Ok I'm not a big fan of the whole guy pulling the strings all along because it makes things so fucking convoluted
Like he made a groupe that took away powers so he can have some of the group defect so that group can find the skull thing, also the MC was part of his plan too somehow.
See how...
I really hope I'm wrong about this but all these supposed supervise harems are the same, they start off making you think it going in a new direction but then they jump into cliches, I hope this manga will surprise me
