The overall plot and most of the character names are based on Greek myths, although as with 'Aa! Megamisama!' (1993), some of the latter can be difficult to correctly identify because of the multiple transliterations through Japanese into English. In the original myths, Poseidon fathered two children from Demeter: a horse named Arion and a nymph named Despoena (Lesfeena). While there are at least two mythological figures named Lycaon - one was the first king of Arcadia; the other was a Trojan prince - the "Lykaon" character here may instead be based on Deucalion, an analogue of the Biblical Noah, who survived a divine flood that wiped out the rest of humanity.
