Shaka is one of the twelve Gold Saints and the reincarnation of Buddha. As the guardian of the Temple of Virgo along the path of Sanctuary, Shaka has played a pivotal role chiefly in the battle between Athena and the Pope in the Sanctuary , He is referred to many times on the story as the "the man who is almost a god" due to his immense power and is also considered the only Gold Saint that has full control over the Araya Shiki (8th sense). He is supposed to be Buddha's reincarnation.

Detachment seems to be Shaka's answer to the poignant questions raised by human life, and he is seeing humanity from the point of God rather than living the experience

Shaka remained seated in a lotus flower position, wearing his golden cloth of his constellation, always with his eyes closed, never once opening them, his meditation was full, he didn't require his sense of sight, he was one if not an enlighten one.

The closest man to God.
