After participating in SKY-HI’s audition “THE FIRST,” REIKO has honed her craft as a solo artist under BMSG.

Released digitally on January 12, 2026, “Lullaby (Prod.

ALYSA)” was selected as the January ending theme for the TV program “Hiruobi.” Produced by ALYSA, the track blends a nostalgic band sound with piano to create a warm yet wistful atmosphere.

The lyrics, which dwell on lingering feelings for a former lover, delicately portray regret and prayers for time that can’t be reclaimed.

It’s a song that gently stays by your side on sleepless nights when memories resurface.

With a tender yet resolute vocal delivery that resonates deeply, it’s a superb ballad number.

tuki. “Kotonoha” Official Music Video

This warm, message-driven song portrays the power of words as seeds that, given time, bloom in the heart.

Singer-songwriter tuki., who made a sensational debut in 2023 with “Bansanka” and has continued to captivate listeners with her voice, wrote this piece as the theme song for the drama “No Mistake, He’s My Husband,” starring Nao Matsushita, released in January 2026.

The gently confiding melody, which seems to nestle close to the story, also aligns with her mysterious aesthetic as an artist who maintains anonymity.

The sound, which cherishes the lingering resonance of words, is something you’ll want to listen to on sleepless nights troubled by relationships, or when you wish to convey your feelings to someone important.

Vocaloid producer Yasumi Suya, a creator who expertly employs wordplay and typographic gimmicks, has earned passionate support.

Released in February 2024, this work became a hot topic, ranking 98th in the Bokakore 2024 Winter charts.

The concept is brilliant, centering on the letters in the song title and sprinkling in terms related to scoring and evaluation.

It deftly portrays a satire of the visible numbers and buzz mechanics of internet society, set to a rapid beat and electronic sound.

It’s also spreading through short-video arrangements and covers, and its addictive rhythm is irresistible.

Anyone feeling worn out by the internet’s evaluation economy is sure to find it exhilarating!
