Trepanation is the procedure of drilling a hole in the skull. It is said to increase the blood circulation and improve pressure inside the skull. It is also said to bring out a person's sixth sense, the ability to use ESP, see ghosts, move objects with one's mind. This is speculative fiction based on the concept of trepanation.

i read this on a whim, i was looking for a gory horror at the time, and this happened to be under that genre on the site i was reading manga on. before i started readign i skimmed the reviews and read the word "homo" a few times and that made me excited with my yaoi addiction and what not but, once i started reading I was left with something much more than the dumb bulk yaoi-horror that i was expecting, something really deep and thought provoking!

once i started reading, I couldn't stop. I spent a whole day, reading 10+ volumes of this manga, i was completely absorbed. There's barely any gore but the tension set in this manga had me sitting at the edge of my seat a few times. While reading this manga, I was happy, angry, sometimes absolutely disgusted, it even made me teary eyed, once.

What I admire about this manga is, first, the original concept, the homunculus. I really like how the artist decided to interweave all the definitions of homunculus together in this story, the somatosensory homunculus, the fetus... etc. You can really tell he did his research and spent a long time mulling over this manga. Also, the way he did his characters, they are demented, unwhole people, and as readers (or more, human beings) we can relate to this in many cases, nobody is whole, everyone has their own shortcomings and complexes (though never as many complexes as the main character haha).

The only beef I have with this manga though is that... it was kind of hard to swallow, the whole seeing homunculi thing. part of me wanted to laugh it off, it was really hard to take seriously in the beginning, and still is (and was) hard to explain to my sister when she wanted to know just what was the hype about this manga that i kept on calling "genius, genius"

I also didn't expect to like this series as much as I do, but after reading the very first chapter, I was pleasntly surprised.

Most of what I'd like to say about this series has already been said, so I'll just let my thoughts on it rest for now. Once the entire series has finished, then I'll give it a solid rating and a thorough review.

So far so good!

Do not be put off by the twisted sex. This manga has a great premise--guy develops the ability to "see" the suppressed fears of others. Only, they are also his own suppressed fears, because hey, any Buddhist can tell you that everything, even your own personality is an illusion. Can not wait to see where this one goes. Like "Pulp Fiction" this series proves that metaphysics can be fun.

This manga is fantastic it asks who are we and why are we that way with a strange occult twist to it. Also with the help of symbolism it gets it's point across.

that`s the question this series forces through our brain? we don`t know our selves at all... but still, "who are we?"

see, that`s what this series is doing, messing with our brain, making us wonder: "if that guy is like that, then how am i like"? how is my homunculus like? the question keeps bugging me... the author does a brilliant job at playing with people`s minds... one of my top 10 favorite manga, out of 127 series read so far...

there are some "WTF?" moments scattered throughout the series, like the last volume, but it`s a brilliant series... without further ado, i hope it won`t f*ck up at the end and i give it a 9.3!

P.S: i noticed that there are no chapters, the entire volume is released as a whole... a little bit weird, but i don`t actually care, as long as i have something to read... smile

I have no clue what makes this manga a good read...most of the time it leaves me with the good old- "WTF?!" And yet, I am still looking forward to the new chapters. Read it, you'll like it.

I didn't really expect to like it that much, but I read 75 chapters in one sitting.
The characters are interesting, along with much of the plot, and it's definitely worth reading.

It wasn't very hard to follow, which was what I expected, (I usually can't get into a manga if it is.) and from all of the comments telling shoujo fans to not read this, I expected things to be much more extreme.
I could probably eat with ease while reading, so nothing's too nasty, if that's what anyone's worried about.

All in all, it's a great series, with a demented main character, and it's focus on said main character.
I would say it was a fun read, but I'm probably the only one that thinks that.
Anyway, give it a try.

All I can say is that it's addictive.

I've never really enjoyed the author's other well known manga, Ichi the Killer, because of it's sadistic nature.... But this one really hit the spot.

The protagonist is one of the best male leads ever, in my opinion, and if they ever made a movie/series out of this, they'd have a hard time finding an actor good enough (Sir Anthony Hopkins is too old, and can't speak Japanese).

Like many other psychological type series' , it does risk dragging itself too long, though, but I'll remain optimistic.

Awesome! I can't really describe it so well, but this makes things similar to ESP believable if they are extensions of your total 5 senses. I can only hope some group translates this amazing manga.

I really enjoyed this manga. Very quirky, unique, etc. ^__^ And the premise is quite brilliant. Although, volume one was a little slow but the pacing and plot picks up in the later of the series. Love the art too: it's a big improvement from Ichi where his art style was still developing.

Update: Having read the very latest volumes, I think it deserves 8.5 at best for now and nothing more as I agree with xObscurexOmen's points that Homonculus is brilliant, innovative but a little flawed for now. It remains to be seen how the plot/story will move along. But at least, it's quite an improvement from Ichi the killer where things were quite interesting but fizzled out a little towards the end, for me.
