Updates will be slow, as every chapter is very long atleast 3000 words per chapter. [Naruto × Demon Slayer Fanfiction.] Two years after defeating Muzan Kibutsuji, the Water Pillar Giyu Tomioka passed away peacefully. He expected to reunite with his family and comrades in the afterlife, but to his surprise, he woke up as a newborn baby in the ninja world, and not just any baby— but as Sasuke Uchiha's twin brother. With no enemies or goals left, Giyu grew up without the desire to become a ninja or engage in battles. He decided to dedicate his life to taking care of Itachi and Sasuke, finding solace in a peaceful existence. However, everything changed on his fifth birthday when a voice entered his mind, altering his destiny. 【After spending 1 hour in close proximity to Itachi, Flame Breathing proficiency +0.02%.】 【Once Flame Breathing reaches an intermediate level, the Flame Pillar Rengoku Kyōjurō can be resurrected.】 Determined to revive his fallen comrades, Giyu compelled himself to embark on a path of making friends. In short, this is the story of the pillars' resurrection in the ninja world and their new lives. ------ This is a fanfic translation from a Chinese novel. 我，宇智波义勇，没有被讨厌！ SUPPORT ME ON - https://www.patreon.com/Lazy_Panda
