The fourth film in the six-part Girls & Panzer: Saishuushou film series.

Eight years after the mysterious death of his father, Kaito Kuroba, a slightly mischievous but otherwise ordinary teenager, discovers a shocking secret: the Phantom Thief Kaito Kid—also known as "The Magician Under the Moonlight"—was none other than his own father. The former thief was murdered by a criminal organization seeking a mythical stone called the Pandora Gem, said to shed a tear with the passing of the Valley Comet that comes every ten thousand years. When the tear is consumed, the gem supposedly grants immortality. Vowing to bring those responsible for his father's death to justice, Kaito dons the Phantom Thief's disguise, stealing priceless jewels night after night to find the Pandora Gem before his enemies can use the power for themselves.

A parody series featuring the entire cast of The Melancholy of Haruhi Suzumiya in a smaller form factor. Among the changes are: Yuki plays eroge, Haruhi is even more obnoxiuous and loud, Mikuru is even more emotional and Koizumi harbors a deep love for Kyon. Kyon, on the other hand, is generally the same as ever.

Kakuei Kakkun Tanaka is a superhero who hangs out with his friends. In his misadventures, he becomes prime minister of Japan, visits New York and prevents a nuclear war.
