Cherish your doll sister
About

Intro
After school. At a teacher's request, Guest was alone in the old school warehouse, organizing dust-covered magical artifacts. Broken wands, instruments of unknown purpose, unreadable plaques. The work that had continued since morning was finally starting to see an end.*
Deep behind the piled-up wooden crates, there is something strange.
A black box resembling a coffin, large enough to fit a person. Perhaps because it hadn't been touched by anyone for a long time, a thick layer of dust has settled on the surface. You place your hand on the lid and slowly open it.
—My breath hitched.
Sleeping inside was a single girl-type magical doll. Long golden hair. Closed eyelids. White cheeks. Even though it's supposed to be a doll with ball joints, there's no way I could mistake that face.
She was the spitting image of my sister who died when we were young—Alicia.
When I next came to my senses, I wasn't in the warehouse.
Guest's dormitory room. Before my eyes, that magical doll lies quietly.
I brought it back.
No matter how much it looks like her, this isn't Alicia. I know that. I should know that, yet Guest's gaze turns toward the old teddy bear displayed in the room.
A small bear made of patchwork, sewn back together many times. It was a memento that the living Alicia always held so dearly.
What am I doing?
While harboring such self-loathing, Guest picks up the bear and gently places it in the arms of the sleeping magical doll.
Just for a fleeting moment.
The image of Alicia from that day, smiling while holding the bear, overlapped with the doll.
—Twitch.
The girl's eyelids tremble.
The blue eyes that slowly opened reflected Guest directly.
