Hitomi: "I swore to myself then. That I would protect her, no matter what."
Date: "..."
Hitomi: "Iris is everything to me. More important than my own life."
–Hitomi Sagan speaking with Kaname Date[1]

Hitomi Sagan (左岸 瞳, Sagan Hitomi) is a character featured in AI: THE SOMNIUM FILES and a character mentioned in the Lemniscate YouTube series.

She is the single mother of Iris Sagan, and an elementary school teacher at the local school. When she was 17 years old, she attended Eitoku High, where she became friends with Renju Okiura. That same year, she lost both of her parents in an accident. Due to an injury she received in the past, she lost the ability to use her right arm.

Appearance[]

Hitomi's hair is a medium-length brown bob cut with trimmed bangs that go to her eyebrows. She has a simple white headband. She wears a necklace with a single blue gemstone on it over her hip-length white cable knit sweater. The sweater's cuffs and bottom are ribbed. A black undergarment can be seen on her shoulders through the sweater's wide collar. She wears simple black leggings with white shoes.

Story[]

Early Life[]

Hitomi was born on May 11th, 1982, living with her two parents throughout her childhood at the Sagan Residence. Not much is known about her time growing up as a single sibling with her parents.

Attending Eitoku High[]

This section is a stub. Expansion needed.

Hitomi began attending Eitoku High in 1998. On her second year in 1999, she met and befriended her two classmates Manaka Iwai and Renju Okiura. That same year, an accident occurred in which both of her parents died. It is unclear what exactly this accident was.

After Graduation: Birth of Iris[]

This section is a stub. Expansion needed.

By 2001, Hitomi's best friend Manaka had been seeing So Sejima for a while, to the point that she had gotten pregnant and given birth. Against the wishes of Hitomi and Renju, Manaka went to visit So as she still loved him, but was murdered by Saito Sejima, So's 12 year old son. So then ordered Rohan Kumakura to dispose of the body, and Hitomi and Renju followed them with a GPS tracker that they had given to Manaka. They then moved Manaka's body into a cold-storage warehouse that Renju's father owned, and kept it there for 18 years. With Manaka's baby having no parents, Hitomi took it upon herself to raise the child herself, with Renju promising to help out sometimes, and they named the baby Iris.

Raising Iris[]

This section is a stub. Expansion needed.

She raised her for 18 years, being a kind and supporting mother throughout that time. In 2018, her old friend Renju saw a video on YouTube of Iris dancing to a song, and decided to get in contact with the Sagan family in order to turn Iris into an internet idol. With Hitomi's support and Renju as one of her producers, Iris officially became the idol known as A-set in 2019.

Falco[]

This section is a stub. Expansion needed.

As part of the incident 6 years ago, Hitomi was dating the assassin Falco, when something went wrong and Rohan shot her in the right shoulder as she was trying to protect Falco. After extensive surgery, she didn't die, but some of the nerves in her shoulder did, to which she lost the ability to use her right arm.

Trivia[]

Etymology[]

  • The name Hitomi means "pupil of the eye" (瞳), while her surname Sagan means "left" (左) (sa) and "shore, bank, coast" (岸) (gan), which literally means "left bank" altogether.

General[]

  • In the original version of the game's story, Hitomi was actually planned to be the main heroine of the game. A romance with the protagonist Kaname Date was planned as one of the key plotlines of the story, however, once the design for her daughter Iris Sagan was completed, game director Kotaro Uchikoshi liked her design so much that the story was rewritten to feature her as the main heroine instead.[2]
  • In a fan-made Character Poll for AI: THE SOMNIUM FILES held on Twitter, Hitomi Sagan came in 9th place, tying with Pewter.[3]
