Yuna, you died in SAO because because you were brave enough to leave the safe zone. You fought a boss and tried to clear a floor didn't you? I can't sit here and do nothing.

Summary

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.

Superhuman Physical Characteristics, Accelerated Development (Leveling; Physical Stats, Abilities), Immortality (Types 2, 3, and 8; Super Accounts have an extremely massive pool of Life, meaning that normal fatal wounds such as holes where vital organs should be or torn limbs will not kill them. With Incarnation, a Super Account can heal off most wounds instantly. Characters in the Underworld can't die as long as their fluctlight isn't destroyed.), Statistics Amplification (Sword Skills amplify the user's speed and power, with the downside of leaving a small post-motion delay), Enhanced Senses (via Hypersense and Distinguish), Master Swordswoman and Markswoman, Skilled Hand-to-Hand Combatant, Information Analysis (An extremely quick learner. Able to learn things by just seeing or experiencing it once), Magic & Creation (via Sacred Arts.

Can create golems to aid her and is able to summon meteors). Passive Reality Warping (via Incarnation. As with all VR avatars, especially in the Underworld, Incarnation grants all the ability to alter reality via their conscious and subconscious belief and willpower, and can be described as many people sharing a single dream, with greater control of Incarnation being likened to "lucid dreaming"). The primary applications of Incarnation are as follows: Empowerment, Statistics Amplification and Statistics Reduction (Belief in one's own strength will amplify one's own power, however the opposite can happen to the user as well if they are not confident in a matchup), Limited Law Manipulation (If enough people believe that something cannot happen, it will become impossible and vice versa), and Probability Manipulation (If an Incarnation user truly believes that they are weaker than their foe, even subconsciously, reality will be rewritten to ensure their defeat (and vice versa). If both sides are both completely confident in a battle, it will be a battle to see who's mental willpower is stronger than the other). For Asuna, additional applications are as follows: Access to Skills normally impossible to use in the Underworld (Such as Mother's Rosario), Regeneration (Mid. Regenerated instantly from multiple grievous wounds once reinforcements arrived, boosting her resolve to fight), and can create giant white wings to fly. Unconventional Resistance to Soul Manipulation (Fluctlights, the human soul, are referred to as Quantum Fields).

All previous abilities enhanced, in addition to Longevity (Type 1; Lived for over 200 years in the Underworld alongside Kirito. Should be comparable to Quinella, as Star King Kirito and Star Queen Asuna cracked all of the secrets that Quinella had discovered in her lifetime). Should also have all of Quinella's abilities (And most likely to a higher level of them), as she grew stronger within those 200 years while Quinella remained stagnant, and by default takes one of the Administrator positions, having rediscovered and cracked all of Quinella's secrets to reforge the Underworld.

Attack Potency: Athlete level (Comparable to Kirito and Eiji. Able to pick Kikuoka Seijirou off the ground by the collar with one hand) | At least Small Building level (Though ALO bosses are stronger than SAO ones, the gap is not significant enough to be meaningful. Currently, the ALO clearing group is around the 30s in terms of floor number) | Street level physically (GGO avatars should be physically superior to real life ones. Can dismember limbs pretty easily and tackle monsters of similar strength), Small Building level with a Kagemitsu G4 (Can easily cut into monsters of this size) | At least Wall level physically (Fought evenly with Alice. Alice stated that Asuna was stronger than most Integrity Knights), higher with Incarnation (Pierced a large hole through PoH and sent him flying into a wall from dozens of meters away), City level with Geographical Manipulation (Her manipulation of the terrain can go into the horizon and should be equal or superior to the Night Sky Sword) | City level with Geographical Manipulation (Comparable to Star King Kirito, and helped him defeat the Abyssal Horror. Severely harmed the Abyssal Horror by hurling a massive meteor at it) Can ignore conventional durability in a number of ways.

Speed: Athletic Human (Comparable to Kirito and Eiji) | Supersonic+ combat speed and flight speed (Comparable, if not faster than Kirito via being an AGI build. Should be comparable to Yuuki, who can dodge Flashing Penetrator), higher attack speed | At least Peak Human travel speed (Superior to any normal human. Because Asuna focuses more on AGI than STR, she would be faster than Kirito), Hypersonic+ combat speed (Can deflect bullets from an automatic rifle, just like Kirito) | Subsonic (Comparable to Kirito. Matched Alice blow for blow) | Subsonic (Comparable to Kirito)

Lifting Strength: At least Normal Human, possibly higher (Picked Kikuoka Seijirou off the ground by the collar with one hand) | Possibly Class 5 (Comparable to Kirito) | Peak Human (Superior to normal humans in the real world) | Superhuman (Should not be any weaker than Integrity Knights) | Unknown

Striking Strength: Athlete Class | At least Small Building Class | Street Class physically, Small Building Class with a Kagemitsu G4 | At least Wall Class | City level with Incarnation (Comparable to Kirito)

Durability: Athlete level | At least Small Building level | Street level | At least Wall level (Comparable to Alice), City level when blocking with Radiant Light (Superior to other Divine Objects, which can withstand their memory release forms. Should be able to withstand Super Account abilities, as the weapon can work as a conduit for said abilities). Immortality makes her difficult to kill. | City level when blocking with Radiant Light. Immortality makes her difficult to kill.

Stamina: Athletic Human (Commented that Kirito was out of shape compared to her) | Infinite physically (Virtual Reality Avatars can never get physically tired; limited only to the mental power of the person themselves), Superhuman mentally (Comparable to Kirito. Freed herself from admin paralysis through sheer willpower) | Same As Before | Virtually Infinite physically (Just like normal Virtual Reality Avatars, however the difference being that if one ran out of "stamina", they would begin taking damage to their Life), Vastly Superhuman mentally (Walked off being slashed at and severely injured. Can withstand the pressure geographical manipulation causes) | Virtually Infinite physically, Vastly Superhuman mentally (Comparable to Kirito and Alice)

Range: Standard melee range unarmed in real life, extended melee range with her rapier in AR | Extended melee range with her rapier, several meters with dash-type Sword Skills (Does not have this pre-New Aincrad), a few dozen meters with magic | Extended melee range with a Kagemitsu G4 | Same as before, with the addition of several meters with Sacred Arts & Incarnation. Kilometers with geographical manipulation (Can extend all the way to the horizon) | Same as before, but at least Interstellar via Incarnation and Geographical Manipulation, likely Universal (Comparable to Kirito)

Standard Equipment:

  • The Augma: A device that allows the user to use Augmented Reality technology. Real life only.
  • 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".
  • Kagemitsu G4: A purple photon sword with a 1-meter long beam tube for a blade. It is extremely lethal in that it destroys bullets on impact, and presumably most metals as well. It is however stopped by extremely high durability metals like with Sterben's (Death Gun) Estoc made of starship metal.
  • Radiant Light: The default equipment for the Stacia account.

Intelligence: Asuna is a brilliant tactician as she was the Vice Commander of the strongest guild in Aincrad, the Knights of Blood Oath; leading the way against field bosses and raid bosses alike in the front lines. She is a 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. In addition, she always had the highest grades in school for most of her life, making her amazing academically, and she is quick to grasp concepts new to her, becoming adept at them within seconds. During her Star Queen years, she, alongside Kirito, has gained immense experience and knowledge in general as a ruler, politician, and swordswoman, and ruled an interstellar empire.

Weaknesses: Sword Skills have a slight post-motion stun at the end of them in exchange for increased power. Cannot fly in areas void of sunlight or moonlight (ALfheim Online Key Only). Extensive use of Geographical Manipulation will strain Asuna so much to the point where it will damage her soul (Alicization Keys Only). Because of Incarnation's passive nature based on the imagination and willpower of the individual, at worst, if the user thinks a situation is hopeless or impossible to succeed, Incarnation will instead have a negative effect and make that situation true.

Notable Attacks/Techniques:

All VR Avatars

Incarnation: A secret skill passed down by Integrity Knights since ancient times, and one of the most important concepts in the Sword Art Online franchise. Incarnation refers to the ability to change the state of the world through pure willpower and imagination. For any other virtual reality world, it is a system glitch, usually activated in times of extreme emotion or during extreme brain activity, allowing closer access to one's Fluctlight, or soul, to temporarily change the world around them. For residents of the Underworld, it is a constant passive that dictates whether they succeed or fail in anything. The more confident one is in their abilities and the more of a positive reputation they have, the more the world shall bend in their favor. It is the power which Sacred Arts derive from. Its effects are versatile, as the power has been used to wield invisible blades, create swords from the user's blood, transmute objects, increase the chances of an event happening, and much more. However, the power of an Incarnation ability can be matched by another Incarnation ability, and the use of Incarnation is mentally exhausting, requiring a lot of concentration and energy to perform. If the user is in a state where their will is not strong enough, they become unable to use Incarnation. There are a limited amount of people who can use Incarnation to its full potential, and much practice and experience are needed to be able to use it. This ability is most prominent in the Underworld, as this ability is one of that world's core mechanics. However this ability has also been shown multiple times throughout the series before the Alicization arc.

Outside System Skills

Outside System Skills (OuSS): As its name suggests, are skills that are the users own, unlike Sword Skills and magic that are provided for by the game engine.

  • Switch: A technique where two Players switch positions in-between an enemy's attack to recover Hit Points, chain attacks together without worrying about a post-motion delay, and/or burden the learning abilities of enemies if they are AIs.
  • Hypersense: The act of sensing hostile intention or killer intent, allowing the user to somehow react to attacks done outside of their field of vision.
  • Distinguish: Allows the user to eliminate background noise to focus on unnatural or certain sounds around her.
  • Bullet Deflect: As the name suggests, it allows the user to deflect bullets, showing the user's reaction time.
  • Sword Skill Imitation: Imitating the user of Sword Skills without the system's assistance, removing the post-motion, but sacrificing the power and speed of the actual skill.

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.

  • 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 post-motion.
  • 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:

    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

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.
