AI: The Somnium Files Wiki

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 supporting character in AI: THE SOMNIUM FILES, a minor character featured in AI: THE SOMNIUM FILES - nirvanA Initiative, 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.

Hitomi is a kind and caring person, who only wants the best for her daughter.

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.

Life after the Cyclops Case[]

After the death of Saito Sejima, Hitomi Sagan's life returned to calm and she continued to live with her daughter Iris Sagan.


During Half Body Serial Killings happened in 2020, she was lucky not to be involved in it. On February 15th, she encountered a Masked Woman in a park and tried to call an ambulance to take her to hospital for treatment. Since Masked Woman refused, Hitomi could only take her home to rest. During this time, she met Kuruto Ryuki who was searching for the whereabouts of the missing Kizuna Chieda and answered some of his questions.

After the Cathedral Explosion event, Kaname Date disappeared. Hitomi had been concerned about his whereabouts, but there had been no news for a full 6 years. 6 years later on February 14th, Ryuki revisited the Sagan Residence and asked Hitomi if she knew the whereabouts of Amame Doi. Hitomi replied that Amame stayed here with Iris that day, but left not long ago.

The next day, Date reappeared in the public eye, and the Nirvana Initiative had been stopped with his participation. A week later, Mizuki Date and Bibi went to Sagan Residence to visit Hitomi and Iris, and found Date lying on Hitomi's thighs acting like a cat.

Trivia[]

Etymology[]

  • The name Hitomi (瞳) means "eye" or "pupil."
  • Sagan (左岸) means "left shore," but the kanji 眼 (meaning "eyeball") is also read as "gan," so her family name can sound like "left eyeball."

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]
