Competitors[]
This trials special featured twelve competitors in total, representing twelve different idol groups. Similar to the previous iteration, the first eleven competitors would be announced in the livestream while the last competitor, being Kirihara Mizuki, would be announced through a post via Twitter on July 12, 2025. They would compete in various stages for a chance to compete in SASUKE 43.
All competitors competed in an event known as Beach Flags (ビーチフラッグス) that involves competitors laying down flat on their stomachs facing behind the track. Once a whistle is blown, they must stand up and run across the 25m track to grab a limited number of flags. There were a total of six rounds in this competition, which would slowly eliminate competitors one by one as the rounds progress. In the finals, the competitor who managed to grab the last flag would be the winner of the event.

Qualifying Second Stage[]
All competitors competed in an event known as Tail Impossible (テイルインポッシブル) involving competitors running around a 100-meter track for four laps, with the last three competitors finishing the laps being eliminated from the event. Competitors are allowed to rest for 60 seconds in between each race. The competitor that crosses the finish line during the final race wins the event.
An administrative error in counting the laps during Race 2 resulted in all competitors running five laps instead of four. When the fourth lap concluded, several runners halted after misinterpreting a signal that should have directed them to continue. The disruption in pacing influenced the outcome for some competitors such as Sato Rika, positioned sixth at the end of the fourth lap, was overtaken on the fifth lap and subsequently eliminated. She was later granted five points in compensation for the mistake.

Qualifying Third Stage[]
All competitors competed in an event known as Power Force (パワーフォース) involving two competitors connected to a rope on their backs, with the length of the rope being shorter than the length of the entire track. Once a signal is played, competitors must run towards a buzzer that is in opposite directions of the track. The first competitor who presses the buzzer wins the match and advances to the next rounds of the event. In this stage, winners of each group would advance to the finals and attempts to win two rounds cumulatively or consecutively in order to be crowned as the winner of the event.
