Akihito helps Mirai defeat one of her very first youmu! He tries to use this as his chance to become closer, but instead Mirai seems to be pushing him away! Why won’t his bespectacled beauty join the Literary Club?

Mirai isn't allowed to hunt youmu for one month as punishment for going near the Hollow Shadow. Now she must get a part-time job to pay the bills. As Mirai comes out of her shell, perhaps she will heal the hearts of those around her...

Akihito is beside himself when he learns that Mirai has vanished. It doesn’t help that something in town seems off, either. Akihito keeps hearing a strange sound coming from the sky that no one else can hear. Could something be up there?

This episode takes place two years prior to the anime series and begins when Hiroomi receives a request for a job from his older sister Izumi: to subdue the invulnerable half-yōmu Akihito. Hiroomi's younger sister, Mitsuki, encounters a dark silhouette in the street on her way to follow Akihito and her brother.
