(Gintama) The Yato and Alice

While in Yoshiwara, Kamui wanted to see what the woman who had captivated the Night King was like. When he opened the door, he found a cool-faced, brown-haired "girl." As the highly skilled Alice wandered through a dream, she encountered the ferocious Mr. Yato. A worthy match, they clashed as two powerful opponents. 1. A short story, complete in fewer than ten chapters. 2. Matsudaira Rin (not really) x Yato Kamui. That's right, even though the protagonist is a woman, she's totally the dominant one! 3. The heroine dresses as a man for the long term. It looks like danmei, but it's actually a romance. P.S. This was an idea for a spin-off that suddenly came to me while writing "(Crossover) Nohara Rin's Ambition." The expanded and rewritten version can be found in the Gintama arc of "(Crossover) Nohara Rin's Ambition," though the two are basically different stories.
