Kisara runs Tendou Civil Security and comes from the Tendō family, though she left years ago following a falling out—taking her childhood friend Rentarou with her. Her kidneys are in rough shape after witnessing her parents get killed by Gastrea, an experience that left her convinced the Tendou family bore some responsibility. That trauma sparked her desire for revenge.
She's genuinely talented with Tendou-style martial arts, but her deteriorating health means she can't sustain fights for very long. Despite being skilled, her body just doesn't hold up.
Both she and Rentarou clearly have feelings for each other, but neither of them has managed to actually say it. They lack the nerve—or maybe just the right moment—to make a real confession.
