Nijisanji livers Sasaki Saku reached 1 million YouTube subscribers on August 12, 2026. The milestone was confirmed during a livestream that began at 7:00 PM JST, where Sasaki watched the count cross the threshold with viewers. Upon reaching the number, she shouted "Kitaaa" and thanked fans, saying "Thank you for 1 million." The achievement came after a false alarm on August 10, when the subscriber count briefly displayed 1 million before dropping back to the 990,000 range. Sasaki, who was away visiting family at the time, posted on X that the count had not actually reached the milestone, describing the jump from 990,000 to 1.02 million as suspicious behavior. She debuted on July 6, 2018, as part of the former Nijisanji Gamers, and briefly graduated in November 2018 before returning in January 2019. In June 2026, she updated her official visual from a student appearance to an adult look, and in July she marked her eighth anniversary. During the milestone stream, she announced a new costume reveal and a cover of the song "39" by sasakure.UK and DECO*27, scheduled for 9:00 PM that day.

- During the false alarm, Sasaki was away visiting family and could not stream. KAI-YOU reports she said the sudden jump from 990,000 to 1.02 million was "suspicious behavior" and that she could not even enjoy the afterglow of watching the theatrical film "映画ちいかわ 人魚の島のひみつ" (Chiikawa the Movie: The Secret of Mermaid Island).
- On reaching the milestone, Sasaki said "素直に嬉しいです" ("I'm honestly happy") and "みんなと迎えられてよかった" ("I'm glad I could share this with everyone").
- Denfaminicogamer published her handwritten comment: "いろ～んなことがあった中で笹木をずっと応援してくれてありがとう。" ("Thank you for supporting Sasaki through all kinds of things") and "これからも夢継続！！幸せ継続でいこっ！！" ("Let's keep the dream going and keep the happiness going").
- The same outlet notes her unit "さくゆい" with Shiina Yuika, known for their coordinated banter, and the February 22, 2025 real event "EX Gamers Event 'Odd Play-Off'" for the "EXゲーマーズ" group.
- Denfaminicogamer's press release describes her profile as a Kansai woman who loves games and aquariums, with favorite creatures being the dumbo octopus (メンダコ) and pandas.
