Susumu Nakoshi is a middle-aged man who spends his days between a lavish first-class hotel and a park full of homeless people. One day, an eccentric young man approaches Nakoshi in search of subjects willing to partake in trepanation—the procedure of drilling a hole in the skull.

This mysterious person claims that Nakoshi is the perfect man for the experiment. Initially rejecting the offer, he doubles back on his decision after his car gets towed off. Nakoshi agrees to let Manabu Ito, a 22-year-old medical student, drill a hole in his skull in exchange for 700,000 yen. The procedure bears no results at first, with Nakoshi showing no abnormalities. This normalcy comes to an abrupt end, however, when Nakoshi begins seeing the homunculus in every person. With his perception distorted, how will Nakoshi face these homunculi?

An individual knows that it is not status that defines who they are, but how they perceive the world around them.

Such is the case for Nakoshi Susumu: former-salaryman turned vagrant. Homeless he may be, but he does not think or act as one normally would. Living life in the comfort of his cheap car, he is ostracized by the homeless men that he interacts with.

An intimidating young man appears before him with an offer — 700,000 yen in return for an experiment involving trepanation, the drilling of a hole in one's skull. While initially reluctant (and for good reason, one might add!), Nakoshi eventually ...

Mixed Feelings
I wouldn't call this work "pretentious" because I don't think Hideo Yamamoto is a good enough writer to be called pretentious. I would, however, call it a rambling, messy attempt at philosophising.

The art in Homunculus is fantastic, and the story is intriguing, but the manga loses itself when Yamamoto slows everything to a grinding halt to have two characters repeat lines of nonsensical dialogue to each other in an attempt at driving home some "deep" message. "We get it. We got the message 10 chapters ago. There's no need to repeat yourself." I found myself saying that (in my head) nearly every chapter.

When the manga ...

Homunculus has a very interesting synopsis but it turned out to be a big disappointment. It just botched the potential it had. At most, it was just scratching the surface. It tried to make a giant out of something small.

A lot of panels are recycled, we know the MC gets drilled in the head but why do we have to get the same treatment. It was just so messy. The whole time, it felt like the author was forcefully and repetitively drilling my skull with his psychological musings and tried to convince me it was "deep" and "smart". It wasn't, it's just bad writing

It ...
