"A fly youkai born of Beelzebub's eggspawn, which are actually incubators for small demons from the netherworld to obtain bodies from. It's kind of complicated to explain but they won't turn into giant monsters like Beelzebub any time soon, so that's some relief. They also don't have the ability to spread miasma like Beelzebub, so we can ignore them for now... but since we're here, we might as well make it easier on ourselves later and squish them before they get stronger."
