Shiori has been appointed as an ambassador for a skincare brand

Shiori of MCZ appeared at a commemorative talk event in Tokyo celebrating her appointment as an ambassador for the skincare brand iYON.

iYON is a skincare brand developed by Nippon Television Retail Business Department acting as a manufacturer. It was launched in January 2025 through a collaboration with 4MEEE and is described as a beauty brand that creates a happy version of myself.

The MC of the appointment event was Nippon Television announcer Kokoro Nukariya. In fact, Shiori and Kokoro are known to be childhood friends who have known each other since kindergarten. This was their first time appearing together professionally, and Shiori shared the following heartfelt comment.

"I have always hoped that we could work together someday ever since Kokoro became an announcer, so I am really happy."

After the event, iYON image videos featuring Shiori, along with making-of footage, have been released one after another on YouTube.
