EX-ARM
Summary
Akira Natsume seems to almost have a phobia of electrical devices while also being very good at diagnosing them. He resolves to change himself for the better and get a girlfriend like his older brother did... But then Akira suddenly dies in an accident. 16 years later a special policewoman and her android partner retrieve and activate a highly advanced AI and super-weapon called EX-ARM and put it into full control of their ship as a last resort. Turns out the AI is actually just Akira's brain!
... and the second season of the Anime did a better job of pacing than I thought they would. I think they moved the Elf village arc from before hostilities with the Principality began to the inter-war period, aka the start of the second season, and used that to pad it out. Good call if that's what they did. In any event. Good season.
