The series had 4 million copies in circulation by September 2025.^[7]

The series was ranked fifth for the Tsutaya Comic Award.^[34] The series also ranked ninth in the 2024 edition of Takarajimasha's Kono Manga ga Sugoi! guidebook for the best manga for female readers.^[35] The series won the grand prize at NTT Solmare's Digital Comic Awards in 2024.^[36] The series was ranked first in the Nationwide Bookstore Employees' Recommended Comics list of 2024.^[37] The series was also nominated for the 48th Kodansha Manga Award in the shōjo category.^[38] The series was ranked tenth in the web category for the 2024 Next Manga Awards.^[39] The series was ranked third in AnimeJapan's "Manga We Want to See Animated" poll in 2025.^[40] The series was nominated for the 71st Shogakukan Manga Award.^[41]

Reception to the manga's ending has been the most controversial aspect of the series. Following the release of Chapter 79, the series' main story concluded on January 26, 2026, in Japan.^[42] Many readers and reviewers found the finale disappointing and illogical, and it was poorly received by both Japanese and English-speaking audiences. Common criticism included the unrealistic depiction of Satoko's survival despite her terminal illness in the Meiji era, a sudden timeskip, an unexplained decades-long separation between the two protagonists, and what many perceived as contrived resolutions to key narrative conflicts.^[43]
