Little Glee Monster's Serina has resumed her activities. The group will digitally release their new song "REUNION" on June 25, and all five members will participate in their nationwide tour 'Little Glee Monster Live Tour 2020→2021 ＞BRIGHT NEW WORLD＜' to start on June 28.

Last December, Serina halted her activities to receive treatment for ill health. Then last month, she revealed that she has been battling bipolar disorder and ADHD.

The group's new song "REUNION" was written and composed by Takai Ibuki, and arranged by Kimishima Ohzora. Its lyrics express the miracle of the five members meeting and singing together.

As for their tour 'BRIGHT NEW WORLD,' it's a hall tour consisting of 32 shows that was originally scheduled to be held in 2020. For the time being, Serina will refrain from appearing in front of the media, and will prepare herself for this tour. She commented, "I am finally able to see everyone. I am looking forward to spending time together after a long time."
