Comprehensive Manga: Starting from Demon Slayer, Killing the Powerful Ones in the Heavens

After the battle with Saba, the soul of Miyamoto Musashi, the strongest swordsman, should have continued to wander in the distant past. But when he opened his eyes again, Miyamoto Musashi was surprised to find that he had entered a whole new world! There is no need to think about why you are here, and the burning desire to fight in your body no longer needs to be suppressed! The first-class Ertian who has not yet evolved completely needs to see more powerful people! Huh? Man-eating ghosts who are afraid of the sun but cannot be killed, tall giants born from lightning and thunder, undead demons who are the first to create weapons, an urban world full of monsters... Scarlet ghoul ghosts behind them, and double-faced monsters that are also unparalleled in killing? I, Musashi, can kill him!
