Daimonas (デモナス, demonasu) are the third type of human, other than the Marked and Unmarked, in Children of the Whales. They can use thymia, like the Marked, but their ability to use thymia far exceeds theirs. They are said to be the strongest of warriors, created by the Nous.
Unlike the Marked, they can directly use their thymia on humans. They have the ability to use thymia in the presence of the Nous, and are able to destroy them. Both Shuan and Ouni also showed the ability to use black thymia.
