Elsword

Elsword is an ambitious but hot-headed young swordsman trained by his sister Elesis, the leader of the Red Mercenary Knights. Elesis left her little brother to lead a mission, never to return. Elsword now searches the land for two things: El, the precious gems that power his kingdom, and his missing sister.

Elsword is a master swordsman who excels at close range combat. He's quick on his feet and can hack and slash with the best of them. Not only can he dish it out, but he can take a lot of punishment as well. His only real weakness is magic, but in his mind, there's nothing a sharp piece of steel can't beat.
