Matsuda previously wrote the Shōsetsu Nanatsu no Taizai -Gaiden- Sekijitsu no Ōto Nanatsu no Negai novel, which shipped in December 2014, and Kodansha lists that The Seven Deadly Sins: The Seven Scars Left Behind is a sequel of that novel.
Manga and light novel publisher Vertical announced at its panel at Otakon on Saturday that it will release Shuka Matsuda’s The Seven Deadly Sins: The Seven Scars Left Behind (Shōsetsu Nanatsu no Taizai -Gaiden- Karera ga Nokoshita Nanatsu no Kizuato) novel.
Matsuda wrote the novel, and original The Seven Deadly Sins manga creator Nakaba Suzuki provided the illustrations.
The novel is a story that ties together the time from after the tragedy until the Seven Deadly Sins return to Liones.
