Onmyoji of the Grand Line

"Seimei, this time our opponents aren't ordinary pirates; they possess the power of Devil Fruits. We need to be careful," Luffy warned alertly.

Seimei nodded, gazing intently at the Devil Fruit user with determination and confidence.

"I understand, Luffy. We will find their weaknesses and give them the retaliatory blow they deserve." Seimei took a deep breath, a burning fighting spirit surging within him.

The battle began, and the Devil Fruit user unleashed his power, manipulating destructive elements. Seimei swiftly dodged enemy attacks, nimbly weaving through the battlefield, employing the Yin-Yang technique "Agile Body" to transform himself into an elusive, elusive figure.

Chapter 454: The Light of Yin and Yang!

"You guys, don't think you can easily defeat us just because you have Devil Fruits!" Seimei shouted, while using the Onmyoji skill "Soul Seal" to release powerful spiritual energy.

Spiritual energy surged like a tide, gradually weakening the Devil Fruit user's power. Seimei's goal was to weaken the opponent's power and reduce their threat level.

"You bastard, you actually have such methods!" the user of the "Seven-Eight-Seven" Demon Fruit exclaimed in astonishment, as he felt the weakening effect on his spiritual power.

Seimei did not stop his attack; he stared intently at the Devil Fruit user, a burning desire for victory igniting in his heart.

"I will not allow you to continue to act recklessly!" Seimei shouted resolutely, his whole body radiating a strong yin-yang light.

The Devil Fruit user sensed the energy fluctuations emanating from Seimei, and his expression turned serious. He understood that Seimei was a formidable opponent and that he had to eliminate him as soon as possible.

The Devil Fruit user unleashed even greater power, manipulating destructive elements to attack Seimei. However, Seimei, relying on the agile evasion of his Onmyojutsu "Agile Body," maintained control of the battlefield.

"No matter how powerful you are, I will not back down!" Seimei shouted through gritted teeth.

Seimei decided to make one last desperate attempt. He concentrated all his Yin and Yang power, condensing it into a massive energy sphere. This was his strongest attack, the pinnacle of his Onmyoji skill "Soul Seal."

"Soul seal, unleash your power!" Seimei roared, raising his hands high, and the energy ball instantly flew towards the Devil Fruit user.

The Devil Fruit user's eyes widened as he tried to dodge the fatal blow, but it was too late. The energy ball erupted with a dazzling light, enveloping the Devil Fruit user.

The incredibly powerful energy instantly shattered the Devil Fruit user's defenses, engulfing him in scorching light and unleashing a deafening scream.

Finally, the energy ball dissipated, and the Devil Fruit user collapsed helplessly to the ground, his power suppressed by Seimei's "Soul Seal".

Seimei stood on the battlefield, his chest heaving, radiating a powerful aura. He had achieved victory and successfully protected his comrades.

Luffy walked up to Seimei and said with admiration, "Seimei, you're amazing! Your Yin-Yang techniques are truly incredible!"

Seimei smiled broadly and nodded to Luffy in gratitude.

Seimei and Sakuragi stood facing each other, an atmosphere of battle emanating from them. Sakuragi was a ninja proficient in ninjutsu, possessing swift movements and superb skills.

"Seimei, your Yin-Yang techniques are indeed powerful, but can you withstand ninjutsu?" Sakata-maru said with a sneer.

Seimei showed a determined smile in the face of Sakata-maru's challenge.

"Come on, let me see just how powerful your ninjutsu really is!" Seimei responded challengingly.

The battle began. Suddenly, Sakata-maru vanished from his spot, leaving only a 0.5-second afterimage. He circled Seimei at incredible speed, trying to find an opportunity to attack.

Seimei calmed his mind and body, and used the Yin-Yang technique "Phantom Fusion". His body flickered and changed unpredictably like a phantom, making it difficult for Sakata Maru to grasp him.

"Your movements are indeed swift, but with my illusionary fusion, your attacks cannot reach me!" Seimei said confidently.

Chapter 455: The Iron Fist!

Sakata-maru roared angrily, deciding to use an even more powerful ninjutsu to attack Seimei.

He transformed into a streak of sword light, instantly appearing beside Seimei, attempting to launch a fatal blow. However, Seimei reacted swiftly, using the keen senses granted by Onmyojutsu to evade Sakata-maru's attack.

“Your attack speed is fast, but it is not enough to pose a threat to my Yin-Yang Arts!” Seimei said calmly.

Seimei gathered all the Yin and Yang power in his body and used the highest level of Yin-Yang technique, "Phantom Fusion." His figure became illusory, as if he had merged with the phantom.

Sakata Maru was stunned. He sensed the increase in Seimei's power and the impending pressure.

Seimei swiftly approached Sakata Maru, his body emitting countless rays of light amidst the phantom. With a low roar, Seimei's attacks were swift and precise, striking Sakata Maru repeatedly like a phantom.

Sakata Maru tried his best to dodge, but Seimei's attacks were relentless and relentlessly pursued him.

In the end, Seimei's fist struck Sakata Maru directly, sending him flying and crashing to the ground in a sorry state.

"Your ninjutsu may be unique, but it cannot stand against my Yin-Yang Technique!" Seimei stood in front of Sakata Maru, his voice filled with the confidence of victory.

Sakata Maru struggled to his feet and glared at Seimei with a venomous look.

"Seimei, your Onmyojutsu is indeed powerful, and I admit my defeat. But don't be too smug. This is just a battle, and we will meet again!" Sakata-maru said through gritted teeth, then quickly disappeared into the shadows.

Seimei watched Sakata Maru's departing figure and smiled gently.

Seimei and Roronoa Perel stood on the island, their eyes meeting, their fighting spirit palpable.

"Seimei, are you here to challenge me? Then you'd better watch out, my steel power is unmatched!" Perel said mockingly.

Seimei's gaze was firm, and the Yin and Yang power on his body gradually merged into the surrounding metallic elements.

“Roronoa Perel, I will not be intimidated by your steel power. I will fuse my Yin and Yang power with metal to unleash even greater strength!” Seimei replied without flinching.

Seimei quickly gathered his strength, concentrating Yin and Yang power in his hands, causing metallic elements to condense into a dazzling light around him. He used the Yin-Yang technique "Metal-Metal Combination" to fuse his Yin-Yang power with the surrounding metallic elements.

Perel was startled by Seimei's actions; he sensed the powerful energy surging within Seimei.

“What kind of power is this? Impossible!” Perel muttered in shock.

Seimei's fist combined the hardness of metal with the heat of Yin and Yang, unleashing the Onmyoji skill "Iron Fist".

He swiftly launched an attack on Perel, his 787 fist flashing with metallic light, striking Perel like a bolt of lightning.

Perel struggled to resist, his body was shaken and he was forced to retreat, but he still gritted his teeth and persevered.

"Your strength is formidable, but my steel body will not fall easily!" Perel roared, his entire body surging with steel, forming an indestructible defensive wall.

Seimei did not back down; he continued to unleash his "Iron Fist," each punch imbued with the power of steel.

His fists clashed repeatedly with Perel's steel defenses, sparking dazzling flashes. Seimei's power gradually surpassed Perel's resistance.

Chapter 456: Sunlight Purification!

"I will not be defeated by you! My Yin and Yang power will conquer all!" Seimei roared, his whole body radiating a dazzling light.

The sound of fists clashing against steel echoed across the island, the scene exceptionally intense. Each of Seimei's punches carried a blazing yin-yang energy, attempting to penetrate Perel's formidable defense.

"You think your strength can defeat my steel? Ridiculous!" Perel roared, his body hardening even more, the steel-like texture permeating every inch of his skin.

Seimei's fists pounded against Perel's defensive wall like a storm, sparks flying everywhere.

"No matter how strong the steel is, it cannot stop my Yin-Yang power!" Seimei shouted through gritted teeth, his body radiating intense energy.

Perel's defensive wall began to crack, and he sensed the threat from Seimei. He gritted his teeth, his entire body surging with steel, trying to withstand Seimei's attack.

However, Seimei was not afraid. He gathered all his strength and swung his right fist like a bolt of lightning towards Perel.

"Iron Fist, Break!" Seimei shouted, his fist piercing through Perel's defensive wall and striking him directly in the chest.

Perel was sent flying backward in agony, his body slamming into a distant rock and kicking up a cloud of dust.

“Impossible…” Perel muttered to himself with difficulty, his once confident expression turning bewildered.

Seimei stood still, sweat dripping from his forehead, but the determination in his eyes did not diminish in the slightest.

"My Yin-Yang power can overcome everything, including your steel!" Seimei said firmly.

Perel slowly stood up, his eyes shining with admiration.

"Your strength far exceeds my expectations, Seimei. I admire your courage and perseverance. From now on, you will be a worthy opponent."

Seimei smiled and nodded, showing his respect for Perel.

"Thank you for your praise, Perel. You are also a remarkable warrior. I hope we will have the opportunity to spar again in the future."

The two shook hands, forging a deep bond of camaraderie. Despite the fierce battles they had fought together, they respected each other's strength and courage.

Seimei and Boa Hancock stood facing each other on the warship. Hancock was alluring and beautiful, her beauty possessing a deadly allure.

"Seimei, are you here to challenge me too? It seems you don't know the power of my Devil Fruit, which will be your fatal mistake," Hancock said with a charming smile.

Seimei was alert; he knew he had to stay clear-headed, or Hancock's Devil Fruit ability would render him unable to fight.

"Hancock, your beauty is undoubtedly a fatal temptation, but I will not be seduced. I will use my Yin-Yang techniques to defeat your Devil Fruit," Seimei replied firmly.

Seimei quickly gathered his strength, his hands emitting a faint light. He used the Yin-Yang technique "Enchanting Illusion" to maintain his clear mind and resist the temptation of Hancock's beauty.

A hint of surprise flashed in Hancock's eyes. She tried to unleash the effects of the Devil Fruit, but Seimei's Phantom Illusion Technique effectively neutralized her influence.

"That's impossible! My beauty should be enough to make any man fall for me!" Hancock roared angrily.

Seimei was not afraid. His whole body radiated a dazzling light as he used the Onmyoji skill "Sunlight Purification".

Chapter 457: The Power of the Bright Soul!

A bright ray of sunlight emanated from Seimei, filled with the power of justice and purity. This sunlight fell upon Hancock, quickly dispelling the effects of her Devil Fruit.
