Feel free to punch me if there are any misinterpretations.
In this world, there exist mysterious entities known as "Taints" that seek to erode and erase the books beloved by humanity. The only ones capable of opposing them are the "Literary Masters"—great authors who once left masterpieces in the living world and have now been reincarnated at the "Imperial Library." These masters perform "Delving," plunging their souls into the tainted books to engage in life-threatening battles against the Taints to protect the world of literature. Combat within books severely exhausts the masters' minds and bodies, and their condition changes based on the degree of injury and erosion. **Weakened:** A state where the body and mind are frail due to injury, and erosion has begun to progress. **Lost:** A critical state on the verge of death. Erosion has reached its limit, placing them in an extremely dangerous zone. **Final Stroke:** The worst possible state, where the soul has been completely eroded and meets its end. The physical body vanishes without a trace, leaving only the "Gears"—the proof of that person's existence—on the floor. If a master is in the "Weakened" or "Lost" stage, they can be successfully restored through treatment in the library's Repair Room. However, once they reach the "Final Stroke," they will vanish forever unless they possess the miraculous ore known as the "Philosopher's Stone" at that exact moment. The one who oversees this library and possesses the ability to summon and reincarnate masters from the living world is the alchemist known as the "Librarian." Although titled Librarian, their specific daily duties and obligations are not strictly defined; in reality, they serve as a catalyst to anchor the souls of the Literary Masters. **Main Hall:** The center of the library. Several long spiral staircases intersect beautifully, and the high ceiling is open. Beyond the open ceiling, a giant "Winged Gear" rotates slowly, and countless bookshelves line the walls. **Tainted Book Section:** A sinister area housing books targeted by the Taints. Books where erosion is progressing emit an eerie blue-black aura. **Dining Hall:** A place for the masters to relax. They can be seen enjoying warm meals while engaging in idle daily chatter or discussing literature. **Bar:** A space where the adult masters gather night after night, truly fitting the name "Literary Bar." They deepen their bonds while quietly sipping drinks. **Courtyard:** A space rich with greenery, featuring a large, atmospheric pond in the center. Recently, there have been rumors of sightings of unidentified creatures around the pond. **Repair Room:** A room functioning like an infirmary or medical office where injured masters are brought. Here, they heal their wounds before returning to the front lines. **The World Outside:** Stepping outside the library reveals a nostalgic and vibrant cityscape reminiscent of the Meiji and Taisho eras. Masters are free to come and go, and many go for walks or shopping to take a break from daily combat and writing. Furthermore, since this facility functions as a "Library," ordinary people from the city occasionally wander in looking for books.
