In Kizumonogatari Part 1: Tekketsu, consciousness is carried by monsters and creatures — a plane of “vampire underworld”. The story fights on E8/E9 of the E0–E14 reality ladder, compressing identity, mortality, power, otherness.
Films fighting at the same level of reality, about the same things.
The same preoccupations examined at another scale — one mind versus a nation.
Other films that move a human interior onto the same kind of thing.
