I've seen people mistaking Shinki for the goddess of hell. I assume that this misconception stems from this passage on the wiki?
"Due to her angelic and demonic elements, Shinki is sometimes considered to be a fallen angel, in particular an analogue to Lucifer or Satan (who was described as bright and beautiful, matching Shinki's name). Pand?monium, the capital of Makai, was the capital of Hell in Paradise Lost."
Saw someone said Shinki is no longer the goddess there because of Hecatia...
