Rance VI -The Collapse of Zeth- (Rance VI -ゼス崩壊-) is the ninth installment of the Rance Series, released in August 27th 2004 in Japan. A new uncensored version translated in English and bundled with Rance 5D was also released by MangaGamer on the 23rd December 2016.
Despite the fact that 5D was released earlier, Rance VI is usually considered the beginning of the new Rance timeline set after Kichikuou Rance, due to the much bigger scale of the game along with the fact that it takes place in LP0004, leaving the year LP0003 where Kichikuou Rance would have taken place as "the missing year", since the canonical events of that year weren't adapted into games. It was also from this point that many details of the lore and the setting were better established and given further detail.
