The five Toreishi sisters, Kanna, Yayoi, Satsuki, Uzuki and Mina, are teenage idol singers who are collectively known as The Hummingbirds.
When they aren't saving the world from major overseas threats, they are on stage in frilly dresses, pursuing their idol career.
Ostensibly led by media darling and fan-favourite Kakkun, the team had a huge following of rabid fans, despite their incompetence in the air.
They have gone up against the Toreishi sisters twice—in their first encounter, the girls were contractually obliged to play sitting ducks, but the lengths to which they went to present obvious targets got them noticed.
In the Western hemisphere, Idol Defense Force Hummingbird was published in the UK as a subtitled VHS video combining the 93 and 94 episodes in 1994.
