The S4 Selection (S4決定戦 S4 Ketteisen) is an annual competition held at Four Star Academy that determines the top four idols within each of the school's classes, and subsequently determines the line-up for S4 for the next year.


The competition takes place over a span of four days, one for each class. The students participate against their fellow idols to determine the top of their respective classes, whoever earns the highest points wins and earns a spot within S4. Points are combined from audience votes as well as scoring from a select panel of judges (the teachers and the headmaster). Should the winner be a graduating student, the runner up is appointed to become an S4 member in their place.

The first part of the Selections are unique for each class, with the second part culminating in a stage performance.

Season Two

The S4 Selection took place during Episode 98 , however, the scores were not shown.

It was announced that all four members of the 26th Generation S4 won their respective selections, confirming Yume Nijino, Ako Saotome and Mahiru Kasumi as members of the 27th Generation and marking Yuzu Nikaidō's third consecutive and final win. With Yuzu graduating, the last S4 spot fell to her runner-up, Haruka☆Ruka.

Koharu Nanakura and Lilie Shirogane were also known to have participated, and were presumably also the runner-ups of their respective classes.
