Holly Lamp has a succubus.
Succubi eat people, she knows. Witches like her and reclusive fairies are all on the diet, and even extinct humans were eaten clean by succubi.
But when she looked at Holly's horns and her golden pupils, she could always think of her seriously ill goblin friend, and she couldn't refuse to adopt such a creature.
As long as she is underage, she will not eat people... Right?
