This song is the first song I have ever had sung by the duo of Teto Kasane and Una Otomachi. Teto's strength and Una's absolute brightness match each other, creating an immense driving force for the song. The song was created with a nautical theme to express the idea of overcoming even the rough seas by one's own strength against the unreasonableness of today's world and the blurring of things that are not going well. We hope you enjoy the best duo of Red and Blue! Translated with DeepL.com (free version)
