IDOLiSH7 7th Anniversary Event "ONLY ONCE, ONLY 7TH."

Background
ONLY ONCE, ONLY 7TH. was the sixth live by the IDOLiSH7 franchise, held at the Yoyogi National Gymnasium. It was a celebration of the franchise's seventh anniversary and it marked a special milestone as the number "7" is very a significant number within IDOLiSH7. The theme was "parade".

The project was first announced on January 7, 2021. Congratulatory messages from the original character designer Arina Tanemura, scriptwriter Bunta Tsushimi, and anime character designer Kasumi Fukagawa were released on August 20, 2022, the live's DAY 1.

The live consisted of many events. There were live CG performances of the characters wearing their respective outfits from the 7th anniversary key visual. IDOLiSH7 performed "Mallow Blue", Re:vale performed "Kokoro, Harebare", ŹOOĻ performed "Survivor", and TRIGGER performed "SUISAI". There was a live reading of the CROSSOVER ROTATION drama story, written by Bunta Tsushimi, that depicted the story behind the creation of the song "CROSSOVER ROTATION", created to commemorate the seventh anniversary. There was also a performance of "CROSSOVER ROTATION" by all 16 cast members using it as a way to introduce each other to the stage, various games and quizzes about the history of Ainana, a situation voice corner, and recitation dramas. Finally, the live was rounded off with a performance of Welcome, Future World!!!! by all 16 cast members.

Satomi Sato, who voices the character Tsumugi Takanashi (the manager of the group IDOLiSH7), was even present as a narrator as clips played recounting the events of IDOLiSH7 over the past 7 years. The dates for the starts of Part 6 of the game story and IDOLiSH7 Third BEAT! Part 2 were also announced.

Live viewing was held domestically and livestreaming was available in multiple countries.
