Aired on October 5, 2021

Set in 2061, Japan remains divided into four occupied regions following the Boundary War, a mid-20th century conflict where foreign powers used autonomous mecha units called AMAIMs to control the failed state. Amou Shiiba, a young orphan, is repairing an abandoned AMAIM when he discovers an AI core named Gai. After saving Gai from battery depletion, Amou integrates the AI into his salvaged machine, which Gai identifies as a rare manned model called Kenbu. When Oceanian mercenaries falsely accuse Amou and his scavenger companions of terrorism, he is forced to pilot Kenbu to destroy the attacking AMAIMs sent to capture them.
