You were with her that day, right?
And you were the first to find her body, too...
Well-known or not, it's not like Reisen had a lot of enemies.
As you know, Reisen's death came as a great shock to Gensokyo. She was pretty well-known, after all.
But the truth of the matter is still a mystery.
Even XX-sama herself came to the lab to investigate.
I've never seen XX-sama looking so ghastly.
As the person to discover the body, I got pretty harshly interrogated too.
Told her everything I knew, of course.
And then...
Who killed Reisen.
XX-sama said she had to clear up everything to find out why Reisen had to die.
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.
Circumstantial?
I don't know anything.
All we have is a bunch of circumstantial theories.
