Unaging

While changing clothes, Lumian examined the changes in himself after becoming a Demoness of Unaging.

Because of the reconciliation, his Mirror Person's consciousness had returned to his body. Whether it was his reflection in the mirror or himself outside it, they were now both him—different parts sharing a single consciousness.

In other words, he had the sensation of being both outside and within the mirror simultaneously. Even walking in sunlight, he would partially experience another self moving hesitantly forward in darkness.

This also allowed him to see both the reality and the changes within mirrors simultaneously.

Furthermore, in the past, when a Mirror Person died, it would split off from the body again to revive. Now, the body had the same privilege—if it died, it would revive through the Mirror Person.
