Aincrad Hallowing (アインクラッド・ハロウィン, Ainkuraddo Harō~in?) is the 1st book in the Sword Art Online Alternative: Spell Blade Online spinoff Light Novel series. It is the first volume in the Aincrad Arc.


The 『Sword Art Online』incident.

The great professor, Akihiko Kayaba, has created a breakthrough in the world of VR with his new invention of the NerveGear. However, his plan was truly a dark one. Using his power as the game moderator, he proceeded to lock the 10,000 players who had logged into the SAO servers within the game, charging them with the impossible task of clearing all 100 floors of the castle of Aincrad.

Enter Kazuto Kirigaya.

He was just a normal boy but proved to be an extraordinary man in the world of virtual reality. His leadership and raw skill as a player granted the players of SAO the courage to continue playing the death game, even after two years of being trapped inside. Yet, his devil's luck would not last. After discovering the identity of the Knights of the Blood Oath commander, [[w:c:swordartonline:Heathcliff|]], uncovering him to be Akihiko Kayaba himself, Kazuto would challenge the professor to a duel. However, in so doing, he failed to defeat the professor, losing his life in the process. Without the leader that was Kazuto Kirigaya, the spirit of the SAO players was broken.

It was she that arose to take the torch that Kazuto had dropped. With that torch, she guided the players through the remaining floors using her skill, her voice, and her kindness, as flags to rally at. This is the story of that female player that singlehandedly led to the clearing of the game, releasing the minds of those who were trapped.
