The official website for Kodansha's Shōnen Magazine Edge announced that a manga adaptation of Mamoru Iwasa's Nanatsu no Taizai: Seven Days (The Seven Deadly Sins: Seven Days) spinoff novel will begin in the magazine's February issue on January 17, 2017. The manga, Nanatsu no Taizai: Seven Days ~Tōzoku to Seishōjo~ (The Seven Deadly Sins: Seven Days ~The Thief and the Holy Girl~), will adorn the cover and have a color opening page.

The novel is a spinoff of Nakaba Suzuki's The Seven Deadly Sins (Nanatsu no Taizai) manga, and tells the story of how Ban and Elaine met in more detail. The Shōnen Magazine Edge website describes the story:

In the land north of Britannia, there is a forest where humans are not allowed to go, and it is known as the "Fairy King's Forest." The one known as the Fairy King, Harlequin, has not been seen for 700 years. His younger sister Elaine guards the Fountain of Youth from human greed by herself. After many partings and 700 years of isolation, her tears are about to dry up. Then, a young man appears seeking the Fountain of Youth. That young man's name is Ban. Over the course of seven days with Ban, Elaine's heart is healed. The distance between them closes, but...

Yō Kokikuji ( Doutei Jigoku ) is drawing the manga adaptation.

Kodansha published the spinoff novel on October 17. Kodansha has also published three "side story" novels by Shuka Matsuda, and Vertical will release Matsuda's The Seven Deadly Sins: The Seven Scars Left Behind (Shōsetsu Nanatsu no Taizai -Gaiden- Karera ga Nokoshita Nanatsu no Kizuato) novel in North America.

Suzuki launched the original manga in Weekly Shonen Magazine in 2012, and Kodansha published the 24th compiled book volume on December 16. Kodansha Comics published the first English volume in 2014, and the 16th volume shipped in September. Crunchyroll is posting the new chapters as they appear in Japan. The manga is currently on hiatus until January 18, but some of Suzuki's side stories will run in the mean time.

Suzuki drew two spinoff manga for The Seven Deadly Sins in February 2015. Chiemi Sakamoto debuted the Nanatsu no Taizai Production (The Seven Deadly Sins Production) comedy spinoff manga last November. Jūichi Tamaki's Mayoe! Nanatsu no Taizai Gakuen! comedy spinoff manga began in 2014 and ended in November. The series also had a crossover chapter with Fairy Tail in 2013.

The original series inspired two television anime, and the manga's compiled volumes have bundled two OVAs.
