People should really read up on the story of Eros and Psyche if they want to have an insight into how Cari is borrowing from the Greek mythos. Anima means "soul", soul in Greek is Psyche, Psyche was a mortal woman whom fell in love with Eros (cupid), one aspect of the story sees her open a box containing a death-like sleep of which she is awakened from by Eros. There's a bunch of other things like this in the story, such as Ogygia being the server where you find Calypso and the Island of Ogygia being the home of the nymph Calypso, daughter of the Titan, Atlas. Hell, even Caribds' name is a modification of Charybdis the Greek sea monster.
