Kyōryū Sentai Zyuranger
On the cover and in the music video all members are wearing costumes in the style of "sentai heroes", main protagonists of Japanese television series in a genre called "sentai". The sentai genre (the word "sentai" means literally "squadron") evolves around a team of costumed superheroes fighting villains and includes such popular television shows and franchises as "Kyōryū Sentai Zyuranger" (remade into "Power Rangers" for the US), "Kamen Rider", "Ultraman", "Metal Hero". The music video is also reminiscent of sentai films. In the video, the girls use transformation belts to become helmeted fighters looking like sentai warriors, and the Weekend Heroines squadron fights fully armed with a song and a dance. The protagonists of the superhero genre usually have transformation belts ("henshin beruto") or some other transformation items (like rings, swords, etc.), which they use to transform into superheroes in armored suits. Momoiro Clover Z transformation belts are clover style.
