Meet Eiji Bando, a deranged, hentai manga-reading psychopath with a penchant for gunning people down. As a hitman, he works for the yakuza, causing plenty of collateral damage wherever he goes. Whether he’s joking about violating his male peers or just blowing people to bits, Eiji Bando always has plenty of disturbing fun in the process!
Out of these three basically standalone chapters, the third one is the best. Possibly because it actually fleshes out a concept and doesn't just create a scenario for a massacre. It's pretty funny seeing Bando and the stalker getting along with each other while they try to convince a high school boy to not kill femself--at least not until they've had the opportunity to rape fem. As for the first two chapters, they portray Bando bursting into crowds of armed people with feir guns ablaze, killing everyone with ease while singing songs. Fe's so good at shooting that fe can accurately hit people behind feir back without even aiming. These types of mass murder scenes can be exciting if done right, but without a proper buildup of tension it isn't really captivating. There is a bit of a discrepancy I thought I'd point out in that in the first two chapters, Bando gets pissed when people call fem a hitman or assassin--saying that fe's a gunman, a gunman!--but then in the third chapter fe introduces femself as a hitman. The art includes background doodles and sloppily drawn characters alongside the mediocrely drawn characters. With little flourishes and abstractions thrown in.
Edited at 18/03/2016 If you ever heard about Gunmania, it's probably because you heard about the author elsewhere: after all, this is a short manga written by Kouta Hirano, the guy who is known mainly for his works Hellsing and, more recently, Drifters. I haven't read Drifters yet, but I'm familiar with Hellsing, and his style in Hellsing seems to be the same as in Gunmania... kinda. The "story", for what it's worth, isn't a coherent plot but rather something like 3 "one shots" with the same main character: Eiji Bando, a crazy guy who calls himself a gunman because he kills people with his guns. While we're served some kind of excuse for this guy to just kill people in the first 2 chapters (with all the gore you'd ever need - this guy wrote Hellsing after all), the 3rd chapter is just comedy. Well, not that it made me laugh though, rape-jokes get stale very fast imo. Add some very classy dialogue to the mix of gore and rape-jokes, with memorable lines like "Don't make me ass-rape you to death you homo bastard", and you know you're gonna get an instant classic. Characters aren't especially noteworthy either, since only one of them appears in more than 1 chapter and most are killed before we even learn their names. The MC looks like a prototype of Alucard, not only physical appearance but also in how he's just a crazy guy with big guns. The art had some good moments, but is mostly mediocre or just bad. Some poses will be recognised by those who know Hellsing. Overall: it looks like Mr. Hirano really wanted to draw some manga to experiment in, and so this little turd got published. I definitely recommend looking for something else, unless you're hell-bent on finishing everything that has the name "Kouta Hirano" on it.
Surely, this is manga by famous Hellsing author - Kouta Hirano. Story - Well, this was something chaotic. Most of the time I didn't understood about what most chapters are because there was only violence (in Alucard style, lol) and some gay jokes. Yeah, I laughted one time or two, but that's it. Maybe it's just because I'm not very fond of gay jokes. Art - All, who read Hellsing, can recognise the style, it's same as Hellsing art. I mean face angles, shooting angles, blood, gore and etc. Characters - Well, main hitman is something different from what I expected, and he dissapointed me very much. He was lame, lazy and homosexual (I think, I'm not sure). I guess it's for author to decide, but I didn't liked it. Overall - It's a funny manga to blow ones mind and to relax, but don't expect anything much from it, because your going to be dissapointed.
