I Broke up with Myself in the Parallel World at the Beginning

Without warning, dense cracks appeared in the blue sky like spider webs. With a bang, a gap appeared in the sky, and there was endless darkness. A figure holding a sword emerged from the darkness and descended slowly. A black robe fluttered in the wind, revealing a handsome and handsome face. The hair that had not been trimmed for a long time was tied up casually. The long sword with blood-red lines in his hand glowed with a faint scarlet light and looked extremely evil. The space was distorted, and a figure appeared in front of the young man. He was dressed in white and had short, smart hair. His face was the same as that of the young man. He also held a long sword with blood-red patterns. The difference was the look in their eyes. The black robe showed perseverance and sharpness, while the white clothes were complex and profound. "What are you doing here?" The young man in white said, looking at this "self" who looked the same as himself. "What are you doing? Of course I want to get my own things back and take action." The young man in black robe had a strong fighting spirit in his eyes. "Is it inevitable? Although I had expected this to happen one day, I really don't want things to develop like this."
