I'm trying to write a story, can you guys help me check beginning part ?.

"Who is this guy!?" A woman screamed as she sees a dark figure flying over her head. "That's Wraith" A bystander called out. All we see is a creature wearing a white mask, his body was dark and orbited by many white long cloths, and dark smoke was all around him. People called him "Wraith". No one really knows who the hell he was. He never asked for anything but saved people's life when they're in dangers. Although he was a true hero, but people often scared of him because his skeleton mask, and his body was more like a demon than a human. He flew around the city with his "long cloths" Like Spiderman. Those cloths were more like the Egyptian mummy cloth than the normal one.
