To save Lucy, Natsu engages in a duel with Gajeel, whose dragon slayer magic allows the two to fight on even grounds until Gajeel gains the upper hand by eating iron to regain his energy, leaving Natsu weak without any fire to eat. Meanwhile, Jose's Shadows finally destroy the Fairy Tail guildhall. Lucy helps Natsu by summoning Sagittarius, the only celestial spirit currently in her possession, who is able to start a fire by shooting an arrow at a set of machinery, allowing Natsu to feed and continue fighting.
