Billlie's Tsuki on variety shows, Tokyo store visit, and life after the group's first full album

Shibuya stop, then back to the timeline

On the 8th, Tsuki posted photos from a brand store in Shibuya, Tokyo that had just reopened after renovation. "The store newly reopened for renovation so I went to visit," she wrote.

Months earlier, Billlie dropped their first full-length album, the collective soul and unconscious: chapter two, on May 6, 2026. The 12-track record includes title track ZAP plus WORK, $ECRET no more, TBD, B'yond me, SOUPASTA, OFF-AIR, and the Japanese mini album 1 title track DOMINO ~ butterfly effect with its remix. Siyun (Kim Si-yun), the group's main rapper and lead dancer, summed up the album in one word: "자각" (self-awareness). It contains content about finding answers about oneself.

From direct cams to MC chairs

Tsuki is Billlie's main dancer and sub-vocalist. Her direct cam for GingaMingaYo (the strange world), released February 25, 2022, crossed 15 million views. That's the second-highest view count among 4th-generation girl group direct cams.

Her variety résumé runs deep. She appeared on MBC's King of Masked Singer twice in October and November 2022, becoming the first Japanese female participant to advance to the second round. She also hit Amazing Saturday - Do Re Mi Market, SBS Running Man, and MBC Radio Star. Then came the MC slot for MBC M Show Champion in 2023.

Netflix brought her on as fixed cast for Zombieverse (2023) and Zombieverse: New Blood (2024). In 2025 she joined Extreme 84 as a running mate and landed the MC gig for Walk Dol Season 4.

Fall schedule and the unit side

This fall, Tsuki participated in a collaboration photo shoot between an online fashion brand and a Japanese magazine, covering 'dreamcore' and 'futuristic gal' concept looks.

Siyun and Moon Sua released unit single SNAP on April 7, 2025 (Siyun co-wrote the lyrics), with SNAP (feat. sokodomo) and an English version also included. Tsuki debuted in Japan with MAGICOUR's single MAGIC in 2020 before Billlie's Korean debut on November 10, 2021 with mini album 1 the Billage of perception : chapter one. She is from Awaji City, Hyogo Prefecture, Japan, and was born September 21, 2002.
