Toilet-bound Hanako-kun T13

The backstory behind Hanako feels layered and intriguing, but I wonder what the author envisioned for his past and motives.

The mix of humor and horror kept me on edge, but some scenes felt quite intense. How do others interpret the balance between spooky and fun here?

The way the spirit world interacts with the human world adds complexity. I'm curious whether the author planned out these rules from the start or developed them as the story progressed.
