King in Yellow in Japanese Fantasy?

A number of vague online mentions are claiming that Japanese writer Miyuki Miyabe's new book The Book of Heroes contains a villain from classic weird fiction. Namely, Robert W. Chambers' creation, the King in Yellow, is said to haunt the pages of this fantasy novel. How this weird icon is put to use in Miyabe's story is anyone's guess, but this description from the publisher's site suggests it may be a path not regularly seen in traditional weird fiction:

When her brother Hiroki disappears after a violent altercation with school bullies, the young Yuriko finds a magical book in his room. The book leads her to another world where she learns that Hiroki has been possessed by a spirit from the Book of Heroes. She visits the magical Nameless Land, where she is told how to save her brother, and is sent back to Earth with a young monk named Sora and the magical book...

When this book makes its scheduled appearance next year, it should be of definite interest to chroniclers of weird fiction. The use of a relatively obscure weird figure in fantasy--from a foreign source, no less--is an unexpected development. It's also worth noting since it could support the idea that Carcosa's King is enjoying wider popularity, spreading his maddening taint to new nests of pages.
