Nanami Yasuri

Nanami Yasuri is the daughter of Mutsue Yasuri and Migiri Yasuri and the elder sister of Shichika Yasuri. She is the seventh opponent he fights for the Deviant Blades. Nanami is a slender girl who resembles her mother Migiri, with long dark green hair that is decorated with pink markings of cherry blossoms and purple eyes. After leaving the island, she changes into her monk-like outfit of black and purple monk sashes, silver armbands under her long black sleeves, white/mint green stockings, a pink choker, and slippers. Nanami is depicted as a gentle and soft-spoken girl who seems weak, but she is actually very strong. However, she is downright terrifying to face during a fight. She displays a critical lack of basic human understanding or empathy, much like Shichika did early on in the series. However, Nanami's disregard for basic human values is even more severe than Shichika's, possibly due to her father trying to kill her. She also flashes very creepy and dark smiles on occasion, hinting at a bloodthirsty nature that lies beneath her fragile exterior. As the seasons go by, her inner murderer gains more sway, and she becomes noticeably insane and even fatalistic, in part due to the increasing suffering her body is undergoing. Deep down, all she wished for was to perish peacefully by learning Kyotōryū through her main ability, "Perfect Observation," without being taught the technique, which could also take away her strength little by little.
