An overwhelming total of 9.5 million followers both domestically and internationally. "BLACK DIAMOND" started its activities as an artist in March 2023.
Since Zepp Haneda on May 17, which ended with great success, BLACK DIAMOND has continued to prepare for further power-ups.
On October 22, they announced their first single in five months, I'll Shine, and at the same time, they released information about their first one-man live.
With this announcement, it can be seen that this long preparation period has been used to prepare for the new work and the next live performance.
And the distribution of the latest work has been decided.
Gainis an upper tune with all English lyrics.
No gains without pains. ~ There are no gains without pain. The girls sing. It's a song that gives strength to everyone who listens to it, a song that can only be sung by the girls who came together for this project, with long lessons and high hurdles to achieve!
