The Yuri Parable

This is the story of a girl named Yuri. Yuri was a schoolgirl like any other; she would go to classes, have lunch, and meet with her friends in the literature club. While she didn't deem her life as particularly exciting, it was interesting enough for her. After all, she had plenty of things to do: Expand her knife collection, try new types of tea, and explore the world of poetry. At this point, it didn't matter what Yuri's future held for her, or how her past treated her. What matters is that Yuri... was happy.

But then one day, something peculiar happened...
