At first glance NISA's latest IP might come off as a Persona or Caligula Effect copycat. You'll be glad to know that Monark does it's own thing though, and does it well enough. What you'll get with this latest academy oriented adventure is a dual world ordeal wherein Daemons, and the student body mesh in a conflict of Egos. Our hero of the tale, and his tag along group of academy acquaintances, each go to said academy to hone their Egos. Egos are the sum of personality traits aligned with the seven deadly sins. In this case the hero, whose Ego is tested early on via an introductory quiz from the school's dean, ends up playing into his leadership, and command role.
As a Pactbearer who made a pact with a Daemon Monark named Vanitas for a wish to protect his classmates, this protagonist who was put through the ringer, can control a small army of sin specific fiends that are summoned in the Otherworld's battlefield to fight Daemons of varying ranks including other Pactbearers. He can also wield a powerful weapon known as imagigear that acts as a soul manifested weapon specifically designed for him. The fiends which act as party members for the Pactbearer take on traits according to the seven deadly sins, and each have their own unique skills and weapons. Additionally they can equip vessels that have inherent benefits in battle. With the additional aid of other human party members who can manifest imagigear as well the party is fleshed out in full allowing the taking on of the multiple Daemons at hand. Utilizing this unique protag, companion, and fiend system is how they will come to conquer the seven other evil Pactbearers who currently have the school under barrier lockdown in a miasmic Mist that causes mind altering afflictions to the students who come in contact with it. Minding the Mist's MADdening effects, and dealing with Daemons as well as the Pactbearers is the main goal in this new chapter driven story.
