- This world -

After the incident happened 5 years ago, people starting to find new way to enable battle gear user to achieve immortality state without memories as the price. During the incident, many battle gear users died in order to put the demon core to sleep. Only a few left, I’m one of it, Red dragon battle gear users. There are many type of battle gears depends on your bloodline.

New generation from different bloodline emerged themselves to battle gear institution. Many new recruits coming up this year. Who am I? Ah, my name is Natsume Elzeberg, I am a veteran Battle gear users who still works there and achieved immortality state. Anyone can achieve immortality state in one condition, you have to sacrifice your precious memories, sometimes those memories will appear in your dream, but you will never be able to remember the exact event. I don’t want to talk about it….. I don’t really know why…

Working supposed to be my very last option… unfortunately, they won’t let me retire. Reason? I myself don’t have any idea why.  Perhaps because of the new invention failure, has gone wild. Our institution found out some illegal research about advancing to immortality state without exchanging memories. It wasn’t illegal at first, until abnormality shown on all the lab volunteer. At first, they achieved immortality state as we want, but in the next 1 month, they starting to lose their rationality, eventually turning to demon. We researched the problem, the demon from the experiment starts to reproducing their kind which led us into a new problem.

We all know human being are greedy, they even tried to increase tiger bloodline population by injecting the blood solution to their body to increase the population of the Tiger battle gears user, of course the resulted wasn’t what they expected. That’s why every district agree to stop all experiment against the humanity rights.
