Botan Shishiro, a VTuber from hololive production.

Written, composed, and arranged by sasanomarie, this track fuses an electronic texture with a lyrical melody.

While depicting the blurring boundary between oneself and others, its lyrics express a determination to protect precious relationships, quietly resonating with people living in modern society.

It’s a song you’ll want to listen to alone at night, taking your time.

GRe4N BOYZ / “Poem of the Stars” Lyric Video

This song by GRe4N BOYZ was newly written as the ending theme for the 5th National High School Light Music Club Tournament, “we are SNEAKER AGES.” Released in December 2025 as a cheer song for light music clubs at 2,400 schools nationwide, its exhilarating sound and irresistibly bright melody affirm the youthful days devoted to club activities.

A key highlight is that TERU from GLAY participates on vocals.

The piece embodies the shared sentiment between GRe4N BOYZ—formed with friends from their school days and still active—and GLAY: the value of the “view shared with your friends.” It’s a must-listen for anyone striving toward a goal.

Released in December 2025 as a track on the second album “MAGenter,” this song is a mysterious love ballad dominated by strings.

The tension and shading created by the string instruments evoke images of the moon, stars, and night, beautifully portraying the way two people are drawn together in romance.

During recording, the direction was to “sing as you are,” resulting in a free and joyful atmosphere in the studio.

It’s a perfect fit for those who want to experience a mature love story.

The lead track from their fourth single, built around the theme of the moon.

Released for streaming in December 2025, its sound moves between a dreamlike mood and raw passion, vividly reflecting the group’s duality.

Like the moon that changes shape as it waxes and wanes, the song expresses moving forward even while carrying imperfections and the parts of yourself you’ve kept hidden.

It’s a track I especially recommend to anyone searching for their own true self.
