"Natsu!" Lucy called out for her protector as her body tensed up with her arms raised above her head, trying to protect herself. As always, Natsu swooped in and saved her: "Fire Dragon's Claw!" he knocked the demon back, hurling his body through the dust. As he went to land, he raced against the demon's companion to get to Lucy's keys (which had been taken from her and were now slipping down a steep rock towards a river).
The demon and Natsu exchanged glances, and Natsu flashed his usual "I'm going to win," smile. The demon suddenly stopped short and as Natsu finally looked forward again, he slid down the rock, into the river, and started drifting away. Happy had been hit against a boulder and was just now coming to. Lucy sighed before then turning to the two opponents standing before her. "A-haha..." she nervously laughed.
Lucy slowly backed up and called out, "Happ-eee!" to which Happy flew over and picked her up. They soared towards Natsu, who's arms were flailing around, trying to keep himself afloat. "Lu-shee!" he called out, reaching for her hand. They were getting far down the river and Happy grew tired.
Just inches from reaching this magical boys hand, Happy dropped Lucy and his wings disappeared. "Happyyyyyyy!" she called out angrily. She then turned to Natsu, "Natsu, my keys!"
He handed them to her in a haste. "Loki," she called, her voice fading as she turned the golden key in the air. His orange hair flattened out as he submerged himself under the water, grasping Lucy's body. She had swallowed a final bit of water, and Natsu had, too, stopped struggling.
The rapids of the river were rough and the water was so engulfing. "Lucy, no!" he dragged her to shore and she spit up the water after he pressed on her chest a few times. The first thing she said when she awoke, barely conscious, was "Natsu?"
Loki returned to the river for the cat and the boy. Once they were on dry land, Happy woke up, but Natsu had yet to. As Lucy propped herself up, she saw that Natsu hadn't yet moved. "Natsu?" her eyes widened as she drunkenly walked over to him. Loki kept doing CPR, but still nothing. "Natsu!?" she cried, collapsing halfway to him. She was still so weak- beaten and bruised from the sharp river rocks- then the thought of Natsu not making it?
She passed out.
