The Dark Assassin
The episode begins with a display of Kamiya Craft's newest LBX, Assassin, and its sniping capabilities. Yoshimitsu Kaidou, Tougorou Kamiya, and Muneto Sawamura are all pleased by the results of the small exhibition. They expect Jackal, the assassin, to perform his task without any trouble and kill the Prime Minister. Elsewhere, Takuya and Ren converse about the assassination attempt on Prime Minister Sousuke Zaisen. They decide to ask Ban, Ami, and Kazu for their assistance. Before they talk about the details of the mission, Kazu is given a new LBX, Hunter, sparking a glimmer of interest in his eyes. Ban and friends accept the mission, agreeing to the terms of it being a secret and that no one must find out about it. The next day, the trio show up to perform their task, but Kazu doesn't seem to be ready or in the right state of mind.

LBX: Little Battlers eXperience
In 2046, a revolutionary 80% shock-absorbing reinforced cardboard has been developed, rapidly transforming the world's exports. The reinforced cardboard would soon become the battleground for a popular children's hobby called "LBX" (Little Battler eXperience).
Four years later, a boy named Yamano Ban who loves to play with LBX (although without a mecha himself) is given a case containing the model AX-00 by a mysterious woman. He is told that he now holds the hopes and despairs of mankind in his hands.
