The sword in my hand is for important things, it can be my own life or the lives of others. The most important thing is to fight for the people I want to protect. From the moment I raise this red sword, I will fight you with the determination to die.
In a fictional simulated world, data have the same consciousness as humans. They shuttle back and forth among seven virtual worlds. The spellcasters fell in love with this world without war. They lived here and made many friends, but... The good times did not last long.
Soon... For the sake of the balance of the world, the Saint sent people to look for them, and when she was about to send them back, an accident happened. Several people who originally belonged to the peaceful world were also teleported. They crash-landed in a world called Zero Three. In this world, only swordsmanship existed, but wars continued. In order to survive, they had no choice but to embark on an adventure trip to another world. But the good time is always short-lived. The arrival of a man brings endless despair to this world. Boys and girls... Hold the sword in your hand and fight!
