This should be the only case scenario if this author wasnt a fraud:-
In a chilling display of authority, Imu uses the "Domi Reversi" ability on Sanji, triggering an instantaneous metamorphosis. Sanji’s hair shifts to a void-like black and his eyes lose their spark as he becomes Stealth Black—not through a suit, but as a cold, biological evolution. Imu watches with dark curiosity, pondering if Sanji can finally handle "That Power" now that he is unburdened by a heart. Sanji enters a mindless rampage, moving with such localized velocity that he creates a vacuum, collapsing the surrounding area. Zoro is forced to intercept him to fulfill his duty, but he quickly realizes this is not the rival he knows. Because the "Domi Reversi" has allowed Stealth Black to fully take over, the mental barriers restraining Sanji’s latent Haki shatter; Sanji begins leaking thick, black streaks of Advanced Conqueror’s Haki (ACoC). Zoro finds himself unable to overpower Sanji, as the combination of Germa's physical hax and the raw, unrestrained King’s Haki creates an ironclad defense that cuts through Zoro's own techniques.
When Usopp attempts a desperate distraction, Sanji’s predatory focus shifts toward Nami and the others. Imu seizes the moment, commanding the hollowed-out cook to erase the Straw Hats. Just as Sanji is about to strike Nami, we see a flashback to a conversation with Scopper Gaban. Gaban explains that Sanji is a house divided: two distinct personalities, Stealth Black and Black Leg, exist within him. He reveals that while the Stealth Black persona is a born conqueror, the Black Leg persona is not—and that to truly wield the Color of the Supreme King as himself, Sanji must unite these two warring halves. Gaban speaks of the "Will of Romance"—the primordial force the Ancient Kingdom used to physically alter the world through emotion. This is the same power that birthed Devil Fruits and hybrid species. He notes that most humans explode if they consume two fruits because they lack the internal harmony to host two conflicting souls; only the "Power of Love" allows a being to bridge that chaos and unite their fragmented selves.
Inside the confines of his mind, Sanji faces the manifestation of Stealth Black. The ego-less soldier mocks Sanji’s "Black Leg" persona as a weakness, gloating that only the cold, heartless version of Sanji is capable of wielding the King's Haki. Instead of retreating, Sanji uses the Power of Love to dominate the persona, refusing to let the conqueror be separate from the man. He forces the Germa shadow to kneel, melding their strengths into one singular, sovereign will. In the physical world, black tendrils of lightning burst forth as Sanji’s leg stops inches from Nami’s face. His voice returns, steady and fierce: "Even if I die, I will never kick a woman."
Imu is visibly shaken, a fractured memory of Nefertari Lily flashing through their mind. "NOT ANOTHER ONE!" Imu screams, recognizing the same rebellious, unified spark. Sanji doesn't hesitate; he turns his fury toward Sommers, who is lunging at Robin. With his two halves finally acting as one, Sanji unleashes a surge of his own perfected ACoC, vaporizing Sommers' vines and revealing a new, terrifying flame mode: CHARON JAMBE: MOUTON STRIKE, one-shotting the enemy in a display of absolute peak power.
