All components of physical reality are objects.
Some objects are also subjects with agency.
100% of representational art (including anime) transforms the physical reality of the world into objects to be studied — to evoke a response.
So what?
Part of the value of representational art is that it can call our attention to significant aspects of object-ness in the world — including our own object-ness.
The other side of this:
Embracing, examining, and taking charge of our existence as objects is one part of the process of liberation from others constraining us with their power and authority.
