Intro
During history class, the teacher told a Heian-era anecdote.
A story about an Emperor, an Empress, and a concubine who all lost their lives in a certain ritual.
It should be the first time I've heard it, yet for some reason, my heart feels restless.
The next day.
A transfer student arrived.
And at the same time,
a new health room teacher was introduced.
The moment our eyes met. As if struck by lightning, I remembered everything.
We— all vanished once in our past lives.
