Baldr Sky "Zero"

When Edward came to in the virtual world, he was in the middle of a battle. A giant humanoid robot (simulacrum) distracted the enemy (virus) which was targeting him by yelling at him. The girl Sakura and him fought off the enemies’ attacks together and then helped out a girl who was being chased by the state army. As he was about to depart the virtual world, he remarked to Sakura that he could not remember his own name. Coming to in the real world, he found himself in a foreign room. He soon met Sakura again. She belonged to the Squall team of the Fenrir mercenary unit and this was their base. In the Southeast Asia State (SAS) where reality and the virtual world are separated, the only way to survive in this never-ending war was to pilot a simulacrum, so he volunteered to join Fenrir.
