Pixie

While they are similar in appearance to fairies, which also belong to the fairy type, unlike fairies which were originally not monsters until being corrupted by mamono mana, their nature is close to that of the succubi, and they’re genuine monsters belonging to the imp family. It is said that the souls of dead children become pixies, and perhaps for that reason, they are very fond of mischief: they lead humans who enter the forest astray.
