Onepiece: I'm Gojo Satoru

The three of them made their way to the Naval Academy's training grounds. Naturally, Garp, who never missed any excitement, tagged along, eager to witness the showdown.

To Satoru's surprise, the normally bustling training ground was empty. Not a single student was in sight—a deliberate move by Zefa to ensure they had the space to go all out.

"First things first, don't use that defensive ability of yours," Zefa said sternly. "If you do, this fight won't even be fair."

"Don't worry, Master," Satoru replied with a smirk. "I'll make sure you admit defeat."

"Oh? Bold words from a boy."

Without another word, Zefa launched himself forward, closing the distance in an instant. His fist, imbued with powerful Armament Haki, shot toward Satoru with terrifying speed.

"Zefa's not holding back at all," Garp thought to himself, a grin tugging at his lips as he watched from the sidelines.

The impact of Zefa's punch sent shockwaves rippling through the ground, creating a massive crater and sending up a thick cloud of dust. The sheer force of the attack was enough to alarm the entire Navy Headquarters, with many fearing they were under attack.

Inside the main building, Fleet Admiral Sengoku frowned. "What's going on now?" He quickly activated his Observation Haki and sighed in relief when he realized it was just Zefa and Satoru.

"Those two are always causing trouble," Sengoku muttered.

Vice Admiral Tsuru, standing nearby, added, "I would've expected this kind of chaos from Garp, not Zefa."

Meanwhile, the three admirals—Aokiji, Kizaru, and Akainu—also turned their attention toward the commotion. They all knew Zefa's strength well and were curious to see how Satoru would measure up.

Back at the training grounds, Zefa glanced at Satoru, who had evaded the punch with ease.

"Running away already, boy? Fight me head-on if you've got the guts!" Zefa taunted.

"Speed is part of my strength, Master," Satoru replied with a confident grin.

"Didn't you say you'd make me admit defeat? Don't disappoint me!" Zefa shot back, using the provocation to draw Satoru into a direct clash.

"Alright, Master," Satoru said, his smirk widening. "Just don't cry later."

"If you can make me cry, I'll call you 'Dad.'"

Hearing this, Garp burst into laughter. "If Zefa calls you 'Dad,' does that make me the grandpa?"

"KNOCK IT OFF, GARP!" Zefa roared, his glare silencing his old friend.

At that moment, Satoru's voice rang out. "Master, focus—I'm coming."

Both fighters moved simultaneously, their fists colliding mid-air in a flurry of afterimages. The sheer impact of their clash created a shockwave that echoed across the training grounds.

"I didn't expect your Armament Haki to be this strong," Zefa admitted, his tone tinged with pride.

"There's nothing I can't do if I set my mind to it, Master," Satoru replied, his confidence unwavering.

"But you're still young," Zefa said, channeling his full strength into his next move. His powerful punch sent Satoru flying across the training ground.

"Guess I still don't have the upper hand in raw strength," Satoru thought as he steadied himself.

Zefa leaped into the air, aiming to finish the fight with a devastating kick. "No mercy at all, huh, Master?" Satoru muttered before activating his ability.

"Reversal Surge!"

A burst of repulsive energy erupted beneath Zefa, sending him hurtling backward. He crashed into the ground with a thunderous impact, leaving a sizable crater in his wake.

Garp, watching from the sidelines, was wide-eyed. "What the hell was that?!"

"Master," Satoru said with a grin, "don't forget—I have more than just defensive abilities."

Zefa knelt in the rubble, his expression grim as he realized what had happened. Satoru's use of repulsion was a reminder of the dangerous versatility of his powers.

"Looks like you've mastered it," Zefa said, standing up and brushing off the dust. "But don't think you've won yet."

"Why not admit defeat, Master?" Satoru teased.

"Admit defeat? Not in this lifetime!" Zefa roared, his aura erupting with a ferocity that took Satoru by surprise.

The usually composed Zefa now exuded a menacing ghostly energy—an unexpected transformation for someone once known as the "Non-Killing Admiral."

Satoru narrowed his eyes. "This... This is new."

"Get ready, boy," Zefa growled. "The real fight starts now."
