Published February 22, 2017
Confession Executive Committee ~Idol Series~ is a collection of songs detailing the work and daily lives of idols in the Confession Executive Committee universe. Originally a part of Confession Executive Committee ~Love Series~, this was officially recognized as its own spinoff in 2019.


This title began in the Love Series, as its inaugural song "Romeo" was originally featured as an insert song in the Confession Executive Committee movie I've Always Liked You., where its protagonists also make a cameo. At the time, and for at least a year, the focus of these videos would be about the idol duo LIP×LIP, a teen sensation that's gotten very popular in Tokyo. Later installments would introduce other performers that work with them, such as mona, a rival soloist; and Minami, a friend and Youtuber that sings with them on occasion.

However, the characters did not originate from "Romeo" alone. Song-wise, Yujiro was first introduced alongside classmate and future love interest Hiyori Suzumi in the Love Series song "Koi-iro ni Sake", while mona was originally featured in "Kawaiiku Naritai".

Manga SerializationEdit

As with many Confession Executive Committee properties, this series has received a voiced comic in HoneyWorks' fourth studio album Nando Datte, Suki. ~Kokuhaku Jikkou Iinkai~ as a "Prologue" comic to Romeo.

A serialized manga concerning the rise of Mona Narumi as a popular idol was released in December 2019 on the digital manga magazine Piccoma, based off of the song "Watashi, Idol Sengen". The manga is available for free reading for the first three chapters, and debuted on January 15, 2020.


Events in the Idol Series have been novelized as part of the Confession Rehearsal series starting from the 11th installment. Watashi, Idol Sengen, a separate novella focusing on Mona, released as a bonus for the CHiCO with HoneyWorks album Watashi no Someru i no Uta.
