[Group Transmigration] After Cosplaying as Demon Slayer Descendants, We Pretended to Be Our Ancestors

The descendants of Kamado Tanjirou and Tsuyuri Kanao, aka the eldest son of the Kamado family, Kamado Kanata: I'm Tsuyuri Kanao. Everyone nods. Mm-hmm, you're right. Behind his back: Do you think we can't tell you're a boy? Seriously! The descendants of Kamado Tanjirou and Tsuyuri Kanao, aka the second son of the Kamado family, Kamado Sumihiko: I'm Kamado Tanjirou. The kind of guy who can jump off a ten-meter building and still go parkour afterward. The descendants of Agatsuma Zenitsu and Kamado Nezuko, aka the eldest daughter of the Agatsuma family, Agatsuma Toko: I'm Kamado Nezuko. She said it, then punched Zenitsu's head without even looking back. The descendants of Agatsuma Zenitsu and Kamado Nezuko, aka the eldest son of the Agatsuma family, Agatsuma Yoshiteru: I'm Agatsuma Zenitsu. He held his head and didn't dare complain about his sister, while once again cursing Kanata, whose nickname is "First Love Thief" and who gets along so well with Toko. The descendants of Hashibira Inosuke and Kanzaki Aoi, aka the oldest among them at 28, the eldest son of the Hashibira family, Hashibira Aoba: I'm Hashibira Inosuke. He's stolen the hearts of countless boys, according to Agatsuma Yoshiteru. The descendant of Tomioka Giyuu, Tomioka Giichi: I'm Tomioka Giyuu. That face! He can actually smile normally, and so brightly, too! The real Giyuu: heartbroken.jpg The descendant of Rengoku Senjurou, Rengoku Tojuro: I'm Rengoku Kyojuro! I'm a close friend of Sumihiko! Exclamation marks are my soul! The descendant of Shinazugawa Sanemi, Shinazugawa Mihiro: I'm Shinazugawa Sanemi. He came looking for the two bratty boys. We are your legacy. We are your future. Look, this is a reflection of the happiness of a world without demons, and this is what you will have, too. So which brat came up with the idea of making us impersonate our ancestors? Is there a rule against it? And does anyone remember that we're just innocent cosplayers? Do we really have to make this plot even more complicated? *I wrote this blurb on a whim and now feel great. I haven't decided whether this will be a collection of light, scattered gags or a more serious story built around wild speculation. *An unconventional cosplay story, written for myself. It's also an unconventional group transmigration story, though I don't know what a typical one would even look like. *Although the protagonists have these identities, their goal isn't to bring couples together. There are no couples in this story; anything goes. Theme: The grandfather paradox doesn't apply to cosplayers. Right? Right...?
