I Walk Between the Pages of Type-Moon History

I once crossed the peak of the Bakumatsu alongside Okita Souji. I once shared in the splendor of Mount Ooe with Shuten. Amid the flames of Honnoji, I witnessed a girl become a Demon King. On the ruins of Britain, beneath its final curtain, I fought with wild abandon. I thought I was walking between history and mythology. And now you’re telling me I’m in Type-Moon? Excuse me??? (The events in this synopsis aren’t in story order. If you’re not familiar with the setting, expect plenty of alternate interpretations.) (P.S. I’m just borrowing the worldbuilding to tell the story I want to tell.)
