They are a group of henchwomen who work for the evil Tamayomi (たまよみ) clan (also known in some versions as the Clan Of The Cataplines). They are led by an old woman called Nakamura and work out of the hostess club that she owns. They are skilled in gymnastic martial arts and attack with deceptively powerful ribbons that are able to slice their way through objects you wouldn’t expect them to. They work under the command of the evil Majo, who is the deputy head of the Tamayomi clan.
Just like their superior, they dress in tight minidresses with jackets, sunglasses and high heels. Their outfits catch the attention of Shin Chan’s dad who excitedly describes some of the bad girls by saying “They had these tight miniskirts. And up front was so open you could see their cleavage!”.
The Tamayomi clan are hell bent on getting their hands on a magic ball that can unleash the imprisoned Devil Jack, they have the goal of taking over the world with Devil Jack’s evil power. At the start of the movie Majo and the Hostess Corps greet a fellow clan member at the airport, where he has flown in after obtaining the ball. But before the Tamayomi clan can leave with the ball it is stolen by a rival clan called the Tamayura. The Tamayura are the good guys and are trying to stop the ball falling into the wrong hands. The Tamayura characters who we see most on screen are 3 transvestite siblings. Majo and the Hostess Corps attack the Tamayura clan in the airport, but the good guys manage to defeat them and get away with the ball.
The following day, the Tamayura clan go into a town occupied by the main protagonist Shin Chan and his family. Shin Chan meets one of the Tamayura by the water and ends up taking the ball from him. The Tamayura soon realises it is missing and tracks it down later that evening to Shin Chan’s house where it turns out his baby sister Himawari has swallowed it.
The rest of the movie involves the good Tamayura clan protecting Shin Chan’s family and trying to get the ball out of his baby sister, with the evil Hostess Corps and the rest of the clan on their trail. The two clans battle inside clubs and even a supermarket, where Majo and her goons manage to capture two of the Tamayura siblings. They also eventually capture the baby Himawari later on as well.
In the final battle the Hostess Corps fight Shin Chan’s family, the Tamayura clan and even their fellow clan member Satake, who betrays the group by returning the kidnapped baby to her family after feeling guilt. The Hostess Corps are defeated off screen by Satake and later shown knocked out on the floor along with their boss Majo. During the credits, it is revealed that they and the rest of the evil Tamayomi clan members were arrested and placed in jail.
