This was a Halloween special (second week).
The broadcast last week was a Halloween special too.

Aimi and Haruka were wearing the pink and black outfits that Pyxis wore for their CD Flawless. Aimi was Moe and Haruka was Miku. Haruka even wore a wig, and had the make up artist do her make up like Itou Miku.

Aimi and Haruka said that they were surprised that they were able to fit inside the actual outfits. But they said they wouldn't be able to sing and dance because it was too tight.
