Took a break from Leviathan to get some less dramatic stuff... or so I thought. Ended up reading Heads. Jun, an extremely polite and weak-willed young man, has managed to do all right for himself. Sure, he's a yes-man at a cell phone company with poor products, but he's fallen in love with the freckled Megumi, a girl who shares his love of painting. His life is turned upside one day when he gets caught in the middle of a hold-up in a real estate office. When the gunman goes to shoot a little girl, Jun jumps in the way of the bullet and is shot in the head.
Several weeks pass, as Jun slowly comes back to and fades out of consciousness. At last he wakes up surrounded by doctors; he is the first adult to successfully undergo a partial brain transplant. The odds of finding a matching donor were 1 in a million, but the operation was successful. However, Jun soon starts to notice some changes - he is more assertive, more outgoing, and even at times violent. He no longer paints, doesn't enjoy movies, and most disturbingly, find himself less and less interested in Megumi. As he struggles with these changes and in tracking down his brain donor, he starts to wonder: is he Jun anymore, or is he "Donor B"?
All-in-all, it's a pretty good drama, though (spoiler alert!) not necessarily a happy one. I've always been a fan of true stories of transplant owners discovering altered tastes and preferences post-op, and this is pretty much just a logical (if fictional) extension of the premise. The manga was seinen due to violence, language, and sex (though I don't think there's ever any explicit nudity), and overall pretty good.
I also read more of Ore ga Doutei o Sutetara Shinu Ken ni Tsuite (two more chapters have come out since my last review). I really like it, but the slow release rate is killing me. I sorta wish I had discovered this series a few years from now, when it's finished, because I love the concept. It's also nice to have a harem setting where the protagonist is a player attempting to NOT get laid, as opposed to a quirky loser who managed to have all the girls fall in love with him. And that aspect is an awesome counter to the insanity/violence of knowing his best friend ends up killing him in the future.
