A video starring the members of Kanjani8 has been uploaded onto Johnny's & Associates' official YouTube channel. 

This video is a part of Johnny's project 'Johnny's Smile Up! Project' in an effort to help prevent the spread of COVID-19. To their viewers at home, Kanjani8 suggests telling an ad-lib fairy tale. Then they get into character to tell their story of how "Momotaro's descendants get into a quarrel during a remote get-together, which results in everyone crying at the end."
