I've heard of this setting.  Isn't Oratio your standard Etrian Odyssey type dungeon rpg as a Light Novel but with a Shonen protag who's got potential romance sim options out the wazoo, the Gods Exist and at least two of them want the protag because of his pure innocent soul (innocent even when he's drenched in the blood of his monster enemies)?

...
Don't get me wrong: I'm still interested.  I'm just kind of confused.
