New anime episodes released with each of the three iDOLM@STER Shiny Festa PSP games (Honey Sound, Funky Note, and Groovy Tune).

1. Slipstream About a Luftwaffe pilot who must choose between his duty to his country: to guard a bomber loaded with Germany's final hope of victory... the world's first atomic bomb... or his duty to the world: to let it fall in flames to enemy Spitfires and be a footnote in history. Of course, things are complicated by the plane's other cargo... the woman he loves. 2. Sonic Boom Squadron Near the end of the war, Japan has implemented a new weapon -- a human-piloted rocket-propelled flying bomb. Aboard a bomber carrying one of these, young Ensign Nogami awaits his chance to die as a "cherry blossom", a suicide pilot. In a few hours, he will die. The date of his death is set: August 6, 1945. 3. Knight of the Iron Dragon Two soldiers attempt to reach an air base in order to fulfill a promise despite the fact that it might have been rendered moot in the reality of war. (Source: ANN)

Yuuta Hibiki wakes up in the room of Rikka Takarada and notices two things: he has no memories, and he can hear a mysterious voice calling his name from a nearby room. On further inspection, he finds a robot—which introduces itself as Hyper Agent Gridman—behind the screen of an old computer. Much to Yuuta's surprise, Rikka cannot hear Gridman, nor can she see the ominous monsters looming over a thick fog as it envelopes the town outside. Another giant monster materializes in the city and proceeds to wreak havoc. Amidst the confusion, Yuuta is once again drawn to the old computer and merges with Gridman. Suddenly, he appears in the middle of the battle and is forced to fight the monster. Together with Rikka and fellow classmate Shou Utsumi, Yuuta forms the "Gridman Alliance" to defeat the monsters plaguing the city and find whoever is responsible for their emergence.
