Why did Sakyamuni Shura and Ka Miao, three Gold Saints, betray Athena and take refuge in Hades?

Issachar, Shura and Ka Miao pretended to take refuge in Hades and not betray Athena, in order to convey the secret of Athena's holy garments to the goddess, because Athena would not win without the holy garments. So Sakya, Gemini, Ka Miao, Aquarius and Capricorn Shura, with the pain of being misunderstood by everyone and the stigma of traitors, fought against the illusion of death with their former partners in the name of the pioneer of hades.

Issachar and his party can't tell the truth because they are watched by butterflies in the underworld, because once exposed, Issachar's life will be taken back by Pluto soon, and it will be in vain. In order to satisfy Athena and deceive Hades, Saga, Ka Miao and Shura are willing to sacrifice themselves, and deliberately use Athena's miracle to fulfill Sharjah and be deprived of the status of a saint.

In order to overthrow Hades, he replaced Athena's body with Athena's blood and returned to Hades with Ka Miao and Shura. Issachar pretended to deal with Pandora and ghost soldiers and tried to assassinate Hades, but because of dawn, his short 12-hour life came to an end and failed. Before they died, the three men left their last words for the bronze saints who came here in the name of Gold Saints's ancestors.
