Premise
After killing a group of heroes and destroying an entire kingdom as revenge for attacking his lands, one of the Four Beast Kings, Clevatess, takes in a baby belonging to the kingdom's royal family. He then resurrects one of the heroes, Alicia Glenfall, whom he enslaves so she can help him take care of the baby while hoping to examine humanity more closely.
Characters
One of the thirteen heroes who is killed by Clevatess, but later revived to accompany him on a journey with Luna. She is technically an animated corpse who is bound to Clevatess by his dark magic, preventing her from disobeying him or being killed.
A Demon King who rules the dark lands. He has grown interested in humanity after the heroes' failed attack. When adventuring, he disguises himself as "Klen", taking the appearance of a young boy who died while protecting Luna, though he is weaker in this form. He is not all that ruthless as he has no interest in conquest, but will attack anyone who threatens him and his lands. He is currently the caretaker of Luna and master of Alicia and Nelluru, as well as Luna's magic instructor following Dorel's defeat.
A baby who is the prince of the Haiden family, whom Clevatess, Alicia, and Nelluru take care of. Luna has a good influence on Klen as the babyâÂÂs presence is what keeps him from threatening humanity. It is later revealed that he is T'ala's son and his real name is Toth. He is soon reunited with his mother.
The unnamed ruler of Haiden, who is killed by Clevatess for launching an attack on his lands. He is later revived by Haiden's forge. After failing to convert Luna into the next heir using the forge, he drops himself into the forge as a final attempt to destroy Klen, which ends in failure.
