In the distant future, a gigantic energy mass called the “Star of Destruction” suddenly appears near Mars. Its presence causes abnormal weather and tectonic plate shifts on Earth. As resources become scarce and populations have nowhere to go, conflicts erupt worldwide. This, however, is merely an omen of things to come.
Only a hundred years remain for humanity. They plan to evacuate the planet to evade its doom. Two projects are drafted to meet that end.
First is the establishment of Earth’s Unified Government, which will allow the project to be implemented. Evacuating Earth becomes a top priority, and the order of “sacrificing the few to save the many” is implemented. Authoritarian rule controls the masses. Armed force oversees states and non-governmental organizations that oppose the new world order. The overwhelming military power maintains order regarding race, religion, food, energy, etc.
The second is the “Felix Project,” which will serve as the foundation for the exodus plan. With only 100 years left, humanity needs to build a spaceship to leave the planet and acquire the technology to survive in the vacuum of space for a long time. They decided to create “Felix,” genetically modified people with extraordinary intelligence and longevity. These “superhumans” will be able to complete the seemingly impossible project.
99 years pass.
A lone female Felix, Sion, has served her role as the central figure in the Earth Evacuation Project. With her job completed, Sion wishes to spend her remaining time quietly on the abandoned Earth. A young man, Ryo Haruna, from the unified military, is deployed to her side to protect and keep her in check.
Their meeting sets the story in motion.
The final love story on Earth.

























Hi guys, just wanna ask if i buy the steam ver. but i replace the exe. file from the R18 patch is it possible? If it doesn’t work, just gonna get it on steam, planning to support dev team ^^
and regarding the file part 3, has it been deleted?
You can’t download more than two files at once as a free user. If you’re getting “file not found” errors, wait until previous parts finished downloading before starting 3rd one.
eheh ^_^||| didnt thought about that limitation for a free user..and admin-san, regarding the replacement of the exe files..will it work?
is this one good? … i have read like for 5 hours now and i cant just get engaged by it, the miusic is cool, but it makes me sleepy and like not want to continue reading… so… is it worth?
Is this archive works? Is need an emulator or is for pc even?
Hi, thanks for the work on this site, Admin!
Playthrough was amazing, music was in the same mood as ef, and I held it up to those standards.
I have a problem regarding the H-scenes in Plus Mosaic, though. Are they all supposed to be black? I didn’t see an option in the configuration menu, nor do I remember seeing a choice between all ages/adult (having read this over the span of 6 months or so, memory is a bit hazy.) in the beginning. Am I supposed to run through all 4 scenes before they unlock, or something like that?
is anyone here who have the download lik for this game OST? I’m just asking
Anyone have 100% save file of this game?
play the game nigger
Man, I bought this game on Steam and played it through completely, and damn it, after 12 hours of reading, bottling up emotions, crushing those emotions and going back to reading, I finally finished it and then cried my eyes out for a hour straight, yeah, non manly but fuck, that was a depressing ending. Even more than Plastic Memories.
I must admit. . . . this is seriously heart rending. The beginning alone was quite sad enough but the ending. . . . it just wants to make you cry…. i cried a lot at Plastic Memories because I watched it not knowing what I was getting myself into but this. . . . . Its too much …..
does this contains h scenes?
Yes, but an all age version is available for purchase on steam if you don’t want them
i downloaded it but it said that “save directory creation fail. program will exit”, can anyone help
Scanned it on virustotal apparently one picked it up as a Malicious.moderate.ml.score is this a false positive?
The CGs are nonexistent, im angry.
