[Crossover] Has the World's Greatest Left Yokohama Today?

Hello, I'm an utterly unremarkable swordsman. After spending ten boring years as the greatest martial artist under heaven, I shattered the void on my twenty-ninth birthday.

The new world beyond the void gave me a grand welcome. The moment I stepped out of the space-time passage, a terrifying black flame blasted me away, even as I bore the wounds carved into me by the currents of space and time.

To protect myself, the long sword that had been with me for years turned to ashes. What a terrifying new world.

1. The male lead comes from the modern world, enters a wuxia world, then shatters the void and arrives in the Bungo Stray Dogs world.

2. The pairing is with Rimbaud, not Randou. He is the original Verlaine, the one Asagiri has not described. If Asagiri adds new information later, I may revise this, but probably not.

3. Rimbaud's characterization is based on his real-life biography, his poetry, and the film Total Eclipse. Different people have different interpretations, so their depictions will differ too.

4. In the story, Rimbaud is referred to as Arthur in the pairing, while the other Rimbaud is referred to as Rimbaud/Randou.

5. This is a very short story, and it is complete.

Theme: Everyone is chasing their own light. As long as you keep going and never give up, you will eventually embrace your own sun.
