[Anime Crossover] 818: The Blade Maniacs Under My Command

I couldn't resist starting a story about a little knife spirit. A dark Honmaru, writing whatever I want, letting my imagination run wild. A comedic, snarky take. The heroine might be a “little” silly. The overall message is probably to believe in the goodness of the world and for everyone to turn over a new leaf together. The male lead might follow a side route.
