Naruko's Isekai Chronicle in Yokohama

This novel is also known as: "From Demon Slayer to Bungo Stray Dogs in One Sun Breathing" "It's very stressful for a child working at the Port Mafia in Yokohama" "For survival, I've lost all my integrity and am acting cute like a cat in front of President Fukuzawa" "Days as a Young Lady in the Port Mafia" "I'm introducing jobs in Yokohama to the genuine and fake Jintsuu who transmigrated from the Wine Factory" "What to do when Teacher Fukuzawa becomes a child?"

I am Uzumaki Naruko. Not long ago, I was in the village preparing to attend my older brother's wedding, and in the blink of an eye, I transmigrated into the world of Demon Slayer.

Don't panic! The Will of the World has already made a deal with me. As long as I save this world from being destroyed by demons, it will send me back to Konoha.

What a load of crap! (╯‵□′)╯︵┻━┻ This dangerous world, transmigrating into a loli without chakra, means instant death! The worst part is that to save the world, I either have to kill the 'trash boss' four hundred years early or… give birth to the ancestor of the Mist Hashira while they were still human… I should probably focus on finding a way to kill Muzan in the Warring States period!

The only thing that brings me solace now is that I transmigrated as Uta, yes, the future wife of the combat ceiling of Demon Slayer. Seeing Yoriichi's adorable little face, I immediately felt like I could do this again! What are demons? Once I take down the trash boss, I'm going back home to get married!

Of course, before I can kill Muzan, I need to solve a few minor issues – namely, finding a way to get Yoriichi and me back from Yokohama! This world, with its constant explosions during broad daylight, is even more dangerous than the world of Demon Slayer! Ahhh!!!!
