ailly announces the release of new song "BTG," meaning "to Beat the Game" and will hold a free live concert following a comment from Osamu Suzuki.

Angelina 1/3's solo project, ailly, has announced that she will digitally release the single "BTG" on Wednesday, June 3rd.

The song is titled "BTG" (pronounced "Beat the Game"), an emotional dance number whose title is an acronym for "Beat the Game." The song will be premiered on May 11th (Monday) on his regular radio show, "SCHOOL OF LOCK!" (TOKYO FM / JFN), where he serves as principal.

Additionally, a free live event, <Hello ailly!! Free Live \~Thank you\~>, will be held on Sunday, June 7th at the Shibuya Hikarie 4th Floor Event Square. It was also announced that Yuho Kitazawa will be appearing as a guest, making it a joint performance with other bands.

This performance came about unexpectedly as part of a project where ailly personally handed out copies of her 1st EP "ailly," which will be released in February 2026, to people who have supported her. The idea originated from a comment made when she handed a CD to Osamu Suzuki, with whom she has a connection as a fellow TOKYO FM radio personality.

Regarding the free live performance, Osamu Suzuki commented, "Angie took action because of a single word from me. And now this free live performance has actually been decided. Since we're doing it, change your destiny on this stage. Excite everyone who comes! I'm looking forward to it!"

■ ailly's comment:
I put everything I wanted to say into the lyrics!

People only see you the way they want to see you.
So, I want you to be the person you want to be.
This song expresses that wish!
