Background
Asuna and Kirito find the 74th floor Boss Room after mapping for some time. Curious, they take a peek inside and see The Gleam Eyes staring at them. They immediately run away in fear.

They encounter The Gleam Eyes again when they are forced to fight it in order to save the members of Aincrad Liberation Force. After the death of Colbert at the hands of The Gleam Eyes Asuna, Kirito and Klein leap to the rescue and defeat the boss. Though they sucessfully defeat the boss it suceeds in taking three lives, this is the first time casualties resulted from a boss battle since the 67th floor.

The 74th floor is also the first time a boss room contained an Anti-Crystal Area trap.
