On the 18th of January in year 2149 the NOA Company released the VRMMORPG Kingdom of battles. It was supposed to be a sensation, something that the world has never seen before and that was why people all over Japan wanted to get it. Natsumi Miketsukami was always an unusual girl, with really bad luck. She was never interested in normal things, she was always obsessed with video games and it was like she didn't even live a life away from her computer. And an awesome gamer like her just couldn't stay without the Kingdom of battles, the most amazing video game that was ever created. It was different from the usual video games, where the players just pressed different buttons on their keyboards. In the Kingdom of battles, a world full of weapons, magic and fights, the players actually lived the game and were able to rely only on their abilities. Natsumi was amazed when she entered the Kingdom of battles for the first time. She was interested in the completely new virtual world that was ahead of her, just waiting to be discovered. But she had no idea that something was going to come between that and start a life changing adventure.
