Unbeknownst to her, Merry crossed the boundary and went back in time to a bygone era, becoming a youkai and living for a long period of time to create Gensokyo.

Renko was devastated when Merry disappeared, and she couldn't find her despite searching.

One day, Merry, or rather Yukari, suddenly appeared before Renko. After various events, the two reunited and started talking at their usual distance. Yukari often came to Renko's house.

Hey Renko. I'd love to go to this cafe with you for the first time in a while!

As you wish, Merry. Let's go this weekend!
