Junk: Record of the Last Hero is awful. I've only read the first volume, but I can just tell. I must insist no one else read it, even though I know this is a completely unobscure series that millions are just clamoring to get their hands on.
The main character is utterly unlikable. Not because he's the bad guy, I have no problem with that as shown by my massive love for the series Death Note - Light is basically an egomaniacal genius with a god-complex, but he's still likable on some level, or at least interesting. But Hiro, the antagonist here, is just a boring, selfish moron. He has no real reason to use the power he's granted by this special suit he receives in the mail. He claims to be a god, but doesn't do anything but beat people up and destroy things, whilst being really emo.
Did I mention he's a moron? He goes to an autograph signing of his favorite singer, gets to meet her and all, but doesn't actually get her signature because their session is interrupted in the middle by her security due to some ruckus happening outside the building. The ever brilliant Hiro thinks to himself 'Oh snap! I shall get my autograph no matter what,' puts his suit on, and heads out with the intention of making his idol feel safe enough to continue with her special appearance. Naturally, the only real solution is to knock signs off the top of buildings into the intersection where the crazy man is, because obviously a knife-wielding drug addict threatening to kill himself is way more dangerous than a dude in a costume causing mass destruction to the area.
His only friend is his cousin, who basically looks like him with long hair, which makes the fact that he pretty much tries to rape her even more disturbing. Oh, and she's stupid, too. Something happens that makes it so her parents invite him to stay at their house for a while, all after the near-molestation, and she basically says to him 'I know you tried to force yourself on me, but I'm totally cool with that, because you're in a bad situation now. And it's okay that you'll now be living in my house, it won't be awkward or scary for me at all.'
The dialogue is repetitive, with a cop that has to get in something along the lines of "I WILL ARREST YOU!" every time he appears. Perhaps it's the translation, but at times the characters' thoughts and speeches make very little sense. Hiro's aunt makes him breakfast, and when he finishes, he says "Thanks for the food," and his aunt's thought bubble says "Well, he's blunt." What?
This manga is just a really hot mess, and is best avoided. Unless you do it for the lulz.
