@Ichigo69 Yeah, it doesn't spoil anything if you've read the novels. But if you're just following the story via the manga, at this point you don't know whether she'll be a major ongoing character or turn up dead in the next chapter (for example). That's all I meant.
You can tell from the beginning of the manga that she's a major character in this thing. She's the reason Torako's even going to the Otherside in the first place. You're thinking too hard about it.
This is the point where I really started liking Kozakura. Not that I didn't like her before, but she was just another side character - this section is where she becomes a fun and interesting side character . . .
