Demons are beings whose appearance and ability vary between one and another, but what they all share in common are the ability to use powerful magic (including forbidden Time Magic) and inherent malevolent nature compared to regular magical creatures and prospect of them being natives of hell, a place where souls of the damned would go. They also have a significant influence on human culture, as it was known that demons tempted many mortals to make a pact with them in exchange of their wishes (be it power, status, etc.) granted and their body parts (ex. horn) can be used as ingredients for enchantments. However, due to the demons' own treacherous nature and harm from establishing a pact with them (wishes granted from the said pact always come with a price which including one's life), witches eventually became wary toward them and deemed them untrustworhy. Although, this doesn't deter some witches from willingly made a pact with these creatures out of either selfish or malicious reasons.
Croix's lecture in "Chariot of Fire" includes illustrations of past mystical practices with darker reputation where some of them involved demons, implying that these foul creatures were partly responsible in causing mundane humans to be wary of magic and its practitioners throughout Middle Ages and subsequently, being among catalysts Witch Hunts.

—Description of Demon Horn from Strange Notebook
Demon Horn is one of usable materials for enchantment in Little Witch Academia: Chamber of Time. True to its description, it is a broken piece of horn belonged to a demon, arguably a Baphomet Goat judging from its shape and coloration. Thanks to small yet substantial amount of demonic power within signified by ominous aura it constantly emanates, the horn can be used as enchantment material. For the same reason, Demon Horn can plausibly serve as alternative in attaining demonic power thus terminating the need of establishing a pact with a demon.
