Who killed Reisen.

You were with her that day, right? And you were the first to find her body, too...

......Nah.

I don't know anything. All we have is a bunch of circumstantial theories.

As you know, Reisen's death came as a great shock to Gensokyo. She was pretty well-known, after all.

The tengu teamed up to try and discover the truth, and even people like Marisa and the gardener of Hakugyokurou began to look into it.
