With Banagher Links as its master, the Unicorn Gundam goes into action. The mobile suit that is said to be the key to Laplace’s Box offers a glimpse of its incredible power in single combat against Marida Cruz and her Kshatriya. After the battle, the Unicorn Gundam is captured by the Londo Bell warship Nahel Argama. Also aboard the ship are Micott, Takuya, and Audrey, who have been rescued by a Londo Bell pilot named Riddhe Marcenas. Full Frontal, leader of the Neo Zeon remnants known as the Sleeves, launches an attack on the Nahel Argama with his mobile suit Sinanju in order to obtain the Box. Frontal, the so-called “second coming of Char Aznable,” claims to be a vessel embodying the hopes of the Spacenoids. What will happen when he encounters Banagher on the battlefield?
