Chapter Summaries

Yota learned that Konoha was forcing fourth-year Ninja Academy students to graduate early because the war had worsened, leaving him at risk of being sent to the front.

Yota arrived in a snowy world and identified it as Drum Island in the One Piece World. He headed toward smoke to find people and learn the timeline, but a huge carnivorous rabbit attacked him.

After defeating two Lapahns with Exploding Tags, Yota reached a town in Drum Kingdom and joined its largest clinic as an apprentice. He hoped to learn the Pirate World's medical techniques before seeking out Dr. Kureha.

• Yota defeated the two Lapahns with Exploding Tags, then treated their wounds and had them guide him to a town.
• Yota let the Lapahns go at the town's outskirts and marveled at how quickly their injuries healed.
• Yota found that the town still had several clinics and concluded the Munch-Munch Fruit user had not yet taken the throne.
• Yota asked to become an apprentice at the largest clinic, and a nurse overruled the butcher-like doctor and accepted him.

After months of working at Doctor Jack’s clinic, Yota learned that Wapol had not yet obtained the Munch-Munch Fruit and suspected it was still in Drum Kingdom’s royal treasury. He took leave and traveled to the capital, hoping to secure the fruit before Wapol could claim it.

• Yota impressed Doctor Jack with his medical knowledge and practical skills while training at the clinic.
• Yota overheard locals discuss the ailing King, Wapol, and the exiled First Prince, then concluded Wapol probably had not eaten a Devil Fruit yet.
• Yota realized the Munch-Munch Fruit could greatly improve his prospects and feared it might soon pass to Wapol.
• Yota asked Doctor Jack for several days of leave, took a map, and reached Drum Island’s capital by the end of the morning.

Yota infiltrated Drum Kingdom’s castle to learn where its treasury and Devil Fruit were kept. After the Old King died from the effects of Yota’s hypnotic medicine, Yota disguised himself as the king and headed for the treasury.

• Yota climbed into the castle and evaded its guards and servants as he made his way to the master bedroom.

• Yota woke the guards, berated them for sleeping on duty, and led them toward the treasury.

• Yota entered the treasury under the King's identity and took the Munch-Munch Fruit, more than a billion Beli, gold, a Grade Sword, and an Observation Haki training manual.

• Yota examined the Observation Haki manual and learned it taught a doctor's techniques for sensing details inside the human body.
• Yota questioned whether he could awaken Observation Haki despite not being from the Pirate World.

Yota discovered that the Munch-Munch Fruit had transformed his physique, allowing him to grow stronger rapidly through training and absorb far more nutrients from food. When he returned to the clinic, he learned that King Wapol’s law targeting doctors was forcing Jack and Ruth to leave Drum Kingdom, but Yota insisted they should wait because events would soon change.

• Jack worried that the exiled First Prince might become king and kill people with his indiscriminate Mycelial Poison Gas.

After learning medicine and training in Drum Kingdom for five years, Yota had become a skilled doctor and developed the Munch-Munch Fruit’s body-modification potential.

• Yota mastered Jack’s medical skills, traveled around Drum Kingdom practicing medicine, and continued training while waiting for his dimensional travel energy to accumulate.

• Yota forced Chopper to swallow his awful-tasting Soldier Pills, and Chopper complained before responding bashfully to Yota’s praise of his fur.
• Yota reflected that he could use the Munch-Munch Fruit and his medical expertise to imitate the physical potential of people like Kaido or Charlotte Linlin, though he would first have to survive analyzing them.

Yota discussed his plans to set sail with Chopper before a pirate ship approached the shore. Fire Fist Ace arrived carrying his sick first mate, Deuce, and explained that the Spade Pirates had come seeking treatment.

• Ace introduced Deuce as the Spade Pirates' first mate and said they had come to treat his illness.
• Yota asked whether the Spade Pirates had a ship's doctor, and Ace revealed that Deuce was their doctor despite being only a medical student.

• Yota accepted, surprising Ace when he realized Yota had agreed before he finished his pitch.

Yota realized the dimensional travel system gained energy when he participated in the story, and considered returning to the Naruto World to collect ninjutsu. A Marine ship caught up with the Spade Pirates, whose crew teased Ace about his persistent pursuer.

• Yota explained that his Munch-Munch Fruit gave him a second set of taste receptors while he ate the ship cook’s unpleasant food.
• Yota concluded that plot involvement had replenished his dimensional travel energy enough for two trips to new worlds or a round trip between the Naruto World and the Pirate World.
• Yota decided not to return to the Naruto World while aboard the moving pirate ship, since he might reappear in the ocean.
• The lookout spotted a Marine ship pursuing the Spade Pirates, and Yota used his modified eagle eyes to examine it.
• The Marines fired at the Spade Pirates, but their cannonballs mostly missed, and Ace easily blocked the shots that hit.

Yota watched Ace fend off Isuzu and learned that a Vice Admiral would soon pursue the Spade Pirates. After the crew landed on Jungle Island, Yota planned to travel to the Ninja World's Black Market and buy ninjutsu scrolls during their week ashore.

• A Marine officer named Isuzu boarded the Spade Pirates' ship, but Ace defeated her and sent her back without harming her.
• Isuzu warned Ace that a Vice Admiral would be sent after the Spade Pirates, and Yota worried about the crew facing the officer's elite forces.
• The Spade Pirates reached Jungle Island, where Ace gave the crew a week to explore and assigned Miharu to guard the ship.
• Yota decided to use the week to visit the Ninja World's Black Market and buy available B-rank ninjutsu scrolls.

Yota visited a Black Market to buy ninjutsu, using gold from Drum Kingdom to pay a deposit. After he left, several Bounty Hunter Ninja followed him, and they prepared to attack once he was beyond the Black Market’s protected perimeter.

• Yota searched his father’s record scroll for Black Market locations and entered one to purchase ninjutsu.
• Yota paid the owner a gold deposit and ordered every technique in the catalog that he could use, including the expensive Mystical Palm Technique.
• The owner told Yota to return in three days and warned him that several men had followed him outside.
• Yota continued roughly three kilometers from the Black Market, unconcerned because he believed his strength surpassed that of most Bounty Hunter Ninja.
• The Bounty Hunter Ninja decided to attack Yota, mistaking him for a weak young shinobi.

Yota killed three of the four Bounty Hunter Ninjas who ambushed him and discovered that consuming corpses let him extract some of their Chakra. After gathering ninja tools and Chakra Metal, he returned to the Black Market and bought the Medical Ninjutsu scrolls he had ordered.

• Yota caught the Bounty Hunter Ninjas’ kunai and pursued them, killing three while the fourth escaped wounded.
• Yota extracted Chakra from the three corpses, found the amount gained was small, searched the bodies, and buried them.
• Yota spent three days buying ninja tools and a piece of Chakra Metal while other bounty hunters became wary of him.
• Yota returned to the Black Market, checked the Medical Ninjutsu scrolls, and paid the owner for them.

• Dalmatian crushed Yota’s kunai and rushed him, and Yota countered with Chakra-lit bone spikes extending from his fist.
