The manga version of Onidamashi contains some differences:
- The scene at the beginning of episode 2 with an older Rika meeting Hanyuu is moved to the end of the arc. It is also changed to where Rika is no longer a teenager but also expands on the scene and references the events of the original story.
- The renovation of the Irie Clinic is not shown.
- Keiichi is shown recalling more memories from Onikakushi, such as the scene with Rena at the door and the true events of Rena's death as described in Tsumihoroboshi.
- The first novel volume of Kataribanashi-hen contains a story with the exact same name, but this is likely a coincidence.
