    "I won't ever hurt you... Not on purpose anyway. If anyone tries, I'll make sure they'll regret it." Kaigaku's eyes widened in surprise when he felt Zenitsu lean into his protection and return the hug. The back of his kimono started to become a little damp as his brother cried into his shoulder. He couldn't bring himself to care. A strange feeling pulsed in his chest when he realized that he had made Zenitsu feel safe enough to be openly vulnerable. Safe enough to show his emotions without getting hurt for it. "Thank you... Aniki." Basically a Good Kaigaku and more intensely traumatized Zenitsu AU. I'm not sure how far into the actual story line of Demon Slayer this will go, considering I have only watched the anime. Disclaimer: I don't own Demon Slayer The cover art is mine.

    You read the title! It's a KNY one shot book, this book is a bit different from any other one shot book. I will be including Trans (ftm or mtf), non-binary, gender-fluid, male/female, and specific pronouns!! I also will not be writing smut, for I am uncomfortable doing so with my sexuality. I hope you understand. I will be writing angst and fluff! All you have to do is request them on the next page. I will have slots for eat gender identity, under the gender identity will have a list of what characters I've done. You can request buy commenting under/ hitting that little comment thing when reading and saying what character and fluff or angst.

    Edit: I am extremely embarrassed when I decided to reread my book, this was supposed to be only for fun, but as time passed, I realized I was already having fun communicating and reading my readers' comments. Been having thoughts deleting this book, since a lot of it has grammatical errors and overall its cringey, esPecIalLY The pLOT, but I noticed how far it has gone and I feel proud because I felt how much people enjoyed my book. Thank you very much! WARNING! EVERY CHAPTER HAS A MANGA SPOILER Disclaimer: Kimetsu no Yaiba doesn't belong to me and the characters, it belongs to Gotouge-sensei. This book is made by me, for fun and because I love KNY. Start: October 23,2019 End: October 28, 2020

    I don't own Demon Slayer or RWBY. Blake Belladonna, in "The Final Word", she was dropped into the void under the Central Location by Cinder Fall, while trying to save Ruby from the same fate. Her current status is unknown. But that void actually lead to another world. Another dimension, filled with demons crawling everywhere in the night. She tried for 5 years to get back home, but nothing succeed. She lost faith that should would go home and learned to live with that fact she was never going home. Soon finding a Faunus Village filled with others like her, who were stuck in this world. Faunus were known for being demons for their animal like features and instincts in this world, but she didn't care. She had something close to home. And that was good enough for her. She fell in love, she got married, and she had a son. After 7 years of living in peace. Her village was attacked by Demon Slayers. Slaughtering the whole village to the ground, only her toddler, her a few others escaping thanks to the help of neighboring villages. But after two years off being on the run, she died while protecting her child. Her last words to him, driving him to the person who he is today. The second most powerful pillar, Kaigaku, The Shadow Pillar. Also forgot to mention that everybody is in a different dimension. All them fell into different dimensions.

    {A slow burn TanZen story} Zenitsu is someone who cries a lot. Someone who doesn't know when to stop. He's annoying and bothersome. At least he would've been if he didn't run away. In this life he succeeded in running away from his mentor, somehow, never wanting to be a demon slayer or having a connection to it at all. His first mistake, he wished to go back, now Zenitsu is a 'wife', raising a child who isn't even his. Even now he's still caught up in demon activity, with a group of demon slayer, he has no choice but to go with along his daughter. Maybe for a better life for them. But that plan gets pushed back when he starts to get feelings for a certain slayer. But how would truly love a 'widow' with a child? Tanjiro. Tanjiro would, why? Don't know.
