Selphie
Suddenly, the Elf made a mistake in his calculation, he used shadow as a medium of transportation, but somehow, are utabdi all of Shadow's tricks, Leo was able to predict he shadow he would appear in.
He saw the shadow move and knew that he had very little time...
So, he immediately teleported right next to the shadow, by the time he appeared, Shadiwof Death was already taking his elven form from the Shadow.
Without further ado, he plunged his dagger forcefully into the dark elf's head.
The dark elf expired with a final gasp, ceasing the need to hold Lucy captive. The shadow tentacles holding Lucy disintegrated into nothingness. Leo emerged from the conflict victorious, his mastery of the Divine Thief Dagger Sutra dagger technique and his combat skills honed from multiple battles with both humans and mutant beast was enough to defeat the dark elf.
