This is a rip off of the eminence in the shadows. basically same thing except he know there is a cult and isn't playing around the entire time. i mean same child he fixed same sister kidnapped same everything.

Yes, it's same at start but as story progress things will get different.
There aren't even 20 chapters, I should at least wait a bit before saying that "it's the same" or "is a rip off".
