Manga Origins and Time-Slip Premise

Created by manga author Haruka Kawachi, Namidaame to Serenade (Rainy Day Serenade) originally began serialization in Kodansha’s shōjo manga magazine Kiss in November 2014. The series concluded its run in November 2025 after spanning 14 collected volumes.

The narrative blends romance, mystery, and historical drama:

• The Protagonist: Hina is a modern student who, on rainy days, experiences recurring dreams of a younger version of herself playing in an unfamiliar garden alongside a mysterious boy.
• The Discovery: When Hina happens to stumble upon this exact location in real life, she encounters Takaaki, who immediately mistakes her for his fiancée, Hinako.
• The Twist: Takaaki takes her to what he believes is Hinako’s residence, where Hina comes face to face with a girl who looks identical to her. She soon realizes the impossible truth: she has slipped backward through time from present-day Tokyo to Japan in 1907, during the Meiji era.

Creator Haruka Kawachi is well-regarded for mature romance storytelling in the anime community, having previously penned Natsuyuki Rendezvous, which inspired an 11-episode anime adaptation by studio Doga Kobo that aired from July to September 2012.
