R's Journey Through the Moving Castle

If swallowing a screw lets you build an anti-tank cannon with your bare hands, then can you also drink a whole bottle of gasoline? And what would happen if you ate a vampire? What? You can even take magic head-on with your teeth clenched! An ordinary shut-in boy, known by the codename R, has always survived on manga and novels for spiritual sustenance. Now he has somehow been saddled with the mission of saving the world. How will someone with Eat-Man's ability develop his powers? The road ahead is long, but the manga journey his mental strength will set in motion is truly something to look forward to: Kenji, Sakamoto Days, Queen of Gunfire, Black Lagoon, Hellsing, Berserk, Dorohedoro, Hunter x Hunter, Fullmetal Alchemist, Toriko, and more. Fists and feet, blades and swords, or all manner of bizarre abilities: are these powers the world's roar, or its mercy?
