Demon Slayer: Observer's Diary

Demon Slayer: Observer's Diary Lin Mo, an intern observer at the Space-Time Management Bureau, was accidentally bound to the observer system and was thrown into the world of Demon Slayer: Kimetsu no Yaiba. His task is to record key plot points without changing any main plot developments. The system gave him special abilities, but also set many restrictions: he could not touch the Nichirin Sword, he could not talk to the main character for more than three sentences, and he could not save people who were destined to die. On the streets of Asakusa, he witnessed the first encounter between Tanjiro and Muzan; at Spider Mountain in Nada, he recorded the death data of the fifth string; in the decisive battle of Mugen City, he was forced to witness the sacrifice of his companions. Each mission brings him closer to the truth, but it also makes him deeply involved in the conspiracy of the system - those seemingly simple observation missions are actually extracting the original energy of the world. When the system finally requires him to end Tanjiro's life with his own hands, Lin Mo must make a choice: complete the mission and return to reality, or break the rules and save the world? Hidden behind the observation log is an epic story about courage, sacrifice and redemption. This novel and its characters are purely fictitious.
