One of the strongest and deadliest Swordswoman in Squad. Natsumi is a cold-hearted, steady-focus member who will slice everything like it's her slaughterhouse. Her Soul Ki contains Cherry Blossom Spring, using her katana to create wind cuts for almost every strike.  Even though she and her team would eventually help the Raiju Nefilims, she holds a strong grudge against Keiran for beating her in a one-on-one Kendo Dual as she claims "he lacks steadiness and relies too much on agility".
