File No. 021 Shu Amiguchi 網口愁

網口愁（あみぐち しゅう）は家が金持ちでスポーツ万能のプレイボーイ。軽薄だが人当たりがいいため男女ともに人気がある。本心では世の中に退屈している一面をもつ。

Shu Amiguchi is a popular kid from a rich family. He's a decent athlete, and kind of a playboy. Despite his flippant attitude, he's friendly and well-liked across the school. Deep down, he's mostly bored and tired of his life.

偶然通りかかった商店街で、輪島達に絡まれている鷹宮由貴を目撃して助け出した。網口は彼女の可愛さと腕っぷしの強さに惚れ込むことになる。

While in the shopping district, he happened across Yuki Takamiya getting harassed by Takemi Wajima and his gang, and helps her out. Amiguchi ends up falling for her, smitten by her cute looks and tough attitude.

最近よく見る不思議な夢と、テレビから話しかけてくる謎の少女の件で悩んでいる。

Lately, he's been struggling with strange dreams, and an even stranger girl who's been talking to him through his TV.

網口が見る不思議な夢の正体は、網口と同じ顔を持つ井田鉄也が体験した過去の出来事だった。因幡は「箱舟計画」を守るため、井田の考えを知りたいと語った。

The strange dreams that Amiguchi has been seeing were actually the past experiences of Tetsuya Ida, who looks near-identical to him. In order to protect "Project Ark," Miyuki Inaba expressed that she wants to learn his thoughts.

保健室にあったカルテによると網口に投与されたのはナノマシンの薬であるNM:A8076 で投与は一回、移植率20％とだけ記載されていた。

According to the medical records in the nurse's office, Amiguchi was administered a nanomachine medication called NM: A8076 once. The records also stated there was a "20% transplant rate."

網口は井田と同じDNAを持っており、森村によって井田の16歳から26歳までの記憶を移植されていた。また、井田が赤ん坊だった網口をセクター4（1980年代）に連れてきて網口家に預けた。

Amiguchi, who is genetically identical to Ida, was having Ida's memories from between ages 16 and 26 transplanted into him by Morimura. Moreover, Ida brought the infant Amiguchi to Sector 4 (the 1980s) and placed him into the Amiguchi family.

屋上で網口が薬師寺から銃で撃たれた際、20番機兵が起動した。網口は以前、商店街で出逢い、緒方によって気絶させられてしまった三浦を自宅まで運ぶ際に、三浦と接触していた。そのため網口は、沖野によって三浦に仕込まれていた機兵強制起動コードの影響を既に受けていた。

When Amiguchi was shot by Megumi Yakushiji up on the rooftop, it activated Sentinel No.20. Prior to this, Amiguchi had already come into contact with Keitaro Miura when he had to carry Miura back to his house after Nenji Ogata's altercation at the shopping district. For that reason, Amiguchi was already affected by the force activation code for Sentinels that Tsukasa Okino embedded into Miura.
