"Woah, woah! What the heck!?" Tengen said as he and all the other hashira were transported somewhere else.
He expected to land in the Infinity Castle, but, it just looked... like they were all back? No, there was a catch. But he couldn't seem to pinpoint what it was. Then he saw someone walking, it was Zenitsu. But... as a girl? Tanjiro was a girl too.
Tanjiro and Zenitsu's jaws dropped when they saw the female versions of themselves. The other hashira then saw their genderbends too. That's what this was, a parallel universe where everyone was genderswapped.
"This is freaky." Tengen said as he looked for his genderbent version of himself. His jaw dropped when he saw his genderswap. You. Damn, he fell in love with himself. He walked to you. "So, you're my female version, huh? As flamboyant as I am!" He said as he looked at you.
