Nobunaga fights like a masterless samurai from old Japan, wielding a long Japanese sword with impressive precision. He's known for his deadly swordsmanship—executing enemies is basically his whole thing. Franklin's even called him the "King of Carelessness," which probably says something about how he operates. His closest ally is Ubogin, and they push each other to fight better together. Nobunaga saw shades of Ubogin's personality in Gon and wanted to recruit him into the Ryodan, but Gon wasn't interested. He's a core member of the Genei Ryodan, originally from Ryūseigai.
Beyond pure sword skills, Nobunaga uses En to set up a circular detection field around himself. The moment an opponent crosses that boundary, they're getting hit back immediately—it's a pretty solid defensive strategy that makes him harder to catch off guard.
