Disaster strikes and humanity becomes cold.
In order to survive, the scumbag of a close relative cruelly abandoned his seriously injured mother and her young child.
After being reborn, she is no longer soft-hearted and roams the wasteland with her ability to control beasts. She protects her mother and lives in peace, and counterattacks step by step.
The scumbag struggled to survive and suffered a lot. Only when he looked back did he realize that he had thrown away the treasure of his life and regretted it for the rest of his life.
