The 25th Floor (第25層, Dai 25-sō?) of Aincrad was a Floor that was exceedingly more difficult than the 24th Floor, possessing abnormally strong monsters, complex topography and was thus the site of many deaths in Sword Art Online.

Geography[]

The topography of the Floor is as complex as a maze with plenty of pitfall traps throughout the floor leading to poisonous swamps.

History[]

The Clearers reached the 25th Floor between February[1] and March[2], 2023. Due to this particular Floor being incomparably more dangerous than the previous floor, many players lost their lives by simply navigating towards the next town as a result of the numerous traps and powerful monsters throughout the Floor. By the time the Clearers managed to finally reach the Labyrinth, the group's spirit had nearly reached its breaking point. At the time, Kibaou had been a central figure at maintaining the morale of the frontline players; however, misled by false information just before the boss battle at the top of the Labyrinth, the man and his guild, the Aincrad Liberation Squad (ALS), recklessly charged into the Boss Room with a sub-optimal raid party composed of approximately forty players under his command, eight players short of a full raid party. By the time the main force of the frontline players arrived at the boss room, over half of the members of the guild had met their demise. Although the boss was ultimately defeated, the great death toll among both the ALS, and the other frontline players that arrived as reinforcements midway into the battle, left the Clearers devastated in the aftermath. As a result, Kibaou and his remaining guildmates departed from the frontlines back to the 1st Floor, where they eventually merged with the mutual-aid organization «MMO Today» led by Thinker, forming a congregation which later became known as the "Aincrad Liberation Force". Meanwhile, the Clearers as a whole were reduced to two thirds of their original size due to the casualties experienced on the floor.

Known Bosses[]

  • Two-Headed Giant[3] (Labyrinth Boss)
