Accel World Wiki

Kazuto Kirigaya (桐ヶ谷和人, Kirigaya Kazuto), in-game name Kirito (キリト), originally a Sword Art Online character, appeared in a short story in Accel World Light Novel Volume 10 chapter 3 and Manga Chapter 18 onward to chapter 20 and had a battle with Silver Crow. In Accel World, he is depicted in his Sword Art Online avatar.

The conclusion of the battle was undecided, as he disconnected the moment before either finishing blow could be dealt.


Kazuto is recruited by Takeru Higa to test out the unnamed 4th generation FullDive equipment. Being an SAO survivor, Higa speculates that he may be able to adapt to the machine better, as the other members of the development team experienced "VR sickness" during the dive. Higa notes that the device will use his "self-image" to generate his avatar. Before diving, Higa warns him about a "ghost" the staffers claimed to have seen, then clarifies that multiple staff members saw a mysterious, indistinct figure when diving.

Kirito dives as his Sword Art Online avatar, equipped with his Blackwrym Coat, as well as Elucidator and Dark Repulser. He finds himself in a barren, dilapidated city not unlike modern Tokyo. He notices Silver Crow and studies him with guarded curiosity. He surmises the setting is a futuristic fighting game and tries to question Silver Crow. However, neither can hear one another. When Silver Crow attempts to make a move to close the distance, Kirito panics and draws his weapon. He concludes that when the duel concludes, he will be ejected from the stage, and decides to give the battle his all.

After a fierce struggle utilizing sword skills and martial arts, Kirito draws Dark Repulser. During the struggle, he notes the simulated pain is on a level illegal in modern-day VR games. When the battle reaches its climax, Kirito and Silver Crow and both disconnected before a deciding blow can be struck, and both are forced to consider it a draw.

Kazuto then tells Higa about the duel, but he doesn't believe him. Any other attempts to re-visit ends in failure, and anyone diving simply lands in the pre-prepared environment. Kazuto speculates that the machine was 'satisfied' after the duel, and has therefore 'fixed' itself.

During the duel, Kirito uses multiplle sword skills from SAO, including Sonic Leap, Meteor Fall, and Double Circular.

  • The 4th generation FullDive equipment may refer to the "Soul Translator (STL)", and thus this takes place before or in the beginning of Alicization arc.
  • The manga reveals that voluntary flight in ALO actually needs at least some minor body movements. Suguha speculates that it's because humans don't actually have wings.
  • Kazuto may have some medical knowledge, or at least about the brain, as he knows which part of it that the AmuSphere (or NerveGear) interface with.
  • Kazuto is able to analyze an opponent or deduce other things (such as his location) in a short amount of time, as he does with Silver Crow during the duel.
