Hobi hobi no me,
arguably the most OP thing in existence if used right.
so the jist is that anyone you touch is,
turned into a toy that you can fully control and they can never resist at all,
every memory of their ENTIRE existence is removed, the person never existed,
physical records are not removed though so you gotta be careful of that,
you also physically no longer age, yes you read that right.
basically by using this you can remove people from society that nobody will ever miss to
create a slave army of workers, toys do not age either btw, they will work until they crumble
to dust,
all the while using your agelessness and free labor to admass an empire over the years.
