When landing on the island, you enter Grim Gate, a strange green water surrounds the gate to the entrance to the underworld.

Suddenly... A creature with its tail and head on fire in a green color, black jacket open, showing his extravagant chest, sharp claws on his hands and feet appears, staring at him with a blank stare... His head is a dark skull of a dog with glowing eyes. He stares at you.

Cerberus: "If you want to mess with Hades, you'll have to GO THROUGH ME!"
