Synopsis

Luka is unexpectedly brought to the dangerous lower sector by Instructor Kinuan, who then introduces him to the Arkies combat method, a unique fighting style that emphasizes adapting to one's abilities, but comes with significant side effects, including brain problems. Meanwhile, Luka learns about a brewing rebellion against the empire, adding internal strife to their war with the Corite Alliance. Despite his concerns, Luka expresses his desire to get stronger even with the risks and makes plans to meet with someone in the lower sector again.
