|The Gleam Eyes|
|Epithet||The Blue-Eyed Demon|
|Novel||Volume 1 Chapter 9|
|Manga||Aincrad Manga Stage.001|
The Gleam Eyes (ザ・グリーム・アイズ, Za Gurīmu Aizu?) was the boss of Sword Art Online Floor 74. It was the first demon-type boss shown in the story and the only known boss that was defeated without a strategy meeting, with the Black Swordsman Kirito defeating him using «Dual Blades». This was the first time Kirito had ever used the skill in front of his friends and other players.
The Gleam Eyes is a massive, demonic-looking monster, with dark blue skin, a tail resembling a cobra, as well has having horns like on a mountain goat. Its main weapon is an equally massive Zanbato sword, and despite its epithet and the title of the ninth episode, The Gleam Eyes does not have blue eyes, but rather they are red. However, they turn a piercing glowing blue color when Asuna and Kirito first encounter it and remains to have that color for the rest of the fight.
Asuna and Kirito stumbled on the 74th Floor Boss Room after mapping for some time. Curious, they took a peek inside and saw The Gleam Eyes staring at them. They immediately ran away in fear as the boss attempted to attack the two-person party.
They encountered The Gleam Eyes again when they are forced to fight it in order to save the surviving members of The Army raiding party under Corbatz, who were forced to fight it. After the death of Corbatz at the hands of The Gleam Eyes, Asuna and, later, Kirito and Klein lept to the rescue and defeat the boss. Though they successfully defeat the boss, it had succeeded in taking three lives in the process, making this the first time casualties resulted from a boss battle ever since the 67th Floor's boss fight.
The 74th Floor is also the first time a boss room contained an Anti-Crystal Area trap.
The Gleam Eyes was truly worthy of being the boss of the 74th Floor as it could overpower the Aincrad Liberation Force party, (although Corbatz's men were already thoroughly exhausted from exploring the area) succeeded in killing Corbatz and two of his men, and even put the likes of Kirito, Klein and Asuna on the defensive. Able to match the above mentioned players in sword combat, punch Asuna several feet away, as well as send Klein flying despite the latter blocking the attack, Gleam Eyes is a fearsome opponent. Its greatest achievement, however, is that despite being slain by him in the end, Gleam Eyes was able to, even while facing Kirito's unique Dual Wielding skill, reduce the latter's HP down to a mere sliver.
- While in ALfheim Online, Kirito used a spell to transform into a creature similar to the Gleam Eyes to defeat a large Salamander party. Just like the Gleam Eyes, Kirito attacks in a vicious manner while transformed.
- The Gleam Eyes is one of the five in the SAO arc that have managed to inflict heavy or fatal damage on Kirito. The others were Nicholas The Renegade, Kuradeel, The Fatal Scythe, and Heathcliff.
- The Gleam Eyes looks very reminiscent of a satyr from Greek mythology, specifically the god Pan. The only difference is that it, The Gleam Eyes, has a violet cobra for a tail. Satyrs in mythology are normally depicted as being related to fertility and sex.
- The Gleam Eyes is shown in the opening scene in the Aincrad Arc of the anime. The only difference is that The Gleam Eyes is defeated by Kirito and Asuna, instead of Kirito alone. Kirito also attacks the boss with Elucidator only, without using his Dual Blades. When the boss is killed by the two, it explodes, releasing shards and also causes a green-colored explosion, which is impossible in SAO as when a player/monster reaches 0 HP they simply shatter into shards.
