This is a major turning point for Rin’s character. Up to this point, she’s been fairly intent on seeing others’ humanity, respecting it, and protecting it. But here, she decides it doesn’t matter if Altan/the chimei is in fact a fellow human being, and even one that she loves—she’s going to kill him anyway. With this choice, Rin begins to lose some of her humanity, even as she arguably does her country an immense service by dispatching the chimei. In contrast, Nezha becomes more human and sympathetic as he reveals what happened with his brother and apologizes.
