“The monsters in this world… you can’t punch them to death?”
Luffy stared at the demon that had been smashed apart by his rubber fist, only to regenerate in an instant, and fell into deep thought.
“You need this special sword. You have to cut off their heads.”
Tanjiro handed him a Nichirin Blade, but the moment Luffy took hold of it
Flames erupted along the blade, and his rubber body resonated with Flame Breathing!
Zoro: “Swordsmanship in this world… is called Breathing Style? Interesting!”
(Three-Sword Style × Wind Breathing = Armament Haki Nichirin Blade. Upper Rank Demon: Where did my regeneration go?!)
Sanji: “Protecting ladies is my duty. Miss Nezuko, you can relax!”
(Kicks × Flame Breathing + demon-resistant medicine = the perfect all-round heartthrob)
When the pirates’ Haki meets the Demon Slayer Corps’ Breathing Style,
when the space-time BOSS Yeluo tries to resurrect Muzan with the fragments,
Luffy entrusts his straw hat to Tanjiro:
“This is proof of freedom. Next time we meet, you’d better be even stronger!”
