Nobunaga was a skilled warrior during the Edo period in Japan and possessed an exceptional talent for using his long Japanese sword with precision and skill. His specialty lay in executing enemies swiftly and efficiently, earning him the nickname "King of Carelessness." Franklin admired Nobunagas abilities and considered him to be one of the most skilled swordsmen of his time. Ubogin was Nobunagas closest friend, and their bond strengthened each other's combat skills. Although Gon shares some similarities with Ubogins personality, he refused to join the Ryodan despite being approached by Nobunaga. Nobunaga is a member of the Genei Ryodan, which originated from Ryūseigai.
