I don't know what the " Demon Slayer Order 18 Final Version Inheritance Will OP " is. Can you provide more context so that I can better answer your question?
The Swordsmith Village Arc in Demon Slayer is really exciting. It focuses on Tanjiro and his friends protecting the swordsmith village. There are new and powerful demons that attack. Tanjiro has to face these threats while also dealing with his own growth as a demon slayer. The arc also shows the importance of the swordsmiths and their unique skills in making the swords that are crucial for the demon slayers.
After the Swordsmith Village Arc, you should start at the chapter that directly follows it. Sometimes, you can check the manga's official website or forums for specific chapter numbers and guidance.
There are a few novels that I can recommend to you. They are all stories about being reborn as a Demon Slayer. The first was "Rebirth of the Sea of Laws, I Slay Demons in the Human World" and "Rebirth of Slaying Demons, I Actually Became a Demon Venerable?" They all focused on slaying demons and told the story of the protagonist becoming a demon slayer after his rebirth. In addition, there was also "Xu Xian's Demon-slaying Daily Life (Demonic Meow)" and "Black Moonlight of the Rebirth of the Demon Lord," which also involved the demon-slaying plot. These novels all have different styles and storylines. You can choose to read them according to your preferences.
Definitely! Demon Slayer started as a manga. It's known for its compelling plot and well-developed characters. The manga provides the foundation for the success of the anime adaptation.
