Galen was already out on the field due to his fight with Minny, but he was able to quickly grasp the situation, and when he looked around, he decided to help his mother. He could see where she was struggling and why she was struggling.
With that, he had jumped up and used his shadow powers to stop the attack from hitting the crowd. Now that he was able to help his mother, she could focus on killing the Divine creatures.
"What about Minny?" Layla wondered.
"Minny is strong, you don't have to worry about her, kill this monster then save her!" Galen shouted.
Never did Layla think that she would be taking advice from her own son, yet here she was. The creature that was on the floor was hurt. Although they had strong attacks, it looked like their bodies weren't particularly hard.
