Quick recap
At Hades' castle in Germany, Ikki faces Pandora and Radamanthys, and the Bronze Saints awaken the Eighth Sense to enter the underworld alive. Seiya and Shun cross the Acheron on Charon's boat and pass through the prisons of the underworld, where Specters judge and punish souls. Kanon stays behind to hold off Radamanthys. In Giudecca the truth comes out: Shun is Hades' chosen vessel, and the god takes over his body. Ikki and Seiya manage to free him, and Hades' soul flees to Elysion, where his real body rests. To open the way, all twelve Gold Saints gather at the Wailing Wall and sacrifice themselves together to bring it down.
