L'Arc-en-Ciel will digitally release their new song "Mirai" on May 31.

The other day, L'Arc-en-Ciel announced that they would be premiering a video via their YouTube channel on May 29 at 12:00 am JST. When the clock struck midnight, a powerful message stating, "Let's hang a rainbow. Many times," along with a new artist photo were revealed. Then, a clip of "Mirai" and its lyrics were unveiled. The last song that L'Arc-en-Ciel released was "Don't be Afraid" back in December of 2016, making this their first new song in four and a half years.

The band will hold their 30th anniversary live '30th L'Anniversary Starting Live ~L'APPY BIRTHDAY!~' on May 29 and 30 at Makuhari Messe.
