One Piece: Rinnegan Is My Golden Finger.

Due to running too fast, by the time Law and Ace reached Chiga, Law was already panting heavily, hands on his knees.

Compared to the out-of-breath Law, Ace showed no signs of fatigue.

Ace was Roger's son, after all—healthy since childhood and frequently "trained" by Garp. Now, under Garp's direct one-on-one tutelage, his strength was improving rapidly.

Don't let his young age fool you; his physical fitness already surpassed that of many Marine soldiers.

Law, on the other hand, had only recently recovered from his illness. His current life was far more comfortable than it had been in the original timeline, allowing him to focus more on studying medicine than combat.

As the two boys arrived in front of Chiga, both of them, without any prior discussion, were drawn to the horn on Chiga's forehead.

Ace blurted out, "Brother Chiga, why do you have a horn on your head like that idiot Yamato!?"

Yamato's face immediately darkened. She flashed over to Ace and smacked him hard on the head.

Ace yelped, clutching the new bump on his head as he glared at Yamato. "You always pick on me! Just wait—I'll grow taller and stronger than you one day!"

Hearing this, Chiga shook his head, amused. Taller and stronger? Forget it. Even when you grow up, you'll still look tiny next to her.

Yamato scoffed. "Hmph, you think I'm scared of a little kid like you? Taller and stronger? Keep dreaming! I'm learning a special training method from Master. You'll never beat me!"

"Nani!? Brother Chiga, is that true?"

Chiga didn't answer Ace. Instead, he gave Yamato a matching bump on the head, silencing her immediately.

After calming the two down, Chiga smiled and rubbed their heads. "What are you two up to?"

Ace puffed his chest. "I learned Soru from Grandpa today! Brother Chiga, wanna see!?"

"Oh?"

Chiga raised an eyebrow, skeptical.

While Ace had impressive talent, Soru required immense physical strength and control. It was hard to believe someone so young could pull it off.

Spurred by the disbelief, Ace immediately sprang into action.

He took a deep breath, then began stomping his feet rapidly on the ground. It looked dramatic—if nothing else.

Chiga nodded inwardly. The Roger bloodline truly held potential.

Ace whispered seriously, "Soru!"

Swish!

He vanished from sight. A beat later, he was plastered against a large tree, limbs splayed. Slowly, he slid down to the ground.

Kalifa and the other two women stifled their laughter behind their hands, while Law facepalmed in embarrassment.

Ace sat up, groaning, holding his head. "I did it earlier today… Why did I mess up now!?"

Chiga chuckled and let the boy stew in his failure. Once he confirmed Ace was fine, he turned to Law.

Law felt his gaze and immediately looked down, uneasy.

Even though Ace failed, at least he dared to try. Law doubted he could even attempt it without humiliating himself.

Chiga was familiar with Law's usual reaction and asked gently, "Law, Ace just showed me what he's been learning in the Marines. What about you? Got anything to show me?"

Law stiffened. He thought Chiga was referring to combat training, which he had little interest in. He had focused most of his efforts on studying medicine.

Feeling embarrassed to be asked like that, Law didn't want to disappoint his idol.

Seeing Law hesitate, Chiga remained patient. "What's wrong? Having trouble with your studies lately? It's alright—medicine is a complex subject, after all."

"Huh? Chiga-San, you're talking about medicine?"

"Of course. What else?"

"No, no—I thought you meant combat training! I wasn't expecting that!"

Realizing the question was about his medical studies, Law's eyes lit up. He spoke earnestly, "Chiga-san, I've recently been researching the anatomical differences between male and female bodies—"

Kalifa and Ain's faces flushed red at that, while Yamato tilted her head, clearly confused.

Chiga coughed lightly. He interrupted Law before the explanation went too far and retrieved the syringe-shaped Horu Horu no Mi from his Door-Door Dimension, placing it in Law's hands.

Law stared at the Devil Fruit, then up at Chiga, visibly confused.

Chiga smiled, rubbing his head. "You've been working hard. This is a reward. It's the Horu Horu no Mi. With it, your medical skills will reach new heights."

"This… is for me?"

Law's eyes widened. He knew how precious Devil Fruits were. Even the most useless ability could fetch hundreds of millions of Berries on the market.

For Chiga to give him one so casually…

Law trembled, tears welling in his eyes. He had no idea how to repay such kindness.

Chiga noticed the boy's emotional reaction. He crouched down and said warmly, "Don't feel pressured. This fruit isn't just for you—it's for the Navy as a whole. I believe that with this power, you'll save countless lives in the future."

Moved by Chiga's words, Law clutched the Horu Horu no Mi, steeled himself, and took a bite.

To Chiga's horror, Law stuffed the entire fruit into his mouth.

Just imagining the soul-wrenching taste of that fruit made Chiga shudder. He'd only eaten a small piece of one and nearly passed out from the flavor.

Sure enough, Law immediately began gagging. He tried to spit it out, but Chiga quickly covered his mouth and forced him to swallow it down.

After several seconds of dry heaving, Law collapsed to the ground, tears in his eyes. Eventually, he looked up at Chiga, face pale, and croaked out, "Chiga-San… is this really something humans are supposed to eat?"
