REGALITY, the first full album by the Idolish 7 franchise's in-story male idol group Trigger, sold about 32,000 copies to top Oricon's weekly album chart for the September 18-24 week. This makes the album the first one credited to a male in-story character group to top the weekly album chart. The album shipped on September 20.

The K-ON! franchise's Ho-kago Tea Time group was the first in-story character group to top the weekly album chart in 2010, followed by Love Live!'s μ's in 2015 and The [email protected]. Kemono Friends' Dōbutsu Biscuit x PPP also achieved the feat in June earlier this year. However, all of these earlier groups were female in-story character groups.

Bandai Namco Online made the Idolish 7 "dramatic rhythm action" iOS and Android game with music in collaboration with Lantis. The player assumes the role of Tsumugi Takanashi, a manager for a new idol group. She must train seven male singers — each with their own individual personalities — to turn them into the No. 1 idols. The game features full voicing of the dialogue by the cast.

The multimedia project includes multiple manga adaptations, as well as an upcoming television anime and spinoff series. Arina Tanemura (Full Moon O Sagashite, Phantom Thief Jeanne), the project's original character designer, drew the IDOLiSH 7 TRIGGER -before The Radiant Glory- manga with a story by Bunta Tsushimi, and the pair launched Idolish 7 MEZZO: Murasaki Ao no Hekireki in Hakusensha's LaLaDX magazine in October. Nokoshi Yamada launched another manga on Hakusensha's "Hana LaLa online" site in July 2015. Tsushimi also launched the novelization on the Web Hakusensha Novels site at the end of July 2015.

The television anime will debut in January 2018.
