Leyshren Zed Yofilis

Leyshren Zed Yofilis (レーシュレン・ゼド・ヨフィリス), commonly referred to as simply Yofilis, is the dark elven ruler of Yofel Castle on the 4th Floor of Aincrad and one of the most elderly individuals of the dark elves. He is one of the Non-Player Characters involved in the Elf War campaign quest.

Appearance
Yofilis had long, black hair tied behind him, slender hands, green-grey eyes, and an old, vertical scar running from his hairline to his chin across his left eye. His cheeks were rather light-skinned for a dark elf.

Yofilis wore fittingly noble clothes: a rococo-styled frock coat covered with moire and buttons, a vest, pants that stopped below the knees, white tights, white gloves, and a white tie packed with frills. He was armed with a fragile rapier at his waist.

According to Kirito, Yofilis had a flat voice that could be taken as young or brittle.

Background
After receiving his scar, the greatly ashamed Yofilis chose to live in seclusion in his dark office to keep his scar hidden from others and to prevent disgracing his children. For this goal, Yofilis created a story about suffering from an illness that made him sensitive to bright light. Due to this lie and his long time of seclusion, most of the residents of the castle had never once seen his face.

On December 24, 2022, Kirito, Asuna, and Kizmel came to Yofilis’s office to report the possibility of the Fallen Elves attacking Yofel Castle to acquire the Jade Key to viscount Yofilis. The viscount questioned why there were humans in the castle, and Kirito presented the scroll of recommendations he had received from the Dark Elven Commander to him. After reading the scroll and discovering Kirito and Asuna’s involvement in recovering the Jade Key, Yofilis rewarded the two with Sigils of Lyusula, and then requested to continue the report. Once the report was completed, due to Asuna’s question, Yofilis told the two players about the two different legends concerning the keys to the Sanctuary, and, under Kizmel’s proposal, requested the humans to aid Kizmel in retrieving the Lapis Key while the castle prepared for the upcoming invasion.

During the invasion of Yofel Castle on December 27, 2022, Yofilis remained in his office until Kirito entered the office to report the dire situation of the battle. Hearing this, Yofilis stated that he would wait for the enemy to come to him, and advised Kirito to leave the castle with his companions. However, when Kirito instead that the morale of the dark elven warriors was low due to the lack of presence of Yofilis, their commander, on the battlefield. After some convincing, Yofilis asked Kirito why he was aiding them, and hearing his honest answer, Yofilis revealed that his illness was actually a lie and decided to join the battle.

Having used a secret passage to descend to the entrance, Yofilis entered the battlefield, and beseeched his warriors to fight alongside him. This caused the morale of the dark elves to skyrocket, and resulted in various buffs being granted to the dark elven side. When six forest elves lined up to use Sword Skills simultaneously, Yofilis used «Flashing Penetrator» to break through them and send them into the air.

After the battle, Yofilis ordered his soldiers to bring an enormous chest, and allowed Kirito to choose two items as rewards. However, before Kirito could make a decision, Asuna returned from checking on updates from Argo, and informed him that the boss raid was about to begin. Hearing this, Yofilis and Kizmel shared their knowledge about the boss, and announced that they would help defeat it. At the boss room, boosted the morale of the raid, once again granting various buffs, and greatly contributed to defeating the boss, using charms to run on the surface of the water when the boss used its special ability.
