Parasyte Review

An alien lands, burrows for a brain, misses, and ends up living in a high schooler's right hand. Iwaaki takes that premise and refuses every easy version of it. Migi is not a friend, not a demon and not a lesson. It is an organism with no capacity for sentiment that slowly develops something adjacent to curiosity, and the relationship between it and Shinichi drives all ten volumes. The horror works because the rules are fixed early and then obeyed.

Parasites reshape a face into blades, they have to eat, they cannot reliably detect each other, and every fight is won by whoever thinks faster rather than by whoever hits harder. The art is functional rather than beautiful, with stiff faces and plain backgrounds, and the transformations remain some of the most unsettling images in the medium precisely because the ordinary pages around them are so calm.

What gives the book its long critical afterlife is the argument underneath it. Shinichi loses pieces of his humanity and gains competence, and the series keeps asking whether that trade is a tragedy or simply growing up, then hands the same question to a species that eats people and finds it has no better answer. The ecological turn late in the run is blunter than everything preceding it. The ending is not. Ten volumes, no padding, and a closing stretch that earns every page it spends.
