Cross Over! The Acheron River

Shiryu, Hyoga and Shun are about to jump into the hole leading to the Underworld, but Dohko stops them, warning them that only Specters will be able to reach that world alive. He also tells them that they must reach Arayashiki, known as the Eighth Sense. Shaka and Athena had reached this sense by being as close to death as possible, to reach the Underworld alive. Dohko and the Bronze Saints, thanks to their previous battles, awaken the Eighth Sense, and land in the Underworld. Seiya has made it as well, reaching the Eighth Sense beforehand and encounters Shun. Now they must find Saori and give her Cloth to her. Seiya and Shun reach the Acheron River, and see dead people who lived their lives in apathy and aren't allowed to cross the river. A boat comes with a Specter, Acheron Charon, who guides dead people across the river. He begins to fight the Saints, but offers them a ride in exchange for money. Shun offers Charon a golden pendant, something he has had since he was a baby. Even though Charon says it isn't enough, he gives them a ride. At the halfway point, Charon knocks Seiya off the boat where he is being dragged to the bottom by dead people who tried to swim across. Shun saves Seiya and he attacks, breaking through Charon's Rolling Oar defense. The Specter falls into the water, asking for help since only he knows the way to the other side. Shun helps him, but Charon attacks Seiya with Eddying Current Crusher. He then attacks Shun, but looks at his pure eyes, being aware of his pure heart and stops the attack, thinking he might end up in Elysium, a paradise for people chosen by the Gods. Thankful to Shun, Charon returns him his pendant and agrees to take him and Seiya to the other side, on the condition they settle the score. Charon explains the contents of the Underworld, consisting of 8 prisons, 3 valleys, 10 pits, and 4 spheres. Seiya and Charon continue their battle. Since Seiya has seen both of Charon's techniques, he is victorious, killing the Specter with his Meteor of Pegasus. Hyoga, Shiryu, Dohko and Kanon have also made it to the Underworld, but are in different parts of it. Seiya and Shun reach the First Prison, the Palace of Justice.
