This series has examples of:
- Adorable Abomination
- Cute Monster Girl: Horribly subverted; the cute appearance is an act; and she ultimately sacrifices Mizuki to her mother and shapeshifts into her.
- Downer Ending: Mizuki is eaten by the spider's mother, and the spider-child masquerades as Mizuki without anyone being the wiser.
- Giant Spider
- History Repeats: The same events happened to the monk. The current day cast even read about it.
- I'm Taking Her Home with Me!
- Nature Versus Nurture: Nature wins...Not that there was even a fight to begin with.
- The Scorpion And The Frog
