Alex was feeling extremely relieved as he was able to get to Rachel's side in time to stop the blade of the enemy from taking her life. Alex then looked at the surrounding people. It would seem that they do have a lot of people on their side. Still it wasn't a problem for him to deal with this much. Since it look like they were just numbers with no quality.
First off Alex quickly dealt wit the man that was about to stab Rachel. Using his sword that was as long as a longsword, and shaped like a katana. He knew that Rachel was watching so he couldn't kill the man, so he stabbed the man's legs instead, making him unable to move. The man who was stabbed couldn't react at all, since Alex moved without showing any signs that he was going to attack.
Alex then proceeded to attack all the enemies near Rachel. With his inhuman speed and reflexes Alex was able to beat them with ease. He subdued the enemies by stabbing their legs, breaking their arms, or just doing both.
