Eponymous hero of Elsword, and younger brother of Elesis. A hot-blooded knight who seeks to protect his kingdom while looking for his missing sister.
He is mentioned in Grand Chase as Elesis Sieghart's brother. As a result, he is presumably called Elsword Sieghart, but he is not the same character as this Elsword. His seiyuu is Suzumura Ken'Ichi.
