The game plays similarly to the core gameplay of Nintendo's Fire Emblem series of video games and combines elements of social-network games often found in mobile gaming. The game involves the player moving characters across a grid with chess-like movement requirements, and battling an opposing team of computer-controlled characters in turn-based combat. When characters take enough damage in combat, they get removed from the battlefield, with the team with remaining players being the victor. The game does not have permadeath, but characters who are defeated do lose equipped items.

In the main story, the game takes place in another world and focuses on Levaetein (later revealed as Amane in Zero's Rebellion), a mysterious girl known as a "Killer Princess". She once lived in another world until mysterious monsters attacked it, destroying civilization itself. Once she helped a man with a sword, she ventured to another world only to lose her memory and waking up in a field of flowers. When she tried to remember she gets ambushed by monsters before being helped by a Killer Princess named Tyrfing as she slew the monsters. Levaetein now must regain her memories for her true purpose while being joined by other Killer Princesses to defeat the demons plaguing the land. The prequel story game takes place in a post-apocalyptic dystopic Tokyo. 200 years ago, strange demons start appearing in the human world where humanity is under threat of extinction. Today in AD 2917, demons now roam freely and continue to destroy everything. Humanity's last hope is the Killer Project, a dangerous Super Soldier Project created by the Ragnarok Institute that would create special beings called "Killer Princes and Princesses", that can defeat said demons and wield weapons capable of destroying them. The story focuses on Zero, the first Killer Prince as he tries to resolve things in the human world, regarding the attack of the demons and the Weapons used to defeat them.

Pre-registration began for the game began in August 2014, and the game was released in Japan in late 2014. Work on an English version began right away in early 2015, but wasn't officially announced as such until June 2015. It is later revealed that the global version would be a prequel story of the game, which focuses on the first Killer Prince. The game was released in over 120 countries in May 2016. The game's Western release was rebalanced to feature more difficult gameplay. The game had a cross-over event with Brave Frontier and Dempagumi.inc in June 2016, and Puella Magi Madoka Magica in November 2019. The game's opening cinematic was overseen by Ghost in the Shell director Mamoru Oshii.
