Ever 17 Timeline
1992 Leiblich Pharmaceutical undertakes the development of LeMMIH.
Tanaka Yoichi (You's father) is employed as a technician to develop LeMMIH.
December 3 - Tom Faiblin is born.
1993 July 5 - Komachi Tsugumi is born.
1996 (Date unknown) Kuranari Takeshi is born.
Yukie (You'haru's mother) is employed by Leiblich Pharmaceutical.
1997 (Date unknown) Kuranari Takeshi is born. (Takeshi is born either in 1996 or 1997)
1999 (Date Unknown) Ishihara Makoto is born.
March 30 - Tanaka Yubiseiharukana is born.
April - Leiblich Pharmaceutical establishes the submarine IBF research laboratory
June 15 - Japanese government starts a plan to develop and populate the Komagahara Archipelago.
Oceanic Science Center starts the third plan for living under water.
Those two plans handled by the government happen to be in sync with Leiblich's own agenda.
With the help of strong industries, financial institutions, and the government itself financing it, LeMU Corporation is established with Leiblich Pharmaceutical controlling most of its stocks.
2000 May - Yoichi learns that Leiblich Pharmaceutical is developing the Tief Blau virus.
Yoichi disappears. (Leiblich Pharmaceutical detains him)
2001 June 14 - Kaburaki Suzunori (Kaburaki Ryogo) is born.
2002 December 17 - Yagami Coco is born.
A physician in Italy declares that a woman is pregnant with a cloned fetus.
Shortly after, a company in the U.S. indicates a cloned baby is born.
After being confirmed, these events become controversial.
(These are widely believed the first cases of cloned humans.)(Human Cloning is a common theme in Infinity and is discussed in moderate detail in Never 7 and Ever 17. These events present a background story in this universe.)
2004 April - Construction of LeMU begins.
2005 August - Tsugumi, 12 of age, gets infected by Cure Virus from Julia. (Tom first "pass on" the ability to 'heal' to Julia, and later Julia gave this ability--in form of Cure Virus-- to patients in her hospital room. It is still under discussion of how Julia managed to infect Tsugumi with the virus.)
Tsugumi is confined in a Leiblich facility. (At age 12)
2006 Dr. Cabin proposes the "Cure" Hypothesis. (Note that this is not the Cure Virus but rather closely related to Cure Syndrome.)
2007 April - Construction of LeMU is completed and it is open to public.
2010 Cloning Law is revised. (Making You'haru's 'genetic immortality' lawful.)
Tsugumi, age 17, ceases to age due to the effects of the Cure Virus. (Which is five years after initial infection as the game says.)
2011 April 2 - Akanegasaki Sora goes into operation (functioning at a constant age of 24)
2012 An irregularity is discovered in the base sequence of Julia's DNA, sending a shockwave through the world of science.
2013 December - The uproar surrounding Julia gives credibility to the idea of a Cure Syndrome.
(Of that Tom spread his ability to heal, presumably)
Tsugumi escapes from the Leiblich facility and lives as a fugitive on the run.
You'haru collapses.
She is diagnosed with a serious heart condition and is expected only to live 3 to 4 years.
2014 October - An unknown virus is discovered in Julia's blood and was named "Cure Virus." (This should be the first time when the existence of the virus is published.)
At a point of utter despondency, You'haru meets Dr. Morino Shigezo
December - You'haru has her "new self" placed inside her womb.
2015 September 22 - You'haru gives birth to Yubiseiakikana.
2017 April - You'haru enters Kyumeikan Women's University
May 1 - [Ever 17 / Takeshi Perspective]
Takeshi, You'haru, Tsugumi, Coco and Kaburaki visit LeMU.
An accident occurs and the Tief Blau Virus is spread from IBF.
A TB contagion starts.
May 6 - Yoichi dies in IBF.
May 7 - Tsugumi is pregnant. (Takeshi is the father, naturally.)
Coco and Takeshi placed themselves in a state of induced hibernation at IBF.
Sora (LeMMIH) stops operation.
You'haru, age 18, and Kaburaki, age 15, are infected with the Cure virus. (By injecting the vaccine made from Tsugumi's blood.)
LeMU implodes.
Tsugumi resumes her fugitive life.
You'haru is contacted by Blick Winkel (BW) and learns the truth.
She persuades Kaburaki to prepare for the plan to summon the Third Eye.
Tief Blau, Bio-Hazard Level 4, spreads around the world.
2018 January 21 - Tsugumi gives birth to Sara and Hokuto
October - LeMU restoration completed. (It's unrealistically fast in my opinion...)
Sora (LeMMIH) is rebooted.
2019 The number of Tief Blau victims reaches its peak.
Yukie is also infected, and passes away...
From this point on, TB infects less and less victims.
In order to evade Leiblich agents who are chasing her, Tsugumi places Sara and Hokuto in a seemingly reliable facility.
2020 You'haru completes The Third Eye hypothesis.
2021 April - You'haru becomes a graduate student at Kyumekan Women's University.
2022 You'haru, age 23, and Kaburaki, age 20, cease aging due to the effects of Cure Virus.
2024 World Health Organization declares the TB Virus eradicated.
Sara and Hokuto are captured by Leiblich. (At age 6)
2025 March - You'haru completes her doctoral degree.
April - You'haru starts to work at LeMU Corp.
Kaburaki starts to work at Leiblich Pharmaceutical.
Hokuto is released from Leiblich's facility. (At age 7. He and Sara only lived together under Leiblich's captivity for a year.)
2031 April - You'aki enters Kyumeikan Women's High School.
2033 April - Sara, who enters Kyumeikan Women's High School as a scholarship student, meets You'aki.
2034 April - You'aki enters Kyumeikan Women's University.
May 1st - [Ever 17 / Hokuto Perspective]
Hokuto, You'aki, Tsugumi, Sara and Kaburaki visit LeMU.
You'haru and Kaburaki execute "the Third Eye plan".
BW appears. The Third Eye is found. (This line can be understood as the player starts to interact with Ever 17's world.)
May 7th - They escapes LeMU with You'haru's assistance.
LeMU Implodes.
Miracle of Aphrodite (She's the goddess in Pygmalion's mythology who granted the statue life to please Pygmalion. It is strange to contribute Sora's appearance with a material body to a "miracle" as she is widely believed to obtain a cyborg body.)
Blick Winkel... awakens.
Takeshi and Coco are rescued by BW and Hokuto from IBF.
The connection between Leiblich and TB's rampage is publicized.
Government investigation is conducted on that issue.
Leiblich Pharmaceutical (Japanese Division) is shut down.
LeMU is sold to a civilian company.
Reconstruction of LeMU begins.
