Formerly "Japan's Strongest". A woman called a "genius". She usually wears a green kimono and looks very fragile. He's a super roadie. With the eye of genius "Mian Ji Gu", he can instantly master almost all the ninjutsu, moves, skills, illusions, words, physiques, blood inheritance limits, etc. He has seen. If you read it once, you will roughly remember it. If you read it twice, you will remember it in your mind. My practice is to see, and my cultivation is to see. Has super high combat effectiveness. The "Sickness 100 Million" exists to balance the "Jianjigu", so that Nanami is only a thin line away from death at any time. Since the body is a genius's body, I also said that my body will not choose to die on its own. Instead, it allows Nanami to forget pain and become immune to poisons as long as they are not fatal, making his strength even higher. Before Nanka was born, her father originally named Nanami as the next heir of Kyūdōri, but at that time Rokuge discovered that Nanami's potential ability was too strong, and instead transferred the inheritance rights to her younger brother Nanka. Although Rokuge did not teach the Kyon Sword style, Nanami watched while Rokuge taught Nanka, and learned the Kyon Sword style through her ability to remember it after seeing it once. Weaknesses include lack of physical strength and lack of endurance. Nanami had experience in dueling with her younger brother Nanka in the past, but because she was exhausted at the time, there was no winner. But at that time Shichika also discovered how powerful Nanami was. After obtaining the "Evil Sword 'Ku'" from Mutsu Death Soul Mountain, he made up for his lack of physical strength and became the true "strongest"...
