It has potential to be something great but currently it lacks depth. The interpersonal relationships are a bit shallow, the title is "Reborn as the villainess's knight" there has been no significant development with her or what his earlier relationship was with her either. I feel like the academy arc should've been delayed a bit and his recovery and what happened to him after he was rescued should've been expanded a bit more cause tbh at this point I don't feel much connection to anybody in the story. The MC needs some personality, aspirations, flaws for us to care about him. The world building has had a lot of thought put into it and the character designs/powers are nice. This is all just my opinion tho and I hope this turns into something great.
