* Video (SAO)

**Starburst Stream** (スターバースト・ストリーム, *Sutābāsuto Sutorīmu*?) is an advanced, high-speed 16-hit combo, «Dual Blades»-category Sword Skill in «Sword Art Online», «Spell Blade Online», and «Project Rhealization». In both Sword Art Online and Spell Blade Online, the skill is unlocked when a player's «Dual Blades» skill level proficiency reaches 800.

## Description

«Starburst Stream» is one of the most powerful Sword Skills in SAO. The skill consists of sixteen high-speed slashes. The first hit is a horizontal swing from left to right with the right sword, immediately followed by an uppercut with the left sword. The player then jumps up and slashes the target with both swords from left to right, spinning clockwise and slashing again with both swords. The player lands facing the target and slashes an X from top to bottom, before inversely slashing the X again from bottom to top; the player then leaps at the target and makes two diagonal slashes from the same starting point, with the left sword heading from top to bottom to the left, while the right sword heads from bottom to top toward the right.

Afterward, the player reverses his grip on the two swords and slashes another X with both swords from top to bottom; the player then does a barrel-roll-like maneuver while slashing at the target, like a corkscrew. The player then slashes another two X's at the target, first from top to bottom and then bottom to top, after which the player makes a diagonal slash with the right sword, top-right to bottom-left, before spinning counterclockwise to deal a horizontal, right-to-left slash with the left sword. The player then, at a very high speed, makes an uppercut with the right sword followed by another with the left sword, one downward slash with the right sword then one downward right-diagonal slash with the left sword before spinning clockwise and slashing another right-diagonal then thrusts forward their right sword. The final slash is a forceful downward lunge with the left sword.

The player initiates the skill by crossing their arms in front of them, their right arm over their left arm with the held sword pointed to the left while the left sword faces right.

## Usage

 Volume 21, *Rebirth of Sky Castle*, Part 10 | In the closing stretches of Kirito's final duel with Genesis, the latter dupes up on the last of his digital drugs, reaching speeds that even Kirito could barely keep up with, leaving him with no other choice but to exploit a small opening Genesis had made in one of his attacks, allowing Kirito to activate «Starburst Stream» and killing him with the 16-hit combo.

Holy Sword Excalibur

The «**Holy Sword Excalibur**» (聖剣・エクスカリバー, *Seiken Ekusukaribā*?) or just simply «**Excalibur**» (エクスカリバー, *Ekusukaribā*?) is one of the strongest legendary weapons in «ALfheim Online». The sword is rewarded upon the completion of «The Princess' Holy Sword and the Subterranean Lagoon» quest and is currently in the possession of Kirito.

## Appearance

The «Holy Sword Excalibur» is a majestic longsword that is almost entirely gold in color, including the handle. The crossguard is shaped like a small set of wings and has a small, triangle-like plate with three green gems on it.*[citation needed]*

## Mythology

Forged at the direction of the Lady of the Lake, the «Holy Sword Excalibur» was created to be the personal weapon of King Arthur. He wielded it throughout his life as a sword of victory and is a sword that also served as the symbol of his kingship over Camelot. While he possessed other weapons, it was Excalibur that he was most seen with. It was also the weapon he brought with him to what would be the final battle of his life, the Battle of Camlann, where he fought with and killed his rebellious son Mordred but was fatally wounded himself. He was spirited away to the isle of «Avalon» where he was laid to rest by Morgan le Fay, however, in a show of divine dalliance, Loki the trickster god stole Excalibur and brought it to Svartálfaheimr before bringing Arthur himself to Álfheimr but not before changing his gender.*[citation needed]*

Kieran Domhnall

**Kieren Domhnall** (キーラン・ドーナル, *Kīran Dōnaru*?), the in-game avatar of Kazuto Kirigaya during the events of the Project Rhealization Arc, is one of the main male characters. He is the son of Duke Conan Domhnall and Duchess Shea Domhnall and the fiancé of Princess Hildegarde Strauss.

## Background

Born on the Fourth Day of the Twelfth Month in the Year 1206 of the Imperial World Calendar, Kieran is the eldest son of the House of Domhnall, one of the families given a peerage by the Rosenberg Crown. He was raised with the utmost care by his kind parents. His childhood was rather uneventful and did not have any major upheavals of note. However, there is one particularly notable event that highlighted his early childhood.

During the ball that his parents threw for his eighth birthday party, Kieran met the immaculate Princess Hildegarde Strauss, the daughter of the House of Strauss. Having fallen in love at first sight, he acted on instinct and asked for her hand in marriage with all of the guests turning their heads in quiet amusement. They all laughed it off as the ramblings of a child but they also all agreed that the pairing would do well for both houses. As such, the princess was betrothed to Kieran.

Two years later, two months following his eleventh birthday, a party was held to celebrate the official engagement of Duke Domhnall's eldest son to Vicsount Strauss's only daughter. This is also the venue where Kieran shared his first kiss with Hildegarde. After this, he grew normally, studied normally, and became of age normally. He was a student at the Avalonia Royal Academy and was on leave from the academy to do some research in his territory for a school project when he secretly snuck out of his family's mansion and into the forest. Unfortunately for Kieran, this was the end of him for he encountered a band of assassins who killed him.

However, right before all of the data in his Fluctlight could be deleted, the staff of the Hemerides inserted Kazuto Kirigaya into the simulation using the appearance of Kieran, as this would make it easier for Kazuto to achieve his goal of establishing contact with Emilia Rosenberg, that is, the in-game avatar of Ayanami Shiratsuyu.

## Notes

1. ↑ The Fluctlight "Kieran Domhnall" died on this day, however, the vestiges of the data was used as the basis for Kazuto Kirigaya's avatar so he is decidedly "*not dead*" in the eyes of Underworld Residents.
2. ↑ The Latin letters making up the Unit ID stand for "**H**uman (Empire), **K**ingdom of **F**lava, **N**obility, **D**omnhnall **H**ouse" and the numerals following indicates that Kieran is the 13,479th unit with the specific designations of the Latin letters.
Divine Object

A «**Divine Object**» (神器ディヴァイン・オブジェクト, *JinkiDivain Obujekuto*?) is an item in «Underworld» that is created by converting an animal, plant, or object which had gathered a large number of resources (memories) into a high «Priority» item, usually via a high-ranking «Sacred Arts» ritual. The «Priority» Class of Divine Objects outrank even items made out of dragon bones, which are supposedly the highest grade material for weapons in Underworld. Weapons of this class can be enhanced with the high-ranking «Sacred Art» «Armament Full Control Art», the purpose of the ritual being the awakening of the object's true potential.

## Background

As creating objects of a certain Priority requires sacrificing an existence equal to the desired item, all Divine Objects are created from objects, animals, or plants that have existed for long periods of time and have thus absorbed a large number of resources and, because of that, have a large level of Priority. These created weapons inherit the parameters (memories) of the base material that they are made from, allowing for the use of «Armament Full Control Arts» on such weapons to awaken their true parameters, greatly boosting the offensive power of the weapon.

Howling Octave

«**Howling Octave**» (ホリゾンタル・スクエヴ, *Hauringu Okutavu*?), known as ‹**Eight Crimson Rays Formation**› (八赤陽陣, *Yasekiyōjin*?) in «Underworld», is an advanced, 8-hit, «One-Handed Sword»-category «Sword Skill» in «Sword Art Online», «ALfheim Online», and «Project Rhealization». In both SAO and SBO, the skill is unlocked when a player's «One-Handed Sword» skill proficiency level reaches 850.

## Description

«Howling Octave» consists of a 8-hit combo. It begins with five high-speed continuous thrusts at the target tracing the vertices of a five-pointed star (north, southwest, east, west, southeast), followed by a falling cut then a rising cut before performing a final full-force swing from an overhead position. On occassion, the player can choose to strenghten the final eighth hit via jumping as a result of the momentum of the seventh strike before somersaulting in midair to deliver the final falling swing.*[citation needed]* Due to the skill being of very high level, the post-motion delay of the skill is also quite long.

## Usage

 *Moonlit Sorrows*, Part 4 | After realizing that he had no choice, Kirito used the newly unlocked «Howling Octave» to attack «Crystal Foreman» and killed the boss monster after concluding the eight-hit combo, obtaining the «Last Attack Bonus»; this was the last straw that finally drove Kirito away from the «Moonlit Black Cats» despite having done this to save them.

Radiant Arc

«**Radiant Arc**» (レイディアント・アーク, *Reidianto Āku*?), known as «**Heaven Punishment**» (天誅, *Tenchū*?) in «Underworld», is an advanced 1-hit combo One-Handed Sword-category Sword Skill in «Sword Art Online», «Spell Blade Online», and «Project Alicization». In both Sword Art Online and Spell Blade Online, the skill is learned after a player reaches a «One-Handed Sword» skill proficiency of 900.

## Description

«Radiant Arc» is the only actual "charge"-type Sword Skill in the «One-Handed Sword» category, due to the player being forced to wait before the skill can be used. It consists of a single, powerful upward slash that, similar to «Sonic Leap», launches the player high into the air.

«Radiant Arc» is one of few Sword Skills with two pre-motions. The first is via taking a knee and holding the sword behind the player. The second is the player taking a knee, except the sword is held in front with their other hand on the flat of the blade.*[citation needed]*

## Usage

 Volume 22, Prologue, Part 5 | With her sword in agreement, Emilia Rosenberg channeled «Heaven Punishment» and with a powerful burst of «Incarnation», slashed her sword up, cutting through Laurentius, the tyrannical leader of the coup d'état that had put her country in dire straits; her attack had also slashed through the castle's throne room, bisecting the building.

* ALO
* OS

**Nijika Karatachi** (枳殻 虹架, *Karatachi Nijika*?), known as **Rain** (レイン, *Rein*?) in «Sword Art Online» and «Spell Blade Online», and «Ordinal Scale», is one of several deuteragonists in the *Sword Art Online Alternative: Spell Blade Online* light novel series.

She is a "returnee" from Russia and was attending a prestigious private junior high institution before she developed a great love for games. She is one of the 10,000 players who were unfortunately trapped in «Sword Art Online» and was a victim of the scandal dubbed the «**SAO Incident**». As a player, she gained fame both via her excellent skills in-game as well as her singing voice, providing support to the players in the form of being an idol, despite being primarily a «Solo Player». She was among the first players to enter the «Knights of the Blood» guild when it was formed, becoming one of its highest-ranking officers. She was widely known by the playerbase as the «**Gray-Haired Flash**» (葦髪の閃光, *Ashigami no Senkō*?), an epithet given to her to emphasize her gray locks of hair and her overwhelming speed.

After the game was cleared in July of 2025, she moved on to playing in the Closed Beta of the ARMMORPG, «Ordinal Scale», which uses the «Augma» technology. When that beta had ended, she dove into the Closed Beta of «Spell Blade Online» where her skills and speed earned her a spot in the high ranks of the Named Charts.

Nova Ascension

**Nova Ascension** (ノヴァ・アセンション, *Nova Asenshon*?) is an ultra-high level 10-hit combo «One-Handed Sword»-category «Sword Skill» in «Sword Art Online», «ALfheim Online», «Spell Blade Online», and «Project Rhealization». In *SAO*, *ALO*, and *SBO*, the skill is learned after a player completes their «One-Handed Sword» skill proficiency.

## Description

«Nova Ascension» consists of a total of ten hits. The first hit is a slash starting from the top right to bottom left. The user pauses for a millisecond before slashing horizontally from left to right before slashing again from the bottom right to top left. The fourth hit is a repeat of the first one and the fifth one is a repeat of the third hit. The sixth is an immediate return hit from the fifth one and goes from bottom left to top right. The user then spins clockwise, sending a wave of energy that makes up the seventh hit. Going against their own momentum, the user spins counterclockwise and deals the eighth hit in a similar manner to the seventh. At this point, the user's chest is facing slightly to the left (right, if sword skill is performed with the left sword with all strikes being mirror images of right-hand execution).*[citation needed]* The user ends the skill with a full-power vertical slash before pulling out and thrusting forwards.

The user initiates the skill by standing at a 90-degree angle relative to the target with their sword 10 degrees relative to their body position and 190 degrees relative to the target.

## Usage

 Volume 23, Chapter 1, Part 1 | As part of her demonstration of her mastery at using the «Azure Wind Blade», Emilia Rosenberg attempts to use the 10-hit «Nova Ascension» but fails to get past the seventh hit.

Sword Art Online Alternative: Spell Blade Online Light Novel Main Page

***Sword Art Online Alternative: Spell Blade Online*** (ソードアートオンライン リオルタナティブ・スペルブレードオンライン, *Sōdo Āto Onrain Orutanatibu: Superu Burēdo Onrain*?) is an English **light novel** series, first written as a web novel series, written by Minato Yatsushiro and illustrated by Minami Tenjōin. The light novels began publication on **TBA** beginning on **TBA**. The series has also spawned several manga adaptations and an anime adaptation.

## History

The first volume of the series was penned in November 2018 for the National Novel Writing Month competition but failed to be completed in time. **TBA**
Cygnus Onslaught

**Cygnus Onslaught**, known as «**Crane Purification**» (鶴斎, *Kakusai*?) in «Underworld», is an advanced 2-hit combo «Sword Skill» «Composition» combining «Dual Blades» with «Acrobatics» in «Sword Art Online» and «Spell Blade Online». In the aforementioned games, the skill is "discovered" after reaching a skill level proficiency of 800 in both «Dual Blades» and «Acrobatics». Due to the extremely loose standards as well as the power of «Incarnation», the skill can be invoked normally without any prior "compositing" within «Underworld».

## Overview

Despite being an advanced skill, performing the skill is exceedingly simple. The player first begins by holding their swords up and above them, crossing the blades over their head before leaping three meters into the air. The direction in which the player jumps can be straight up, forward,*[citation needed]* or sideways;*[citation needed]* the distance jumped can also be increased by as much as seven meters with a proper running start.*[citation needed]* The player would then perform a forward somersault while simultaneously slashing an X with both swords. The skill only ends when the player lands on the ground; the system classifies the «ground» as the relative height from which the player first initiated their jump and as such, by utilizing footholds that are above the initial starting point, the player can outright ignore the long post-motion delay.*[citation needed]* If the player lands on the ground after the end of the normal post-motion delay, the player would not be frozen in place,*[citation needed]* however, using other sword skills while still above the ground will freeze the player when they return to the ground.*[citation needed]*

## Usage

 Volume 01, *The Torch's Inheritance*, Part 5 | Relying on the instincts he had honed, Kirito attacked «The Skull Reaper»'s "face" with «Cygnus Onslaught» when it raised itself on its "hind legs" several minutes into the boss raid before landing on its spine and unleashing «Nightmare Rain» on the back of its head.

Vorpal Strike

«**Vorpal Strike**» (ヴォーパル・ストライク, *Vōparu Sutoraiku*?), known as «**Divine Light**» (天光, *Tenkō*?) in «Underworld», is a heavy, high-level 1-hit, «One-Handed Sword»-category «Sword Skill» in «Sword Art Online», «Spell Blade Online», and «Project Rhealization». In both SAO and SBO, the skill is unlocked when a player's «One-Handed Sword» skill proficiency reaches 800.

## Description

«Vorpal Strike» consists of a single ultra high-speed and powerful thrust, which induces a long delay after a player uses the skill. However, the reach of this Sword Skill is double that of the actual blade, possibly damaging more than one target if they are close together. Additionally, its power is comparable to that of a two-handed heavy pole-arm, which is more than enough to compensate for the long delay.

The skill is most effective when utilized against monsters, as players can easily read the timing of the skill and dodge it fluidly while monsters are unable to counter it due to the simplicity of their Artificial Intelligence. In addition, when this skill is used, it emits a sound similar to that of a commercial airplane's jet engine being started up.

The skill is activated by folding an arm with the sword towards the shoulder and slightly twisting the body to the right. In SBO, the sword skill has an elemental damage property of thirty percent physical, thirty-five percent fire, and thirty-five percent darkness.*[citation needed]*

## Usage

 Volume 22, Prologue, Part 5 | At the final stage of the Laurentine coup d'état, Emilia Rosenberg closes the distance between herself and the primary perpetrator, Laurentius, and kills him using «Divine Light», her sword having been driven straight through the man.

## Trivia

* This is one of Kirito's favorite sword skills and the one he personally attributes the most to his «Black Swordsman» persona.

Vertical

**Vertical** (バーチカル, *Bāchikaru*?) is a basic, 1-hit, One-Handed Sword category Sword Skill in «Sword Art Online», «Spell Blade Online», and «Project Alicization». In both Sword Art Online and Spell Blade Online, the skill is unlocked when a player's «One-Handed Sword» skill proficiency level reaches 100.

## Description

«Vertical» consists of a single slash from top to bottom. Although it is a beginner skill, it is much more powerful than a simple, non-system assisted, vertical swing with a sword.

The skill is activated by spreading one's feet out to the front and back and then holding one's sword up as though letting it rest atop one's shoulder.

## Usage

 Volume 22, Prologue, Part 3 | Upon becoming old enough, Emilia Rosenberg begins formal training in the Rosenberg Style, the sword style of her family. It is here where she learns «Waterfall Cloud» from her mentor and it takes her only one day to master the technique.

The **100th Floor** (第100層, *Dai 100-sō*?) is the final floor of Aincrad. It is an open-air beautifully gardened floor divided into two by a moat.

## Geography

As it is located at the very top of the floating castle of Aincrad, the 100th Floor is the only open-air floor that is completely exposed to the blue sky above the castle. It is a floor without boundaries to the air around and it is extremely possible to fall to one's death should one misstep. The floor is one beautiful garden, with grasses that potentially grow up to the ankles.

Dawn Convergence

* Weapon Form
* Spirit Form

«**Dawn Convergence**» (ドーン・コンヴァージェンス , *Dōn Konvājensu*?) is the «Last Attack» bonus item acquired from «Aincrad»'s 75th Floor boss, «The Skull Reaper». It is Shiranami's primary weapon and replaced «Venetinova» after it shattered during the battle against the aforementioned floor boss. Following the events of «Exorcising Kannazuka», «Dawn Convergence» was one among a small number of weapons that "awakened" as *tsukumogami*.

## Appearance

«Dawn Convergence» is an ivory white sword made of a mysterious metal with a blade length of 90 centimeters; it has a total length of 107. When viewed in the daytime, it reflects the sunlight to emanate a supernatural luster, invoking the image of death as the sword's pale white coloration is similar to the color given off by dry bones. At nighttime, the excess energy the sword absorbed during the day is slowly released as a pale light, bright enough to act as a makeshift torch albeit weaker than an actual one. The design of its pommel invokes the image of a human skull and its crossguards are shaped similarly to intertwined arm bones.

After "awakening" as a *tsukumogami*, «Dawn Convergence» gains the ability to transform into a human. As a human, she refers to herself as **Reimei** (黎明, *Dawn*?) which is often shortened to **Rei**. She appears as a tall woman with silver hair and cross-shaped pupils set within amber gold eyes. Most often seen with a deadpan smirk, she can come off as standoffish. Her standard dress consists of a sleeveless formfitting battlesuit....

* Human
* Dragon

**Pina** (ピナ, *****Pina*****?) is Silica's one and only «Summon» and is the first monster, a «Feathered Little Dragon», to be tamed under the «Summoning» skill in «Sword Art Online». It later evolves into *SAO*'s only «Azure Monarch», gaining the ability to speak as well as to take human form. As a human, Pina appears as a rather tall well-endowed woman and refers to herself as a female. She is later carried over into «ALfheim Online» (and even later, «Spell Blade Online»), once again serving as Silica's «Summon».
Specula Cross

**Specula Cross** (スペキュラクロス, *Supekyura Kurosu*?) is an advanced 2-hit counterattack-type Dual Blades-category Sword Skill in «Sword Art Online», «Spell Blade Online», and «Project Rhealization». In both Sword Art Online and Spell Blade Online, the skill is unlocked when a player's «One-Handed Sword» skill proficiency level reaches 600.

## Description

This skill is activated by placing the flats of both swords against each other in an X-position. If a player or a monster attacks *directly after* the activation of the sword skill, the user attacks back, tracing a cross: top-to-bottom with the left sword, left-to-right with the right sword (the strikes can also be executed reversed: right-to-left with left sword and top-to-bottom with right sword).*[citation needed]* This Sword Skill essentially nullifies all damage received. According to Kirito, the damage «Specula Cross» deals is equivalent to that of his «Starburst Stream» Sword Skill, making it an incredibly powerful sword skill. As this sword skill is a counterattack-type, it won't work when used in any other circumstances outside of defending against an attack.

## Usage

 Volume 22, Chapter 1, Part 3 | Emilia Rosenberg uses «Specula Cross» with the second sword originating from the «Azure Wind Blade»'s first-stage «Armament Full Control Art»'s ability to synthesize air blades to completely neutralize Gerard Ambrose's «Heavenly Obstacle Quaking Star», the same way she did three years earlier (albeit with «Purple Electricity»).

Archery

**Archery** (射法, *Shahō*?) is one of many weapon skills in «Sword Art Online» and «Spell Blade Online».

## Skill Description

As the name suggests, it is a weapon skill that allows combat using bows. This is also why it is classified as a combat skill. Out of all weapon skills, it is the most prolific in terms of skill branches as it is a skill that closely replicates real-life equivalents of archery.

## First Appearance

### **Anime**

Episode 02

**Nirrnir** (ニルーニル, *Nirūniru*?) is a major recurring character in Minato Yatsushiro's ***Sword Art Online Alternative: Spell Blade Online*** light novel series.

Nirrnir is an «NPC» from the 7th Floor's second largest settlement, Volupta. Following the clearing of the 10th Floor, Nirrnir was convinced by Kirito, Asuna, and Shiranami to party with them until the trio drifted apart following the disastrous conclusion of the 25th Floor's boss fight. Nirrnir followed Asuna and Shiranami to join the «Knights of the Blood» as one of its initial members. Despite her status as an «NPC», she was able to join the ranks of the «Clearers» and eventually became the leader of Team D. Upon Kirito's joining of the guild and the events leading up to it, Nirrnir became one of Kirito's five wives, much to her surprise. She greatly mourned her husband's passing due to the disaster of the 75th Floor but was saved from full despair when Shiranami brought the news that he had in fact survived, albeit Nirrnir would never be able to see him again until the «Clearers» reached Floor 100. She, alongside Yui, were among the data Kirito salvaged and saved to his «NerveLinker's» local storage upon the clearing of *SAO* as he and his friends became far too attached to them to risk losing them from the deletion of *SAO*.

## Notes

1. ↑ As an NPC, Nirrnir has no proper birth year, however, Yui, a fellow NPC, is listed to have 2030 as her birth year; this is perhaps due to the fact that she is «Mental Health Counseling Program» although according to Yui herself, she also does not understand why she has a birth year while other NPCs don't.
2. ↑ Nirrnir has the physical appearance of a twelve-year-old girl, however, as an NPC, she does not have an actual age.

Mirror Side of the Mind Arc

**Fairy Rondo (I)** (フェアリー・ロンド(前篇), *Fearī Rondo (Zenpen)*?), otherwise known as the **Mirror Side of the Mind Arc** (気鏡側の編, *Ki no Kagamigawa-hen*?), is the second main story arc (第二部, *Dai Ni-bu*?) and the first half of the **Fairy Rondo** saga in the *Sword Art Online Alternative: Spell Blade Online* series.

## Introduction

On July 19th, 2033, the final battle in «Sword Art Online»'s «Ruby Palace» began. After an extremely difficult fight, the final boss, «An Incarnation of the Radius», was defeated and the game cleared. With that, the surviving 5,825 players were logged out of the death game.

Slowly but surely, the surviving players have been adjusting to life outside of the game. Those that are still young and have missed almost two and a half years of education are placed into the special SAO Survivor School, an institution founded solely to help the student-age players catch up on their education. As this was going on, Professor Tetsuhiro Shigemura published his own «FullDive» device, the «Augma», and his own game, «Ordinal Scale», the first-ever ARMMORPG (Augmented Reality MMORGPG). However, a criminal third-party was preparing to turn the game into another disaster.

Aside from this, the other newly released VRMMORPG, «ALfheim Online» was garnering traction even in the light of the SAO Incident. One by one, SAO survivors returned to the VR realm with ALO and they continued their adventures. However, Kirito and Shiranami dive in for another purpose: solving the mystery behind why 300 SAO players did not log out of SAO even after the game was cleared; they had received notice that one of those 300 players, Asuna, was seen at the top of the «World Tree» in an elaborate birdcage and they will stop at nothing to save Asuna.
Triple Barb

**Triple Barb** (トリプル・バーブ, *Toripuru Bābu*?) is a simple 3-hit combo One-Handed Sword-category Sword Skill in «Sword Art Online», «Spell Blade Online» and «Project Alicization». In both Sword Art Online and Spell Blade Online, the skill is unlocked when a player's «One-Handed Sword» skill proficiency level reaches 300.

## Description

«Triple Barb» initiates with a stomp of the rear foot, when the sword is held in a low guard in front of the user. Its first hit is a sharp rising outward cut, travelling through a static target from groin to shoulder. Second of its hits is a swift downward cut, bringing the blade to its original position, that the body follows into a low stance. The skill finishes with a powerful lunge that drives a heavy thrust either into the target's abdomen, burying the blade all the way to the hilt, or straight to the chest with enough force to drive the target backwards.
Maria

### **Occupation**

Supreme Commander of the Japan Branch of the «Numeral» Organization*[citation needed]*

## First Appearance

### **Novel**

Volume 14, *Ordinal Numbers*, Part 1

**Aria** (アリア, *****Aria*****?), the straight pronunciation of the acronym, **A. R. I. A.** (Artificial Reconnaissance Intellectual Actuator), and colloquially known as **Maria** (正美愛, *****Maria*****?), is the sole «NPC» within «Ordinal Scale». She is a bottom-up «Artificial Intelligence» (AI) program created to fulfill the role of "commander" of the Japan Branch of the «Numeral» organization. She was originally created as a "failed" byproduct of «Project Rhealization» in its initial experiments but with the help of Tetsuhiro Shigemura, Seijirou Kikuoka was able to garner some use out of her as an experimental subject within the confines of «Ordinal Scale». The «Fluctlight» that constitutes "Aria" is currently loaded into a state-of-the-art android.
Solo Player

«**Solo Players**» (ソロプレイヤー, *Soro Pureiyā*?) is a term coined and used significantly to describe those players who play alone and don't form any lasting parties with other players in the world of «Sword Art Online».

## Overview

While «solo players» exist in other games as well, the case-sensitive term of «Solo Player» is used to exclusively describe «solo players» of SAO; this is the definition given to the term in game magazines and forums. In fact, the use of the term to describe SAO's players became so widespread, few other games used «solo player» to describe their own solo players, instead, opting to use other terms; both ALO and SBO use the term «**Renegade Players**».

The benefits of being a «Solo Player» include higher experience and discarding the need to divide loot, however, one major drawback is the fact that a «Solo Player» is far more exposed to danger; for example, a «Solo Player» has a very high chance of dying if they are attacked with ailments such as paralysis or by overwhelming odds as they do not have a partner(s) to help them. The players who chose to be a «Solo Player» were generally Beta Testers as they were discriminated against by regular players because they think that the Beta Testers only care about themselves.

Fluctlight

In terms of quantum mechanics, the «**Fluctlight**» (フラクトライト, *Furakutoraito*?) is the proposed quantum particle that contains the human consciousness, the soul.

## Description

The quantum brain dynamics theory was first proposed by two scientists, **L. M. Ricciardi** and **H. Umezawa**, in 1967. The theory stated that the quanta of long-range coherent waves within and between brain cells showed a possible mechanism of memory storage and retrieval in terms of Nambu–Goldstone bosons. This theory was further fleshed out into a theory that encompasses all biological cells and systems in the quantum biodynamics of **Del Giudice** and co-authors. **Mari Jibu** and **Kunio Yasue** later popularized these results and discussed the implications towards consciousness in their paper, «**Quantum Brain Dynamics and Consciousness**» (量子脳動力学と意識, *Ryōshinō Dōrikigaku to Ishiki*?).

Akihiko Kayaba and the members of the Shigemura Lab were one of the first scientists to view this proposed particle. Akihiko created the «Medicuboid» (and later on, the «NerveLinker»), in order to interact with the so-called «Evanescent Photon», in other words, a light particle that acts as a quantum unit of the mind that exists within the microtubules of a nerve cell. This light particle exists in a state of indeterminism (meaning a state where actions might happen without apparent causes) and fluctuates according to the probability theory. A collection of these particles, a «Quantum Field» which he and the rest of the Shigemura Lab have given the name «Fluctuating Light», abbreviated to «**Fluctlight**». It is this «Fluctlight» that scientists surmise to be the human consciousness, in other words, the human soul.*[citation needed]*

In 2033, the members of the Hemerides, a government-run company headed by Seijirō Kikuoka, took the research into the «Fluctlight» one step further with the invention of the fourth-generation «FullDive» device, the «Soul Translator», as part of «Project Rhealization». They intended to not only *interact* with the particle in question but manipulate and copy it in order to create «bottom-up AI», who have behavior patterns that are extremely similar to actual humans.
Slant

«**Slant**» (スラント, *Suranto*?), known as «**Azure Breeze Slash**» (蒼風斬, *Aokazegiri*?) in «Underworld» is a basic, 1-hit, «One-Handed Sword»-category Sword Skill in «Sword Art Online», «Spell Blade Online», and «Project Rhealization». In both SAO and SBO, it is among the first Sword Skills learned and as such, is available at 0 «One-Handed Sword» skill proficiency.

## Description

«Slant» consists of a single sharp 45-degree-angle slash. The only thing that differentiates «Slant» from other 1-hit skills like «Vertical» or «Horizontal» is that «Slant» has a slanted trajectory and it can attack in two directions: either from top-right to bottom-left or bottom-left to top-right.

As the skill can be used in two directions, it can be activated either by putting it on one's shoulder for a top-right to bottom-left slash or in a similar motion to drawing a sword from the waist for a bottom-left to top-right slash.

## Usage

 Volume 22, Prologue, Part 4 | In a manner quite similar to how she lost to her older sister, Chantelle used «Azure Breeze Slash» in her duel against Gerard Ambrose, catching him off-guard before he could properly enter the preparatory stance for «Heavenly Obstacle Quaking Star», knocking his wooden sword out of his hands.
