I've seen rape as a plot device before. I don't have much of a problem with it but I usually stay way from genres that tend to have it. But imagine my surprise when it somehow found its way into my generic fighting comic and in one of the most blatant and mishandled ways I've ever seen.
The author literally introduced her, showed that she cared for and loved the MC, then had her raped so the MC can have a reason to want to learn to fight. And that's it, it turns back into a generic fighting manga like nothing ever happened. The rape victim, who was suicidal, is put aside so the MC can develop his special eyes but occasionally shows up in flashbacks so the author can show how HER rape affected HIM. All within the first 5 chapters. It'd be laughable if it wasn't so messed up.
There are plenty of other plot problems besides this too. There's a teenager fighting competition that was created to reduce teen related street and school violence, yet most of the acts of violence I've seen so far has been in those exact places and very publicly.
Every other character has no real motivation to fight and be violent except that they love it. Our MC is the only one that was so special that someone else had to be violated for him to want to fight.
Every bystander is as spineless as the MC was before he got his "motivation", so no one tries to help people that are being assaulted. They won't even call the police(Which, after all this bull, I'm not even sure exists in this world).
Even with the rape, this is as generic and cliched as these types of stories come, just with a bit more blood and mature themes. Which isn't so bad, it's why I like these types of stories in the first place. There's just something strangely entertaining about teenage dudes fighting each other like it's the most important thing in the world. The action scenes are over the top and ridiculous, just the way I like it. And as a bonus, BOTH the men and women are nicely drawn.
Maybe the author wanted to be deep and have an MC that's motivated by something other than the usual "I want to be the strongest!" affair or maybe he just doesn't think much of rape. Heck, maybe he has some awesome character development plans for the future. All I know is, if you ignore certain things, it's not the worst fighting manga out there.
tl;dr Read chapters 1&2, skip 3-5, then continue onward. It'll save you a lot of face palming.
