Apologies if this has already been mentioned.
Yesterday, while listening to the radio in my car, I heard a commercial for the car appraisal and purchase website "Navikuru," and I was surprised to hear what sounded exactly like Ai-chan's voice saying the lines.
I wondered if they were collaborating! I quickly looked it up and found that the voice actress for the commercial character "Nabi Kurumi" is Rie Takahashi.
It seems the commercial has been airing since April 2026.
The radio commercial and the theme song sung by Rie Takahashi are available on Navikuru's official YouTube channel.
