As Lucy looks for a way to release her friends from Pluto's Grim, she is pursued by the members of Tartaros, including the Demon Gates Torafuzar and a resurrected Jackal. Lucy exhausts herself summoning Leo, Virgo, and Aquarius to help fight off the demons. When Jackal corners Lucy, Aquarius advises her to summon the Celestial Spirit King, which requires her to destroy one of her golden Zodiac keys, thus making it impossible to summon that spirit again. Lucy reluctantly sacrifices Aquarius's key at the spirit's urging and summons the king, who cuts down Pluto's Grim and confronts Mard Geer.
