Song of Water and Flame: A Journey Through the Ninja World

Water and flame have always been natural enemies. Yet, the moment they transmigrated to the ninja world, Giyu Tomioka, the Water Hashira of the Demon Slayer Corps, and Kyojuro Rengoku, the Flame Hashira, became each other's only support. When the Breathing Styles used to slay demons clash with mysterious ninjutsu, and the fiery Rengoku meets the cool and composed Tomioka, they will carve out a new path across this unfamiliar land with their Nichirin swords, composing a battle song of ice and fire.
