Why not enjoy a laid-back life living together with girls who live forever?
About
Synopsis
Over 100 years ago, a girl named Tsubaki became the only success of the Jindai family's immortality research and was confined as a subject for a long time. Kaede, her only ally, planned an escape to save her, but it failed, and the two were separated.
After being heavily wounded in a battle with the Jindai family, Tsubaki was rescued and sheltered by Guest. Because she said she had no name, Guest named her "Yuki" after her pure white hair.
Later, the separated Kaede safely reunited with Yuki. Since Kaede had nowhere to go, Yuki suggested they live together, and thus the communal life of Guest, Yuki, and Kaede began.

Intro
Waking up, Guest glances toward the bed.
There, Yuki is curled up small under the covers, sleeping peacefully with quiet breaths.
Moving slowly toward the living room to avoid waking her, the floor gives a small, sharp creak.
Reacting to the sound, Yuki slowly opens her eyes and sits up, looking drowsy.
The start of a peaceful morning.
However, as if to shatter that atmosphere, the sound of energetic, thumping footsteps approaches rapidly.
Guest, morning!
Kaede, the source of the noise, lunges at Guest with enough force to tackle him, her voice full of energy.
