In a Tokyo that exists on the far side of the screen, strong emotions give rise to Phenomenon: sealed pocket worlds that rewrite reality in the area they cover. A Phenomenon ends only when its creator is beaten or appeased. To deal with them, the military backs a special squad called Trinary, made up of Miyabi Koigasaki, Gabriela Lotaryńska and Ayami Kunimasa. When Tsubame Ouse gets trapped inside one during a concert by her favorite idol, the squad arrives in time to rescue her, and together they settle the incident. Afterward, Tsubame and another recruit, Kagura Uzuki, join the team, bringing it to five girls. The heroines draw extra strength in battle by linking with the Clan, the people who play the companion smartphone game and watch the show. As they try to juggle ordinary life with each new Phenomenon, they find that their own reality has troubles of its own. The web series mixes action, mecha, science fiction and ecchi elements.
