the survivor and victor. Seizing the moment of the clash of the Explosions, Defteros hits his brother with a technique that sacrifices his own life, nullifying the effects of the Delusional Fist on Aspros, making him return to his senses. Afterward, Defteros' body vaporizes, leaving behind the Gemini Gold Cloth. Having sacrificed his life to restore his brother's sanity, Defteros remained content in merging his soul with his brother's.
