Mein Schulgeist Hanako 05

The tone shifts between eerie and lighthearted, which keeps the story unpredictable. I'm curious about how the balance was struck during creation.

The ghosts and mysteries seem so thoughtfully developed. What do others think about the world-building behind these spirits?

The setting feels like a character itself, full of secrets and history. I wonder if the author drew from specific legends or created everything from scratch.
