Pirate Luffy: Is the Red-Haired Man's Severed Arm Sealed in the Straw Hat?

He bit off the Red-Haired man's arm from the start, and the straw hat became a seal suppressing demons!

Makino repeatedly warned him never to take off the hat. The whole village trembled in silence, and even Navy captains were terrified at the mere mention of it.

To expose this hypocritical facade, Luffy sailed into the open sea in a ramshackle wooden boat, crushing every scheme against him with the most straightforward force.

When bullies trained giant nets and heavy cannons on him, hoping to capture him alive for a reward, Luffy stretched his body a hundred yards, bounced back the cannon fire, and punched an entire battleship down to the ocean floor to feed the fish!

"Only when a Navy admiral opened the classified files did he discover that beneath that seemingly worn-out straw hat lay a heaven-defying taboo powerful enough to overturn Mary Geoise!"
