SMILE ♥ X was formed as a rival group for the veteran idol group Cherry 7, who were working with the Rougai Party to end the practice of idol Diet-women. The group was a collaboration between all the current idol diet-women, proposed by Shizuka Onimaru. All the current idol Diet-women audition for a role in the group and Mizuki Fudou chose the final 9 members.

SMILE ♥ X and Cherry 7 competed against each other and SMILE ♥ X (without Natsuki Hoshina) earned the support of the Japanese public, winning the contest, but were unable to stop the passage of the Idol Diet-woman Prohibition Bill.

Unit Outfit

Each girl wears a matching yellow dress wih frilly white detail to match the fabric covering the chest. They also wear frilly wrist accessories and boots with a pair of knee-socks with a blue ribbon sewn to the side to match the blue accenting of the outfit. On the lower right corner of the top and upper left corner resides a black clover ornament. Each girl also wears a white and yellow cap with a ribbon sewn to it. The ribbon is colored to match the sash draped around her right shoulder and chest. 


  • The Heroines Party is the party with the most members represented in SMILE ♥ X (and is the only party which all of its current members passed the audition).
  • Natsuki Hoshino was absent from the group's debut performance. The remaining members wore hats with ribbons in her member color (red) rather than their usual colors in her honor.
  • Every Party featured in Idol Jihen has at least 1 representative in SMILE ♥ X, except for the Rougai Party.
  • The average age of this unit is 17 years.
  • Sachie Kondou and Shizuka Onimaru are the only members whose official colours don't match the official colour of their Party.
