Here's my concept as an evolution for Orpheus, named Eurydice.
So I based this Eurydice off of my favorite telling of Orpheus and Eurydice which is the musical Hadestown which doubles also as a commentary on the treatment of the poor within the Industrial Revolution and Great Depression periods of America which I feel is fitting with the exploitation of children by the Kirijo Group.
In this musical, the Underworld is a mining town. Something important to know is that in the actual Underworld in Greek Mythology a good 98% of people who die go to the fields of Asphodel, where they are forced to drink from the river of Lethe and forget who they are and wander as a ghost with no identity. This is then directly translated into a soul-sucking job where you forgo your identity in the eyes of your boss. Thus, a mining town.
So because of the mining town theming I based Eurydice off more heavy machinery, I made her colors more washed out and darker like they're stained by coal dust. The metal on her parts are all rusted and worn away. I felt that really fit together with the fact that protagonist is wearing down, getting closer to the end of the story. Orpheus' original scarf is now torn up and worn like a bandana, this is a direct callback to Orpheus within the musical who wears a red bandana which fits together pretty well. There's a drachma in Eurydice's mouth because a common tradition for the dead in Ancient Greece was to put a Drachma on someone's tongue so they would have money to pay the ferryman in the afterlife.
When the Wild Card is passed to Aigis the Persona reverts to Orpheus.
