The sci-fi mecha action of the 86 EIGHTY-SIX anime—based on the light novel series written by Asato Asato and illustrated by Shirabii—is back in action in its second cour, so naturally there’s a new OP to go along with it. The theme song this time around is “Kyokai-sen” (“Borderline”) by amazarashi, and you can check it out on its own thanks to Aniplex’s recent YouTube upload below.
A-1 Pictures (Sword Art Online) produces the 86 EIGHTY-SIX anime, with Toshimasa Ishii directing.
Crunchyroll streams the series and describes it below:
Called “Juggernaut,” these are the unmanned combat drones developed by the Republic of San Magnolia in answer to the attacks by the autonomous unmanned drones of the neighboring Empire of Giad, the “Legion”. But they’re only unmanned in name. In reality, they are piloted by the Eighty-sixers—those considered to be less than human and treated as mere tools. Determined to achieve his own mysterious ends, Shin, the captain of Spearhead Squadron, which is comprised of Eighty-sixers, continues to fight a hopeless war on a battlefield where only death awaits him.
