The begining of the last

In the year 2300 many wars are active America against england once again, Mexico against Norway, China against Russia, Spain against France, and everywhere against Japan! It's not safe to let kids go outside anymore because there's a 99.9 chance that the child will get killed. Nasa has tried to get everybody off the earth but failed because armys demanded any parts they had that could be used in war. It seems that these wars will never end and will just keep getting men as the years gradually go on untill the earth is uterly destroyed. But there are few people who are willing to stop the wars and are risking their lives but some of them have powers that were thought to be just myths. A young girl who has powers to control elements, a teen boy who has the will to unlock his hidden swordsmen stength, a little girl who is magical, and a boy who has already unlocked his powers as the legendary warrior! And all these people live in Japan where the most danger is in all the world. But not only is humans making wars but also creatures from the demon universe who started the wars. This is not a world war but it is called a reaper war which has been going for 100 years and must be stoped before man kind as we now it is extinct. It is up to these people with amazing powers to end the reaper war and have peace on earth with no worrys.
