Natsuki Sasahara  

, 笹原夏姫

Natsuki is a 17-year-old individual who possesses both human and cat-like features. She is the offspring of a human father and a nekomata mother. Natsuki is known for her compassionate nature, always ready to lend assistance and protect those in need while adhering to the law. When provoked or frightened, her tail splits into two. Natsuki boasts about owning an orihalcon blade and being in command of two "parasites," which is quite unusual for this setting; even having one is considered impressive. According to Wikipedia.
