Rainbow Signal

 (虹信号) is an idol group based in Laguna, Philippines. The group's concept is "Be a signal of fun". Established in 2018, the group has gone through multiple member changes, with auditions being held to look for new members.

History
The group was established in 2018 in Laguna. The original members, Mikan, Ninenyan, and Karma were recruited, and spent several months preparing for their stage debut. The group made it's stage debut in Pinoy Otaku Musika, an event by Red Cloud Interactive at Tiendesitas. It was followed up by a performance at Ozinefest Anime Figure Special.

Karma, the red member, graduated on the 1st of January, 2019 in order to focus on her studies. Mikan and Ninenyan continued as a group, and performed at Hobby Expo 2019, an event organized by Minoki, a student organization. Eventually, the group opened auditions for their 2nd generation members, which yielded three members, Kaeru, Akari, and Tomoko. The members were unveiled in 2020, with their first appearance at ElbiKon. The new line up made their debut at Otacute's Anisong Festival. Unfortunately, due to the pandemic, all plans of the group took a backseat.

Since then, the group and its members has taken part in various collaborations - Akari represented the group in Melancholiaah's "The World's Idols - see you soon collaboration". As well as taking part in Pastel Mix's Aidol Hatching Time.

The group released their first digital song and their first music video 飛ぶゴキブリから逃げろ (Tobu Gokiburi Kara Nigero/Run away from the Flying cockroach) last June 24, 2022.

In August 27, 2022, the group opened their auditions once again. The auditions, dubbed 「Rainbow Signal 新メンバー　未来少女オーディション」(Rainbow Signal New Member - Mirai Shoujo Auditions) underwent 3 stages, with 2 stages being done remotely, while the last one being done in person. The winner of the auditions, and Rainbow Signal's 3rd generation member, is Reio. Reio first appeared with the members of Rainbow Signal last December 2022 on the Rainbow Signal Online Live.
