The countdown to extinction begins on Sunday with the arrival of the Septentriones, otherworldly invaders set on the eradication of mankind. Caught in the crossfire, Hibiki Kuze and his friends join in the war for humanity's survival by signing contracts with demons to become "Devil Summoners." Soon, their abilities attract the attention of JP's, an underground agency led by Yamato Houtsuin. Once recruited into JP's, Hibiki and his friends fight and bond alongside other ordinary citizens who are Devil Summoners. However, with each new day, another Septentrione appears to wreak havoc upon Japan. Even if many lives are lost in the process, before that night ends, the young summoners must defeat the invaders at all costs.

At the stroke of midnight, the Dark Hour appears—a secret hour which most are unaware of. Those not trapped in coffins during this time, unfortunate enough to find themselves conscious, are met by dangerous creatures known as Shadows. A select few, however, possess the potential to wield Persona: a special power used to defeat these beings. This secret group is called SEES (Specialized Extracurricular Execution Squad), and their mission is to uncover the reason behind the Dark Hour's appearance. Only a short while after transfer student Makoto Yuuki begins his residency at Iwatodai Dorm, his Persona awakens after an attack by a strong Shadow. Now recruited into the ranks of SEES, he begins fighting alongside his comrades, as only they can protect humanity from Shadows and prevent the anomaly that is the Dark Hour.
