Lempo, the Love Demon

Notes:

"Lempo is a sort of fiend from Finnish folklore and mythology. Lempo is the god of love and fertility in Finnish mythology.
After Christianity came to Finland, the reputation of Lempo worsened: it is portrayed in the folklore usually as an erratic spirit, as love can be capricious, even dangerous, and it could even take control of a being and turn them to destruction."
– Wikipedia

TL:DR; Lempo was formerly a Love guru, now she's the "Love" demon
(Also this really old artwork, like a year old lol)
