A new Saint Seiya spin-off was released during the Complete Works of Saint Seiya event that is happening in Japan. Saint Seiya Golden Age is a 132 pages light novel in which the Bronze Saints fight the goddess of innocence and justice Astraea.
The light novel is a single edition containing 31 illustrated pages and 90 pages of text (much like the 2002 light novel Gigantomachia).
Saint Seiya Golden Age is also a collaboration between several people that have worked on other Saint Seiya spin-offs. The story is by Megamu Okada (Episode G Assassin) and illustrations by Chimaki Kuori (Saintia Sho), Shiori Teshirogi (Lost Canvas) and Yun Kouga (Hero of Heroes).
