She is the number one ace killer in the world. She appears mysteriously and kills invisible people. In an accident, she was reborn as an ordinary female student. From then on, she entered the campus, started business, competed in the competitive world... And returned to the top of the world in her previous life! If someone bullies someone, he will be killed without mercy. Adapted from Mi Lan's "Reborn Group Favorite, the Boss's Vest Has Lost Again")
