Actually each folk tales symbolize(summarize) the previous episode(1 to 8) that we watched....
Even If you don't know Japanese Folk lore,you can still barely somehow connect to the previous episode ^^
( because my brain doesn't has a good memory,so this episode is quite refreshing for me )
It literally took me a week to find the proper amount of boredom to finally watch this episode, and even then I had to stretch it over the span of two days. God what a terrible 23 minutes. If I was a die-hard fan of the manga, I probably would've enjoyed it... but I'm not. .-.
