Many, many years ago, humans and dragons used to get along with each other despite the differences that existed between them in perfect harmony. However, sadly, that didn't end for too long. For unknown reason, they started a war non-stop for many years that no one can't stop it furthermore it can last till last person standing or have all race to be extinct!
Killing innocent citizens...
Building get burned down...
Lots of revolutionary standing up every time they have chance...
The taste of hate in everyone's body that will remain forever...
Till the leader of both side have finally came to decision, that they stopped the war by making a deal with conditions they choose to have in the deal.
Now after many generation been passed, the humans created a group called 'Hunter' is only for people who have amazing skills that would be useful for the organize also it's only for to kill dragons, even though they don't fight much before but they still come around and kill people for annoying things they shouldn't have done. So as along as Inazuma Town have Hunter with them on their side, all the people would be safely and protected from the dragon without any worry at all. But what if they fell in love? That would bring big trouble for human as well as dragon too, because relationship between dragon and human are forbidden, so if anyone would do that forbidden relationship then they will have to face the result for disobeying the law - part of the condition the leaders said in the deal. Can this generation change the hate into love? What will happen?
