The first appearance of vigilante of darkness

It has been two weeks since James-san and Alfred-san has returned home, in this two week he has created a cave under his manor, he put a big computer with some devices in there he has created a car which he named ''Dark car'' and a flying vehicle which he named ''Dark wing''. He wanted to start his work, he opened a chamber and take out a dark suit from it and wore it, it was completely dark black, then he put a mask on his face which covered his face completely and had two blue shining eyes, then he put on a dark cape which also had a dark hood and he then put on the hood. Then he turned on the dark wing and rided it and went out, he jumped out of the dark wing and landed on a building, then he take a look at city. The city was in peace or it seemed, in one street, 5 young street drifters were bulling a family to give them anything valuable. He went into the street and told them to stop it, they turned around, one of them said: (Who are you?) He said: Ore Omae ra (I am dark nightmare and I am here to stop you.) They laughed, one of them approached him and told: Omae (I don't know who you are, but if you don't want to get into trouble, I advise you not to get involved.) Dark-san punched him in gut which caused him to spray blood from mouth and then collapsed, which shocked others, the rest of them attacked him but he with use of his physical power and martial arts techniques defeated all of them. After that he tied them and called the police, then he told the family: The police are on they way, wait here and explain everything to them. Then he left. He went toward a tall building that he know criminals were in it. He went inside and then a light went on. Some criminals appeared. One of them said: Omae (Who are you and what are you doing here?) Dark-san said: Ore (Let's just say I am here to beat you.) Then he jumped and hit a criminal. The others attacked him. One of them attacked with a whip. Dark-san dodged the whip attacks. Then another one attacked with a sword. Dark-san catched the whip with his right hand and then used his bare left hand to catch the sword. Then he pulled them together and hit them with his hands. Then he jumped on one of criminals head and pushed him down and then he throw a kick to another criminal. Then he used a powerful punch that he hit a criminal and that criminal got thrown and hit another 2 criminals. Then he tied all of them and called the police and left. This was how James-san started his work as a crime-fighter.
