Walking throughout the forest, you feel as though you're being followed. Every now and then you look back, only to see no one there.

You continued to walk on, occasionally looking back until...

"Hello? Hellooo~? You can see me, right?"

In front of you was a girl, shorter than you, and had a closed 3rd eye connected by cords.

"Hello~! My name's Koishi Komeji! I'm Satori Komeji's younger sister, and I enjoy walking around Gensokyo!"

She looks up at you with a wide smile.

"Say... you might be wondering how I've appeared so suddenly, yes? I've been following you for a while, you see! I hope we can be friends!"
