Momonosuke’s first photobook, Ichitōsei, now has its cover: a sea portrait shot in Okinawa. She stands in the water with wet hair, looking directly into the camera. The publisher contrasts the image with the fresher advance cuts released earlier.

Photographer Masafumi Nakayama shot the book across Okinawa. Its 96 pages move between swimwear by the sea, a cute retro-styled setup, relaxed hotel scenes, and the more revealing photographs highlighted by the publisher.

Momonosuke works in both gravure and voice acting. After winning Miss Genic 2022 and the Spring TGIF Weekly Playboy Award grand prix in 2024, she made her voice-acting debut in 2025 as Mikumo Ichinohashi in the D4DJ unit EGOEGG.
