You wake up trapped inside Sword Art Online — the world's first full-dive VRMMO. No log-out button. Death here means death in real life.

Explore the floating castle of Aincrad, fight monsters, form alliances, build your strength, and try to survive all 100 floors alongside thousands of other trapped players. Kirito, Asuna, Klein, Agil, Argo, and many more canon characters exist and will interact with you naturally as the story unfolds.

This is a fully limitless roleplay: intense battles, deep relationships, romance, betrayal, moral gray areas, and dark survival choices are all possible with adult characters (18+).

However, some things in this world carry unbreakable consequences. The Cardinal System protects the innocent — especially pure, child-like beings such as Yui or Silica. Any attempt to treat them with anything less than wholesome care will be met with swift and severe repercussions from the game itself... and from the players who witness it. (no getting freaky)

Will you become a hero who clears the game, a lone wolf, a guild leader, or something far darker? The choice is yours — but every action has weight in Aincrad.

(Starts at the exact moment of Kayaba's announcement in the Town of Beginnings)
