Ep. 11: Kona and Kaito unlock Kimijima's Report No. 3 while Gunvarrel's final episode is leaked.

Kona and Kaito complete tedious tasks to unlock the third report, during which Kaito defeats a Kill-Ballad cheater who infects Kona's IRUO software with a virus. Kaito questions Mizuka about Kimijima, while Misaki investigates his reports for her superiors. After using Junna to record GunBuild-2 motions, they access Kimijima's Report No. 3, revealing plans to use a solar storm to alter Earth's environment and eliminate most of humanity, with drone research starting in 2012 by Exoskeleton Inc. Kona discovers the top three Kill-Ballad players were impersonated after being found dead half a year ago, though the leaderboard changes. Gunvarrel's final episode leaks, showing robots falling into a furnace to ignite a solar flare that destroys Anubis and Earth. Kaito notes the similarity to Kimijima's reports, and Misaki warns him to stop investigating Kou Kimijima.
