   Summary

   In the mystical heart of Japan, where ancient traditions and modern life intertwine, Hermione Granger has embraced her destiny as an Onmyōji— magical guardian of Japan and the spiritual realm. For over ten years, she has honed her skills, helping lost souls, protecting the living from malevolent spirits, and guiding and fixing the magical flows. Her world is turned upside down when Healer Potter arrives looking for help to save Sirius, trapped in the in-between. Hermione and Harry embark on an extraordinary journey across Japan to the sacred mountains, where ancient spirits whisper secrets and the boundaries between worlds blur.
