Episode 1004

"An Inherited Technique - Unleashing Oden's Secret Swordplay" is the 1004th episode of the One Piece anime.

Short Summary
Bao Huang spies on Yamato. Meanwhile, the Nine Red Scabbards inherit Oden's Two Sword Style, and slash Kaidou in his honor.

Long Summary
As Queen continues firing Excite Bullets into the crowd, King orders Bao Huang to locate Kozuki Momonosuke. Momonosuke is in the hallways, still being chased by Shinobu. Although Momonosuke and Shinobu attempt to hide from them by hiding on the ceiling, an explosion causes them to fall and be seen by Yamato. They run away from Yamato just as they are spotted by a black cat with Bao Huang's mask. With this, Black Maria continues her song hinting at a reunion. The song ends with Maria breaking the string of her shamisen.

The Nine Red Scabbards work together to battle Kaidou. Raizo and Denjiro strike Kaidou's underbelly, Kin'emon climbs onto his body and pierces his head, and Inuarashi and Nekomamushi strike him with Electro. Kaidou is still unharmed, flinging them to the ground before blasting them with fire. Still, just like Oden twenty years ago, the samurai rise in the flames. They remember when Oden offered to teach his retainers Oden Two Sword Style, but they all refused. So, using their individual fighting styles, they each take turns attacking Kaidou, each managing to pierce his body.

Kaidou is still unharmed. So, the Nine Red Scabbards decide to mimic Oden's Two Sword Style in honor of Oden. Kaidou shoots several fireballs at them, but they evade them. Kin'emon clashes against Kaidou's Bolo Breath, then they all perform a move, "Togen Totsuka," slashing Kaidou's underbelly just like Oden did twenty years ago.

Anime Notes

 * This is the last regular episode to use DREAMIN' ON as the opening theme.
 * The anime adds the following:
 * Black Maria still playing her song.
 * One of the strings from Black Maria's shamisen is cut off.
 * The anime extends the following:
 * Yamato still chasing after Shinobu and Momonosuke.
 * The flashback of Oden offering the Scabbards the art of his Oden Nitoryu fighting style.
 * The scene of Oden (with Toki) wondering why the Scabbards didn't want to learn his style is omitted.
 * The Scabbards' battle against Kaidou.
 * This episode's "To Be Continued" end screen has sakura petals twirling in front of the text. This is because of Oden passing away after his battle with Kaidou.
