Asuna ALO copy


Sometimes the things that matter the most are right in front of you.
~ Asuna


Asuna Yuuki (結城 明日奈, Yūki Asuna), better known by her username Asuna, is the deuteragonist of Sword Art Online.

Prior to being trapped in the game, Asuna was known to be somewhat stuck-up and proud of her position in a well-to-do family. However, she was terrified by the thought of being unable to leave the game, but eventually found the resolve to take charge of her own fate, recklessly slaying hordes of monsters on her own and leveling up at a rapid pace to the point of gaining infamy within the community.

Nicknamed "The Flash" for her nearly unparalleled speed, she crossed paths with Kirito numerous times, eventually becoming one of his closest allies and later his betrothed.

Standard Equipment:

  • Lambent Light
  • Crest of Yggdrasil
  • Lambent Light: A one-handed rapier forged by Asuna's friend Lisbeth, who said that it is of a quality that she can only forge once every 3 months. This became her primary and endgame weapon in Sword Art Online.
  • Unnamed Rapier: A one-handed rapier that Asuna uses in ALO.
  • Crest of Yggdrasil: A 1.5 meter long two-handed staff. It was given by Kirito after he accidentally broke off a branch from the World Tree in Alfheim Online. She uses this whenever she is relegated to a supportive role, often the party healer. This, in conjunction with her mastery of the rapier made her known in ALO as "Berserk Healer".

Intelligence: Brilliant tactician as she is the Vice Commander of the strongest guild in Aincrad, the Knights of Blood. Masterful rapier user to the point that she became known as "The Flash" for her speedy and dexterous strikes that even Kirito noted that he cannot follow.

Weaknesses: Sword Skills have a slight aftercast delay at the end of them in exchange for increased power.

Notable Attacks/Techniques:

  • Star Splash
  • Flashing Penetrator

Sword Skills

Sword Skills (SS): A series of movements that allows the user to attack much faster than they normally could, but the movements required to perform the Sword Skill are fixed and cannot be canceled by the user after they begin performing it. Contrary to their name, Sword Skills do not have to be used with a sword. Also note that these may not be all of Asuna's Sword Skills, but simply most of the ones she has been shown to use. Cannot be used in Alfheim Online pre-New Aincrad (Can only use imitations).

  • Linear: A single, quick thrust forward. The skill has a remarkably short post-motion delay after usage, allowing multiple Linears to be chained in together at a very short amount of time.
  • Oblique: A low thrust skill. Its range is shorter than Linear's, but the power is higher due to the user's weight behind it.
  • Shooting Star: A charging rapier skill.
  • Flashing Penetrator: A high-powered charging attack that makes a sonic boom and leaves a trail not unlike the tail of a comet. Although the skill only really hits one target, anyone caught in its charge gets blown away. It is typically unused in a 1v1 situation due to requiring the user to sprint to build up speed but is a good attack to disrupt enemy positioning. It has long aftercast delay.
  • Parallel Sting: A 2-hit sword skill.
  • Triangular: A powerful 3-hit skill.
  • Quadruple Pain: A 4-hit combo that Asuna used against Yuuki's Mother's Rosario. Though she lost, it was notable that it brought Yuuki down to yellow health.
  • Neutron: A powerful 5-hit skill.
  • Star Splash: A high-level 8-hit combo that begins with 3 short thrusts to the chest that are notably low-damage but extremely fast, followed by two slashes at the legs, two jabs, high and low, and finally, a strong jab to the chest.

Original Sword Skills

Original Sword Skills (OSS): Sword skills made by or is inherited by the user from another. It is done by recording the creator's movements while the skill is being done. It is very difficult as it requires the user to do it perfectly as speeds above how they normally do, at speeds of that of sword skills. Cannot be used in Sword Art Online (Old Aincrad).

  • Starry Tear: A powerful 5-hit combo skill.
  • Mother's Rosario:
    Mothers rosario asuna

    Asuna's Mother's Rosario

    An 11-hit combo she inherited from Yuuki. The skill begins with five consecutive stabs in a straight line from the top right to the bottom left. The user then draws their sword back and performs another five consecutive stabs in a straight line from the top left to the bottom right, perpendicular to the prior five. The two lines together form an X shape with their third hit overlapping. Finally, the user tilts their body and uses their entire strength to perform a last stab directly at the intersection of the cross-shape created by the former ten strikes.


Magic: Allows the user to use race-unique and Alfheim standard magic. Asuna, as an Undine is naturally inclined towards recovery-based magic and the water element but she also uses standard elemental magic to imbue her rapier with it. Alfheim Online (ALO) Asuna only.

  • Support Magic: Though capable of using other types of magic, the Undines are experts in using high-ranking recovery and support magic due to their high-level magic capabilities.
  • Underwater Combat: Due to their affinity with water, Undines are experts in underwater combat. This makes them valuable assets when faced with water-type monsters.
  • Wall Run: As one of the lightweight races, the Undines are capable of using the skill Wall Run, that, as the name suggests, allows them to temporarily run on walls. The normal limit is a distance of ten meters, but those with an extremely high sprinting speed are known to be able to run for about thirty meters.
