After completing another batch of Extremis Virus experiments, Tsunade and Karn returned to Konoha, where Karn stayed at the Senju Clan Compound for safety. Kushina was delighted to see Karn and the gifts he had brought, and they sat down to dinner with Nawaki and Tsunade.

• Orochimaru used Karn's serum to begin thirty simultaneous Extremis Virus experiments, and Karn gave him another vial when Orochimaru asked to trade for one.
• Tsunade and Karn set out for Konoha so Tsunade could check on the Medical System Reform and bring Nawaki back if the experiments proved successful.

Danzo tried to persuade Hiruzen to seize Karn and ask Tsunade about treating his injuries, but Hiruzen refused to act without more intelligence and only promised to speak with Tsunade. At the Senju Clan Compound, Tsunade told Nawaki that a treatment was being prepared for him, while Kushina later confided to Karn that she feared becoming a monster.

• Danzo brought pills reportedly sent from Kirigakure to Hiruzen and urged him to act against Karn.
• Hiruzen refused Danzo's proposal to seize Karn, citing the lack of intelligence and the danger of provoking him.

• Karn returned to his guest room and planned to meet Nanami and recommend Yakushi Nonō to Tsunade.
• Kushina visited Karn late at night and asked what she should do if she turned into a monster.

Karn eased Kushina’s fear of becoming the Nine-Tails Jinchuriki by teasing her over an unpaid dessert bill, then gave her candy. The next day, Tsunade accepted Yakushi Nonō as a student, and Karn set out to visit the Uchiha Clan, leaving Tsunade outside the compound.

• The Root captain ruled out ordinary techniques, suspected space-time ninjutsu, and ordered the operatives to report to Danzo-sama.

Hiruzen learned that Nawaki had mastered Wood Release through the Extremis Virus Serum, but the serum was gone and Karn had refused Konoha’s offer. Tsunade and Orochimaru kept Nawaki out of missions for now, while Hiruzen planned to wait for Root’s return and Nawaki compared Tsunade’s colleague Dan Katō unfavorably with Karn.

• Hiruzen saw Nawaki use Wood Release and regretted not securing the serum’s experimental data, while Orochimaru said no serum remained and Karn had refused to join Konoha.
• Orochimaru agreed to keep Nawaki with him and let Tsunade train him in Wood Release, while Tsunade rejected Hiruzen’s suggestion that Nawaki team up with Kushina.

• Nawaki asked whether Dan Katō was Tsunade’s suitor and said Karn suited her better.

Karn considered how to build his power and businesses in both the shinobi and Marvel worlds, then brought new extremis virus research to the Biological Research Center. He presented Killian and Maya with a new serum production procedure as they argued over the stalled experiments.

• Karn weighed ways to protect himself from Danzo and Root, while the system showed that a search for another world might succeed within a month or two.
• Karn removed Hashirama cell material and human experimental data from his virus documents before heading to the Biological Research Center.

Karn persuaded Maya, Killian, and the researchers to pursue a new direction for the Extremis Virus experiments, then managed his growing businesses and recruitment plans. After reviewing the pharmaceutical wholesale company, he learned that the Trading System had unlocked a search for a new trading world.

• Karn told Maya, Killian, and the other researchers that an experimental method had succeeded and urged them to investigate regenerative cells from organisms such as salamanders or geckos.
• Karn refused to reveal the test subject or data, then encouraged Maya and Killian to continue researching the Extremis Virus and prepare to reduce its potency and cost.

• Karn struggled to buy dragon blood and other magical-creature materials legally, so he decided to visit Knockturn Alley.

Karn used Borgin and Burkes to arrange a purchase of rare magical ingredients and a repaired cabinet, then intimidated Knockturn Alley after his shadow clone exploded during a confrontation. Back home, Hermione showed Karn her Cure for Boils Potion, and he asked her to deliver a letter to Dumbledore when she started school.
