did i write something wrong to not get reply?
I didn't understand questions 2-3 enough to attempt to reply
Question one, no he's obviously not the most powerful otherwise why would he be following Lilith's command about the contract. There's plenty of supernatural creatures more powerful than MC is right now.
Question four, not something I would say yes or no to because if that was gonna happen, why would I dampen that story beat by revealing it early? Any major story elements can be assumed that we will not discuss them publicly to preserve the experience for the audience
