Saved by the sleepiness of the Demon King once again.

- Turn evil...
- oh no, my feathers are turning darker! noooo!
(The Demon King's magic has affected the Harpy!)

oh no Yume's been altered!
-Ku ku ku, Hero! Listen to my song and sleep for all eternity!
La a a a

La la la la la
-Well, Hero? How do you like the pervasive power of my song?
- Somehow, I'm getting sleepy...

-huh? what.... what was I doing?
(The Demon King has fallen asleep!
Harpy has returned to normal!)

And thus the power of the Demon Lord was sealed in eternal slumber

So long, Hero Ranko! At least, until the Demon Lord awakens once more!
