Part 1: Keita tries to explain Golden Week to Jibanyan, but he is not interested in the holidays. Whisper comes into the room and reveals he has a gift for Keita for Golden Week, a special protective charm that wards off Youkai, as they come into the... (more) human world more often during this time.

Keita calls on Robonyan to make Amefurashi stop, but Robonyan opens up a time portal to go to an electronics store when there is a sale to buy a vacuum cleaner first, using himself to power it up to suck up the clouds, but instead he sucks up Whisper. Robonyan turns off the vacuum and launches a Rocket Punch that strikes Amefurashi, causing her to run away in pain, and the rain to stop. Keita wonders why the protective charm has not been working, and Whisper reads it to discover it only works on butler-t
