Persona 3 the Movie: #1 Spring of Birth

At midnight, a hidden hour known as the Dark Hour emerges—an hour most people are oblivious to. Those who aren't trapped in coffins during this time, and who find themselves awake, face dangerous creatures called Shadows. However, a select few have the ability to wield Persona, a unique power used to combat these threats. This group, known as SEES (Specialized Extracurricular Execution Squad), is dedicated to discovering the cause of the Dark Hour's existence. Shortly after transfer student Makoto Yuuki arrives at Iwatodai Dorm, his Persona awakens following an attack by a powerful Shadow. He is soon recruited into SEES, where he joins his teammates in the battle against Shadows, striving to protect humanity and understand the mystery of the Dark Hour.
