Garuda Aiacos was a Kyoto of Hades in the XX Century.
Aiacos was the guardian of the Ptolomea Sphere in the Meikai, but, never was shown there. He appears at the first time when goes to Giudecca listen the Orphée serenade. But, Orphée uses his lira to do Aiacos sleep, and only after Orphée's death, he was awake.
After this, he goes to the Fifth Prison helps Radamanthys to kill Kanon, but Ikki arrives in the place and after a fight against Aiacos, Ikki defeats him (because Aiacos lost his nervous forces).
