That would just empower the devil. Devils become stronger the more people fear them so it's not possible for a devil to spawn from the fear of another devil. But this is Fujimoto we are talking about so I don't know.
Maximum with the top tier devil
Not really it just make the devil more powerful
Devil Devil lol
Who knows. While reading this post i started to think about Human devil. Would be interesting to see it
That'd just be Mahito from Jujutsu Kaisen.
