Encyclopedia Entry:
A mutational variant of imp possessing vast demonic energy on her tiny body. Besides imps who mutated after storing up demonic energy due to frequent sex, there are those who were born as arch imps due to having powerful sorcerers or heroes as fathers. Their appearance is exactly the same as an imp, but the coloring of their wings and tail are paler, and of their hair is dyed white. It’s a distinguishing trait that can be seen in the demon lord and her daughters. It’s regarded as an expression that they possess lots of the demon lord’s demonic energy, and are closer to her than even among her own kin, the Inma. As inma, they possess vastly greater power than higher rank demons such as succubus, etc. They weild powerful charm spells and have excellent sexual techniques. However, they’re only around as intelligent as the normal imp, so they’re childish and simple, and they assault human men whenever the desire should arise. Additionally, many of them don’t even realize that they’re arch imps, and live among groups of imps.
Men afflicted with their charm spells start to find them unbearably cute, so cute that they want to spoil them. In that state, the men can hardly refuse when they “beg” for indecent acts, and most end up having sex with them just the way they want. In actuality, these charm spells are released unconsciously whenever they tempt a man, so they aren’t aware that they’re using magic themselves, and to them, “a nice man who will listen to whatever they ask, and do lots of stuff that feels good” is extremely attractive. They’ll probably end up liking him in no time at all. The things they beg for from men they like end up becoming increasingly lewd. By having sex with one of the highest ranked inma a countless number of times, men will end up becoming their prisoners from the bottom of their hearts.
Furthermore, imps are often used as sorcerer’s familiars, but when a sorcerer summons an imp, an arch imp may rarely appear. If he thinks it’s an imp, and binds a master-servant contract, then at that point in time, a master-servant reversal will occur, and conversely, the sorcerer will end up becoming her familiar.
