Rainy Day Serenade Anime Premieres in April 2027 and Reveals First Teaser
The Rainy Day Serenade anime has unveiled its first key visual, a teaser, and its two lead cast members, Yume Miyamoto and Takeo Otsuka. The adaptation of Haruka Kawachi's manga will premiere on Japanese television in April 2027.
The November 6, 2026 announcement expands on the adaptation, which was originally confirmed in February of the same year. The new teaser offers the first chance to hear the lead characters and shows scenes from the animation by Tezuka Productions. The production has also unveiled its first key visual, illustrated by character designer Nobuteru Yuki.
A romance between two eras
The original story is a manga by Haruka Kawachi that ran in Kodansha's Kiss magazine from November 2014 to November 2025. The series concluded with 14 collected volumes, and a side story will begin serialization in the magazine on November 25, 2026. Kawachi is also known for Natsuyuki Rendezvous, a manga that received a television anime adaptation in 2012. The protagonist is Hina Katagiri, a high school student who repeatedly dreams of an unfamiliar garden and a boy she played with as a child. One day, she finds herself in that same place and discovers that she has traveled back to 1907, during the Meiji era. There, she meets Takaaki Hongou, a young heir who mistakes her for his fiancée. The story combines romance and time travel through the encounter between characters from different eras.
