Mitsuki Ōshida

Born in Osaka in 2004, Mitsuki Ōshida is genuinely one of the youngest people I've written about on here, and honestly there's something kind of exciting about that — she's an idol who's barely out of her teens and her whole career is still being written in real time. Osaka-born idols tend to carry a certain natural warmth and sharpness that you don't really have to perform, and I'm inclined to think she's got some of that baked in. She has been with the Rino Sashihara-produced group ≒JOY since 2022 and debuted a unit song at the group's Nippon Budokan show in 2026, so she is clearly building something steady. Either way, I'm watching.
