Little Battlers eXperience

Humanity had invented fortified cardboard in the year 2046.The fortified cardboard had revolutionized the world market. It also served a greater purpose for reviving the cancelled distribution of the miniature hobby, Little Battlers Experience (LBXs). 3 years later,the story focuses on Ban Yamano who was LBX battling alongside his best friends, Kazuya Aoshima and Ami Kawamura in the 2050 LBXs World Tournament,Artemis .The episode goes back in time before the event, when Ban was on his way to the Kitajima Model Shop.There, he saw a rare, unscheduled released armor frame kit, Achilles. Despite his low allowance and his mother's objections against LBX, Ban wanted the kit very much. Before going home, Ban comes across a mysterious woman chased by 3 unknown pursuers. The woman gives Ban a mysterious metal suitcase without any instructions. It is later revealed to contain an LBX model, AX-00.

After a recap of the first episode's events, Ban wakes up in his room and looks at AX-00 and a flashback occurs to when the mysterious woman gave him the suitcase. He then is seen eating breakfast and, expecting his mom to disapprove of his new LBX, he was surprised when she said that he was allowed to keep it so long as he becomes "strong" and doesn't lose to anyone. Ban then goes to the Kitajima Model Shop and is surprised that the store's owner, Kojirou, has never seen a model like AX-00 before. After conversing about how Ban got his hands on the model, the episode switches to the Innovator's hideout where Dr. Yamano talks to Eiji Yagami about the deathlock system-if anyone but the intended user of the LBX tries to open it, a poison will be dispersed, killing the infiltrator and destroying the hidden data. Thus, Eiji decides that he will defeat Ban and retrieve the data. Back in the model shop, the group discusses how they should handle the AX-00 information.

Ban is challenged by Gouda to an LBX battle. In order to make it "fair", Gouda lets him use the Achilles armor and confidently tells Ami and Kazu that they can battle against him as well as a handicap. Seeing that they have no other choice, Ban accepts his challenge in order to protect Achilles. It is also revealed that Gouda is doing this under someone else's bequest. While the trio are preparing for the battle against Gouda, they decide to use a hit-and-run strategy against Hakai-O since it specializes in close quarters combat. The plan seems to work for a little while, until Gouda shows them his LBX's true abilities by first activiting the Gao Cannon and swiftly destroying Kazu's Warrior. Without their teammate, Ban and Ami are in a pinch. The first blast from Hakai-O's cannon was a demoralizing tactic, but they don't give up. In fact, Kazu finds out Hakai-O's Achilles Heel.
