Masami Okui is set to release her first single in nearly eight years under the Lantis label. The single, titled Baby Baby Baby, will be available on April 23, 2025. This marks a highly anticipated return for the veteran singer, with the lead track being her first collaboration with Bonjour Suzuki. The song has been selected as the opening theme for the upcoming TV anime Please Put Them On, Takamine-san, which is set to premiere in April.

The single promises to highlight the synergy between Okui's powerful vocals and Bonjour Suzuki’s playful, coquettish singing style, creating a perfect balance of sound. The coupling track, an original composition by R・O・N, showcases a cooler side of Okui, offering a striking contrast to the upbeat lead track.

The single will be available in two editions: a limited first-edition 8 cm single featuring exclusive Please Put Them On, Takamine-san artwork and a new photo of Masami Okui, evoking the charm of classic releases, and a standard 12 cm edition. This release is designed to be enjoyed not just for its music but also as a collectible physical product.
