*Main story completed. Spin-offs and after-tales will be posted irregularly.

Junior high student Jin Hazuki was summoned to another world as a hero, but was sent back to his original world without being able to protect what was precious to him. After being sent back, as his memories faded as if they were events from a dream, only his own powerlessness and the ring he received from the princess who summoned him remained.

Three years later, Jin, now a high school student, attended the new single release commemorative handshake event for popular high school voice actress and artist Reina Sayama, who voiced the heroine of his favorite anime. When Jin's hand was held by Reina, a magic circle spread from beneath Reina's feet, and the two were summoned to another world.

The boy who was once summoned as a hero was summoned to the same world once again. —as the slave of the new hero, Reina.
