Arc 1Karn Builds His Shinobi Empire
Karn used the Trading System to bring medicine, food, and business ventures to the Shinobi World, gaining Konoha’s trust while expanding his influence. As Tsunade developed a Medical Ninja program and Nawaki was injured, Karn prepared to recruit Kakuzu and establish a casino and confectionery shop.
- Karn entered the Land of Rain during the Second Shinobi World War, met Yahiko, Konan, and Nagato, and brought them to Tsunade, Jiraiya, and Orochimaru.
- Karn sold Konoha his medicines, secured permission to open shops, and hired Senju widows to staff his business.
- Karn established companies in New York, returned with supplies, expanded his Konoha shops, and arranged a factory and cocoa cultivation in Kawaki Town.
- Karn sold novels in the Land of Fire’s capital, built the confectionery factory, and arranged for villagers to grow cocoa in exchange for grain and high-priced bean purchases.
- Tsunade sought Karn’s advice on a Medical Ninja training proposal, then worked with Yano and Aosuke to develop a detailed plan.
- Tsunade operated on Nawaki and stabilized him, though she knew he would probably never serve as a ninja again.
- Karn baked Kushina a custom cake for Nawaki and then set out to recruit Kakuzu as a casino manager and enforcer, while giving Xia Chuan money to establish new shops and support homeless children.
