==Summary==
Note: Spoilers for Sword Art Online: Ordinal Scale.
Eiji Nochizawa (後沢 鋭二, Nochizawa Eiji), known as Nautilus (ノーチラス, Nōchirasu) in Sword Art Online (SAO) and Eiji (エイジ, Eiji) in Ordinal Scale (OS), is one of the antagonists of the Ordinal Scale movie and one of the main characters of the Ordinal Scale side stories, including Hopeful Chant and Cordial Chords. He was the childhood friend of Shigemura Yuuna (Yuna), and was one of the 10,000 players who were trapped in Sword Art Online, where he suffered from a FullDive Non-Conformity condition that impeded his movement whenever he felt that he was in danger. Despite his condition, Eiji as Nautilus managed to be recruited by the Knights of the Blood due to his levelling progress; however, after his condition endangered his party during his first battle against a mid-boss, he was forbidden from taking part in the 40th Floor Boss battle. On the day of the boss battle, he led an emergency rescue party to aid a party of players who became trapped in the boss room itself. This rescue attempt resulted in Yuna sacrificing herself to save the party, leaving Nautilus distraught and depressed, resulting in him leaving his guild to seclude himself in an inn on the 1st Floor for the remainder of the game in the aftermath of the incident.
After Sword Art Online was cleared, Eiji continued his life in seclusion in his apartment, until Yuuna's father, Professor Shigemura Tetsuhiro, recruited him to help with his plan to restore Yuuna as an Artificial Intelligence by reconstructing her personality from memories of her retrieved from Sword Art Online survivors through brains scans conducted with the Augma when their memories of Sword Art Online were stimulated via fighting SAO bosses in Ordinal Scale. To this end, Eiji received a special exosuit from the Professor that enhanced his physical capabilities, allowing him to easily reach rank 2 in Ordinal Scale and assist in retrieving memories from former SAO players. In the final phase of their plan, however, Eiji was betrayed by the Professor, who summoned an SAO boss to attack him and scan his memories of Yuna. After the plan to revive Yuna by endangering the lives of former SAO players was thwarted by Kirigaya Kazuto (Kirito), Eiji surrendered to the police due to having injured the members of Fuurinkazanin (Klein's guild) in real life while gathering memories to revive Yuna.

Because access to the full scope of Incarnation requires the usage of the Soul Translator device, Eiji only has access to Proto-Incarnation)
</tabber>
Attack Potency: Human level (Without the exosuit, Eiji is just a regular human), Street level with the exosuit (Enhances his physical characteristics greatly, to the point where he was before they could react. ) | At least Small Building level (Every 10 floors the difficulty on that specific floor spikes, and every 25 floors it spikes even more. The Floor Boss of the 25th floor nearly wiped out the entirety of the Aincrad Libration Squad, the guild with the highest player count with comparable levels to each other, even with reinforcements. Eiji is on par with floor 40 players and NPCs) | Building level+ (Comparable to other ALfheim Online players such as Kirito) | Building level (Should at least be on-par with Kirito and Eugeo during the Human Realm Arc, as his Avatar is leveled considerably). At least Building level with YUNA (Managed to keep pace with PoH for a brief period of time and even injure him)
Speed: Average Human, Superhuman with the exosuit ( Kirito with the exosuit) | Subsonic (Should be comparable to other front line players by this point in the game) with Supersonic reaction speed (Should be comparable to Kirito and Asuna, who are able to react to Flashing Penetrator) | Supersonic+ combat speed and flight speed (Should be comparable to other ALO players, who can somewhat keep track of Kirito's movements) | Superhuman (Should at least be comparable to Kirito and Eugeo during the Human Realm Arc). Subsonic with YUNA (Able to keep up with PoH)
Lifting Strength: Average Human, Peak Human with the exosuit (Picked up and threw Kirito effortlessly with one hand) | Possibly Class 5 (Should be vaguely comparable to Kirito by this point) | Possibly Class 5 (Should be comparable to other characters from SAO by floors 30-40) | Superhuman (Should be comparable to Kirito and Eugeo during the Human Realm Arc). Superhuman with YUNA (Superior than before)
Striking Strength: Human level, Street level with the exosuit | At least Small Building level | Building level+ | Building level. At least Building level with YUNA
Durability: Human level, Street level with the exosuit (Jumped from a tall ledge of a building to the ground without any problems whatsoever) | At least Small Building level | Building level+ | Building level. At least Building level with YUNA
Stamina: Average, likely Superhuman with the exosuit (Has not shown to be tired in any of his fights) | Infinite physically (Virtual Reality Avatars can never get physically tired; limited only to the mental power of the person themselves), Normal Human mentally. Superhuman mentally post-Cordial Chords (Managed to break free of paralysis created by a malfunction in the NerveGear itself— something that should be impossible to fix— through sheer willpower) | Infinite physically (Virtual Reality Avatars can never get physically tired; limited only to the mental power of the person themselves), Superhuman mentally (Same as post-Cordial Chords) | 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 (Continued to fight even after both of his arms were cut clean off and was able to feel the full pain of it)
Range: Standard Melee Range, Extended Melee Range with a sword in AR | Extended Melee Range with a sword, several meters with dash-type Sword Skills | Extended Melee Range with a sword, several meters with dash-type Sword Skills and Magic | Extended Melee Range with a sword, several meters with dash-type Sword Skills
Standard Equipment: Exosuit, the Augma | An unnamed sword
*The Augma: A device that allows the user to use Augmented Reality technology. Real life only.
Intelligence: Eiji is an excellent hand to hand combatant and sword user, being able to keep up with, and was handily beating Kirito for most of their fight, who at that point had 2+ years of combat experience with unarmed combat, weapons, and in Kendo. Expert in grapples, sweeps, acrobatics, and other practical martial arts techniques. Other than that, he's average academically.
Weaknesses: The exosuit core can be ripped off the back of his neck, making the suit stop working | Sword Skills have a small post-motion delay at the end of them in exchange for increased power. 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. If he believes that he's in any sort of danger, he will be paralyzed (Resolved post-Cordial Chords) | Same as before | Same as before
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.
*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, . Also note that these may not be all of Eiji's Sword Skills, but simply most of the ones he has been shown to use. Cannot be used in Real Life/Ordinal Scale (Can only use imitations).
*(SS) Horizontal: Slashes horizontally.
*(SS) Slant: Slashes diagonally.
*(SS) Vertical: Slashes vertically.
*(SS) Sonic Leap: A Sword Skill that makes the user charge at the target at high speeds. It can be aimed at the sky as a jumping attack.
*(SS) Vorpal Strike: A high-speed thrusting attack done with one-hand swords and makes a jet engine-like noise when used, so it is not a very subtle attack. It has a notably longer post-motion than other Sword Skills.
*(SS) Vertical Square: A 4-hit Sword Skill that slashes four times vertically. After the skill is finished, a square, drawn with the four hits of this skill, continues to spin as it dissipates.
*(SS) Horizontal Square: A 4-hit Sword Skill that slashes four times horizontally. After the skill is finished, a square, drawn with the four hits of this skill, continues to spin as it dissipates.
