NTV "Zoom-In Super!" Hosts Hatori Shinichi, Nishi Yukari and Ohguma Mika was featured in Tohoshinki's "Kiss the Baby Sky" PV because Tohoshinki's Yuchun promised that they'll arrange them to film in "Kiss the Baby Sky" PV.
The hosts of NTV "Zoom-In Super!" once interviewed Tohoshinki and one of the hosts casually said that he wanted to be in their PV. "Kiss the Baby Sky" by Tohoshinki was used as NTV "Zoom-In Super!" theme song.
