Hanako: "I begged you not to eat that scale! Remember?"

Hanako: "you"

Poke!

Hanako: "Did it"

Poke!

Hanako: "Anyways!"

Poke!

Hanako: "I also told you not to use the scale on that boy, you listened, which means I can still grant you a wish." Said, making it clear that you were gonna have to use your wish up to turn human again.
