Rei, a former samurai lieutenant is reincarnated into the body of an 8 year old, who happens to be the main villainess in a romance novel for foreign girls. A villainess destined to be executed by her fiancé the crown prince for cruelty towards the heroine of the novel. To avoid being executed she must to make allies among her enemies, get out of the heroine's way, and untangle herself from the poisonous intrigue of court the best she can in the role of a future courtier. However, the vaguely described backdrop said nothing about the conflicts building beyond the heroine's understanding, or that women weren't allowed on the battlefield. I am honestly left speechless. I am very touched and honored by all the attention, by all the sweet, beautiful and fun comments I've received over the last month, it's been truly amazing. To those who already enjoy it, I hope you will continue to do so. To those who decide to pick it up, I hope you have as much fun with it as I did!

He died. He used to have a happy family but that's no more, he couldn't reverse the time and undo his death. But even something miraculous would happen to him, a reincarnation. That's a nice thing. However, he was reincarnated as someone who didn't remember his past and had no family. He was living an empty life with no clear purpose until he met two girls... Kanae and Shinobu. And knowing that he reincarnated in the "Kimetsu No Yaiba" world. He was determined to change the future and to stop the tragedy, he swore to himself that he would protect both of them. He joined the demon corps and with his prodigy mind, he created a unique breathing technique that couldn't be passed down and only he could use it: "Ice Breathing". With the sensation of coldness, he slayed demons and rose to the top as the "Ice Hashira". P.S: Third reboot and it's the final reboot. Trust me.
