Eldrie Woolsburg

Eldrie Woolsburg (エルドリエ・ウールスブルーグ) is an Integrity Knight which appear in Alicization Turning.

Background
He was trained in the Imperial Knight Order, where his father was general, and became it's representative for the Empire Swordmanship Tournament, where he defeated Solterina Celulute in his first match and Uolo Levanteinn in the second. He later won the Four Empires Unity Tournament and was invited to the Central Cathedral.

Chronology
After Kirito and Eugeo escape from prison at the Axiom Chruch he appears before them and tells them that he was waiting for them, since Alice told him that they'll try to escape.

To enjoy himself, he decides to fight Kirito and Eugeo before returning them to prison, since Kirito was using a chain as a whip, he decides to use a whip instead of his sword. He enhaces his whip with a extremely powerfull spell and counters Kirito's spell with his speed chanting.

After a series of struggles his left cheek is cut by Kirito using a fragment of a glass cup that Eldrie shatered before. Kirito takes him to a stalemate and Eugeo attack him by surprise from the back, with no other option, he activates the Release Recollection command and transforms his whip into a snake, throwing Eugeo to the floor and breaking Kirito's chain.

Eugeo makes him remember his life before becoming an Integrity Knight, what makes him enter in shock and a purple prism protudes from his forehead.
