Bored of her immortal life on Earth, Kaguya Houraisan decides to board the mining ship Red Dwarf in hopes of regaining an interest in life by exploring deep space. But when she exits stasis after a radiation leak wipes out the entire crew, she's left only with her fellow immortal, Fujiwara no Mokou, and an AI version of her mentor, Eirin Yagokoro, to drift together in space forever

The Hourai Elixir returns you to a "perfect" state : no pain, no marks, nothing. Yet over time, you want control over yourself. You want to be able to keep your cuts, your burns. You want proof of what you've lived through. Eternity strips you of all that. Together, Kaguya and Mokou rebel against the restrictions of Eternity the only way they still can : through pleasure and pain.

"Hello. My name is Kyubey. And I can grant you one wish." But at what cost are those wishes granted? Kyubey certainly isn't above waiting for the perfect moment, the one where you're at your most vulnerable, to strike. Because once you've hit rock bottom, you'll take any wish - even if you know you'll regret it. (Mostly OC; this serves as the backstory for my character for a RP)

One cold winter morning, Maribel Hearn and Renko Usami's bus finds itself transported into the strange yet familiar world of Maribel's dreams. Yet this time, it isn't a dream. What can you do when you're trapped in a nightmare and can't wake up ? As Maribel's perception of dreams and reality starts to blur, will Renko be able to save her friend from losing herself ?

An immortal needs distraction in their life. Mokou, who had served as Kaguya's distraction for centuries, has disappeared, and Eientei's slow pace hasn't been enough for her. When she finally does return, however, she brings with her a torrent of memories surrounding her immortality and the difficulties she has lived through because of it.
