The trainees participate in a large-scale project to produce artists who will debut in Japan and go on to perform on the world stage. They share a common destiny: a mission to grow so that they can make their debut. In order to achieve this growth, the trainees will take on challenges together ("&") as they pursue their mutually shared dream of debuting ("Howling"). The trainees will have mentors by their sides. The mentors will support and evaluate the trainees as they work toward the dream together, one step at a time. After demonstrating their skills, growth, and ability to cooperate during each round, who will ultimately make their debut?
