Anyone else half want the secret conspirator to be the other twin playing basically the same game? Because man if that wouldn't be a fun twist. Reasonably foreshadowed too (in the sense that bro clearly thinks protag would be a good leader, and we already know the whole make a fake front blahblahblah). Would need a bit more support to not just be a TWEEST, but i could dig it.
So the manga doesn't explain in detail of the consequences of gramps body overtaken by demon making his soul stays in the living realm inside his own research book like an immortal.
If monsters can hear it then use a monster to track it...

Eh... isn't that a upgrade though?
Gramps is immortal and can continue his research and at some point find some way to make a new body for himself while still being immortal and can keep knowledge about magic from being lost, which is a real worry since it has happened before.
That's the set up to turn into a God if anything.
The name of the magic item should probably be “Hamelin,” since it seems to be taking inspiration from The Pied Piper of Hamelin (even though the flute wasn’t named Hamelin, the town was).
I love the way mangaka did their art (except during Finne bizarre body pose during her introduction), it's seems closely resemble to novel's artstyle...
