Makoto Yuki is a new transfer student arriving at Gekkoukan High School in the vibrant spring season. As he makes his way to the dormitory, immersed in the music from his headphones, he suddenly experiences a surreal phenomenon where time halts, and the people around him transform into eerie coffin-like shells. This unsettling event introduces him to the Dark Hour, a hidden time occurring between the minutes of midnight—a shadowy realm where dangerous creatures known as Shadows roam freely.
Soon after, Makoto is entrusted with a grave responsibility when his upperclassmen, Mitsuru and Akihiko, designate him as the leader of his fellow students Yukari and Junpei. As they navigate the challenges posed by the Dark Hour, Makoto embarks on a personal journey to understand empathy, the strength found in camaraderie, and the profound concept of death. These lessons prove crucial as the team faces increasing threats from the Shadows.
Armed with the mysterious power of the Evoker, a device aimed at his own head to summon his inner strength, Makoto confronts the menacing Shadows that seek to invade the real world. Their battles lead them to the enigmatic tower known as Tartarus, a place shrouded in mystery and darkness. Makoto's courage and leadership are tested as he fights to protect his world and uncover the secrets lurking within the Dark Hour.
