From the product description, the BD/DVD will feature English subtitle.
Saint Seiya is a legendary series from the manga that was first published in 1986. This film is a reboot of the entire Sanctuary saga (first saga of the series), with new storytelling and redesigned saint armors (called Cloth).
Due to its nature, Saint Seiya is made into a fighting game from time to time. The last one was Brave Soldiers (2013), and Ultimate Cosmo (2012) before that. Seiya is also playable in J-Star Victory Vs (2014).
