Synopsis

Shirone awakens after seemingly dying, having experienced an interdimensional travel due to the 'Immortal Function'. He relays a message from a woman he met there to the Headmaster, who reveals that this woman, Adrias Miro, is a former disciple specializing in scale magic and an 'Unlocker' like Shirone. This interdimensional experience is described as possibly being tied to a deeper fate and the unlocking of the 'Immortal Function'. The conversation introduces the concept of 'Unlockers' and their connection to the infinite nature of space-time, setting the stage for future plot developments.
