Dashing! The Righteous O-Soba Mask!

Sanji triggers his raid suit can and becomes the sleek, technologically enhanced Stealth Black, though he rejects the Germa 66 name and dubs himself Soba Mask instead. He opens the fight by driving a kick into Page One's throat. When Page One swipes with a claw, Sanji's cape hardens into a shield to block it, and the suit's standout trick, full invisibility, lets him strike at blinding speed until Page One drops and shifts into his hybrid form.

In Udon, Luffy nags Kid for more dumplings inside their cell, but Kid pays him no mind. At the mansion, Orochi's opulent party rolls on while Komurasaki plays him a tune on her shamisen. Robin, having slipped away from the festivities, searches a room for the Poneglyph but is swiftly discovered by the Orochi Oniwabanshu, the shogun's personal squad of ninjas, whose leader Fukurokuju offers her a chance to account for herself. As Soba Mask, Sanji keeps trading blows with Page One; at one point Page One hoists him and hurls him into houses, and though unhurt, Sanji is determined not to wreck the buildings. After landing a single heavy blow, he bolts into the sky, with Usopp, Law, and Franky also fleeing to keep their identities hidden.

The episode ends with the "To Be Continued" text appearing as Sanji slowly turns invisible. Added scenes include Page One swinging his tail at Sanji before the suit goes on, and a young Law reading Sora, Warrior of the Sea with his little sister, where all the fictional Germa 66 members appear, Stealth Black shown in a yellow suit rather than black. Sanji strikes a dramatic pose when introducing himself, and in Udon, Luffy wakes from hunger to pester Kid. The Page One fight is lengthened, with Sanji taking longer to introduce himself and using the cape to block. Law explains more about raid suits than in the manga. Unlike the manga, the anime shows Sanji fleeing after a strong kick without leaving Page One incapacitated. Many Orochi Oniwabanshu members debut here, including Fukurokuju, alongside Sanji's Ryusei Osoba Kick.
