Ep. 10: Kaito investigates cheaters while monopoles fall, prompting Subaru to suggest a new GunBuild robot to JAXA.
Aired on December 14, 2012

Kaito identifies a Kill-Ballad cheater as a monopole stone falls nearby. Akiho considers using these stones to power the GunBuild-1, but Subaru advises abandoning it for a new robot with JAXA. The group meets Nae to persuade JAXA, where Subaru presents a report on the first run's failures and proposes an improved design. He incorporates Junna's idea to use augmented reality via Poke-Com to mimic Gunvarrel's appearance, removing the need for extra weight. Akiho accepts that building a new robot aligns with her original dream and agrees to prepare GunBuild-2 for the expo. Meanwhile, Mizuka speaks with Airi, instructing her to disappear from their lives.
