Wait who are you again?

As they walked home they saw a hurt man on the side of the street.Arthur said who are you and the man just pointed.Arthur and Kuruma turned around to witness an explotion.The rushed to see what was happening.The just saw a tall bald man with a black leather,a black vest underneath,black glasses and black pants.He said hello children could you tell me who this is?He showed a picture of a man with long hair,brown skin and a weird head band with feathers.They said they do not know who it is and the man just responded and said useless.The man used magic and stated barading them with concrete blocks.Arthur usde his sand magic to create a wall as Kuruma lifted his up and started flying with his fire.The man then threw a sword at them flying at crazy speeds,until the man from the photo came flying in with loud explosions.He saved them,as they fell down though they met another man this time he had purple hair and was hidding.Why are you hidding they asked.You do not know who that is he own the village so do not move.The man in the black walked yp to them and said hello i am Kuros.
