πI recommend the following Doujin novels to you to see if they meet your needs: "Origins from One Piece","Rebirth in the 2D World","Control Time from Naruto","I Don't Want to Be a Hero","Death's Strongest Ninja","The Raging Python of the Myriad Worlds Devouring and Evolving","One Piece: I loaded the game panel, the shadow of the fourth generation of the wooden leaf, the sword hero of the demon tail, the throne from Naruto, the hunter of interest, One Piece: Sword of the Heavenly Chasm, Naruto: Ghost Sword Susa, and I picked up corpses in anime. These novels were all Doujin novels of Naruto, Shifter, One Piece, and Death. Some of the novels involved multiple worlds, such as Rebirth in the 2D World and Control Time from Naruto, so they could be read according to their preferences. Some of the novels might be in the midst of being serialised. It was recommended that he check out their updates in the book friend group. I hope you like my recommendation, Mwah ~π
