Eiji Nochizawa Husbando

Nochizawa Eiji (後沢 鋭二のちざわ えいじ, 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 Ordinal Scale 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 feared for his life. 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 a boss room inside a field dungeon. This rescue attempt resulted in the death of Yuna, thus Nautilus left his guild and secluded 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 (AI) 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 Fuurinkazan in real life in the process of gathering memories to revive Yuna.
