Saint Seiya: Next Dimension

Saint Seiya: Next Dimension - The Myth of Hades (聖闘士星矢 NEXT DIMENSION 冥王神話 Seinto Seiya: Nekusuto Dimenshon - Meiō Shinwa?), also known as simply Next Dimension, is an ongoing manga written and illustrated by Masami Kurumada. It is a prequel and continuation to his manga series Saint Seiya; placed during the previous "Holy War" between the deities Hades and Athena and their respective minions, the Specters and the Saints, during the 18th century in the franchise's fictional chronology. It is published by Akita Shoten in the weekly magazine Weekly Shounen Champion at irregular dates. It is also known by its alternate subtitle Galaxy Myth (銀河神話 Ginga Shinwa?), which is used during publication to refer to the segments of the storyline set in the 20th century, as opposed to the Myth of Hades subtitle, which refers to the segments set in the 18th century.

At the release of the first collected volume (tankoubon) of the series, Next Dimension was confirmed to be canonical within the universe and chronology conceived by Kurumada for Saint Seiya.
