This is not a Hard demon. This is a Medium at most, maybe even an Easy demon. This level took me 83 attempts, and that's like how many attempts it takes me to beat an Easy demon.
This level also has a difficulty rating of 7 on the GD Demon Ladder, while Nine Circles is rated an 11. And most tier 7 demons are Mediums.
So this might get demoted to a Medium demon.
