A Kinetic Novel created by minori, who also created ef - a fairy tale of the two..
In the future, a red star in the sky signifies impending doom for planet Earth. To prevent the end of the world, genetically modified humans with staggering intelligence called felixes were created. The most intelligent of these, Sion, engineered the plans for the Earth Evacuation Project, and humanity was gradually sent into space to save them from Earth's destruction and to continue the footprint of humankind.
When the game begins, the fate of Earth draws closer. Sion resides at a research facility on a lone island, continuing her work. Our protagonist, a warrant officer named Ryou Haruna, is assigned to guard her, and from there, a mysterious and sad story unfolds.
This game provides examples of:
- A-Cup Angst: Sion is self-conscious about being less developed than the other felixes.
- The Alcoholic: Inaba shows some signs, with his tendency to drink during the early afternoon.
- Almighty Janitor: Elica practically runs the research facility, despite being a maid.
- Anyone Can Die: Most of the cast is either dead or set to die before the game is over (the only exceptions being Maya and Lavie.)
- Aren't You Going to Ravish Me?: Sion gives permission to Ryou to fool around with her in her sleep as her health starts to deteriorate. She seems disappointed when he doesn't take her up on her offer.
- Artificial Human: Felixes - humans made to have a longer lifespan and a greater intelligence than the average person.
- Big Good: Sion is certainly this; being the one who engineered the plans for the Earth Evacuation Project, and as the result, humanity was gradually sent into space to save them from Earth's destruction and to continue the footprint of humankind.
- Bittersweet Ending: Sion got to live out her wish after saving humankind with her work, Ryou got to be with her in her last days, and Maya and Lavie were on the evacuation ships that transported the rest of humanity to space...but Inaba and Elica were killed and Ryou is left as the only remaining human on an Earth about to die, after watching Sion pass away.
- Chekhov's Gunman: Maya is mentioned fairly early on by Inaba, as a reporter who is being very persistent in her attempts to interview Sion. She enters the story when she finds Ryou and Sion at Ryou's childhood home thanks to instructions from Lavie.
- Cool Big Sis: Elica basically took Sion on as a sister, and their genetics are similar enough that they can reasonably call themselves that. Natsume also styles herself as a big sister to Ryou.
- Damsel in Distress: In Maya's backstory. She was kidnapped because her father was a government official; the event was what made her decide to become a journalist.
- Dissonant Serenity:
- Ryou and Lavie like to have calm, casual, perfectly pleasant conversations about how they killed their respective assassination targets.
- Elica when she tells everyone in the facility that she's about to blow it up.
- Face of a Thug: While Ryou isn't unattractive, his dark and brooding eyes tend to scare some of the cast.
- Gilded Cage: The research facility is actually the home where Sion was born and raised, and she has never been permitted to leave. The same goes for the other felixes born there, including Elica and Natsume.
- Go Out with a Smile: Sion dies with a smile on her face while overlooking the lake.
- The Hero: Ryou Haruna fulfills this role, as he is assigned to guard Sion and help protect humankind.
- I Choose to Stay: In the end, Ryou forgoes his last chance to leave Earth and instead chooses to stay with Sion until her death.
- Intrepid Reporter: Maya sent Inaba tons of emails begging to see Sion, and even climbed up a mountain riddled hill just for the chance to meet her in person.
- Just Before the End: While they don't know why, all scientists agree that the world is going to end very shortly. Evacuations have been going for a while to save humanity.
- Meido: Elica wears a maid uniform.
- My Greatest Failure: Inaba hates that he could never save Natsume. Helping Sion escape with Ryou is the closest thing he can do to atone.
- Older Than They Look: Felixes stop aging at around age twenty; Sion's growth stopped earlier than normal, possibly due to an error in her genes.
- Posthumous Character: Natsume is revealed to have died shortly after returning to the research facility.
- Public Execution: Inaba is executed for letting Sion escape; since the facility and its purpose are top secret, his death sentence is officially for the murders of the soldiers who had been sent to the facility as spies.
- Scenery Porn: It's no surprise that Sion likes the surrounding mountains and lake so much.
- Sexbot: Sion implies that felixes who don't make the grade as scientists are used as these for visiting dignitaries.
- Shipper on Deck: Maya loves Ryou and Sion's relationship. She kisses Ryou in large part to make Sion feel jealous.
- Shout-Out
- The term "felix" is derived from the name of the main character of Robert A. Heinlein's novel, Beyond This Horizon.
- When Sion wishes to tell her entire life story to Ryou, she compares herself to Scheherazade, the storyteller in Arabian Nights. This is an allusion to the felixes' long life spans.
- Sleepyhead: Sion always sleeps in, and can barely manage to wake up in the morning. It takes a darker streak when she stops waking up.
- Together in Death: Elica manages to send a lock of her hair so that she can be buried with Sion.
- What Beautiful Eyes!: Ryou often describes Sion's large, clear eyes. His descriptions get more flattering the more he falls for her.
