The game is a side scrolling role-playing video game. Many journalists considered it a spiritual sequel to the Valkyrie Profile series of games also by tri-Ace.

The player follows twelve youths who are killed by an explosion in modern-day Tokyo and find themselves on the fantasy-like planet of Protolexa. There are three different endings, based on the player's actions over the course of the game, and some actions affect the game's new game plus mode.

The game was first announced in July 2015, as a collaboration between Spike Chunsoft and tri-Ace in a fourteen-page article in Weekly Famitsu. The game was developed by much of the same tri-Ace staff that had worked on the first Valkyrie Profile game, with assistance from Spike Chunsoft staff as well. Other key staff for the game include character designer Mino Taro of Konami's Love Plus series, and music composer Motoi Sakuraba, composer for tri-Ace's Valkyrie Profile and Star Ocean series. Although it was originally scheduled for release on November 26, 2015, the game was delayed to its final release date, December 17.

Shortly after the game's Japanese release, Spike Chunsoft began downloadable content collaborations with some of tri-Ace's other games, including Valkyrie Profile and Star Ocean 5 games. The collaborations, released in March 2016, consisted of character costumes based on character's from the two aforementioned titles, along with a costume to dress up as Monokuma, the primary antagonist from Spike Chunsoft's Danganronpa series of video games.

Famitsu gave both the Vita and PS4 versions of the game a 33/40 rating, with the four reviewers giving the title scores of 8/8/8/9. The game sold 37,398 copies in its opening week in Japan, with 17,414 copies sold for PlayStation 4 and 19,984 copies sold for PlayStation Vita.
