I Transmigrated into the Honkai World, and My Stand Is Kallen?

Transmigrating isn't rare these days, so it makes perfect sense that I transmigrated too, right?

But what I don't understand is, why did I become a Stand user after transmigrating into the Honkai world?

What does a Stand have to do with Honkai, anyway?

And why is my Stand Kallen?

I'm not Otto, that Kallen fanatic!

Years later, Jiang Ming stood with his arms crossed, more than a dozen girls behind him, facing the culprit who had brought Honkai into the world.

"Come fight me one-on-one! I'll even fight you with both hands behind my back!"
