Kotoko Sasaki, a former member of Nogizaka46 and active voice actress, announced on her SNS that she will be leaving her agency, Style Cube, as of June 30, 2025.

Sasaki wrote, "I extend my heartfelt gratitude to everyone who has supported me thus far. I will redouble my efforts and would be grateful for your continued support. I look forward to your ongoing encouragement," expressing her thanks to fans and showing strong determination for her future activities.

This sudden announcement prompted numerous comments of surprise and support on social media. Comments included "Kotoko left Style Cube?" and "It's so surprising, given it was the agency of her admired Kaori (Ishihara Kaori)," as well as speculation about her future base and direction, such as "Where will she go?" and "Perhaps she found something she wants to pursue, even if it means changing agencies." The topic garnered significant attention, with "Style Cube" quickly rising to the top of Yahoo! Search's trending words immediately after the announcement.
