With the Black King's darkness spreading and old allies turning against them, Yuri and Aram's group crosses paths with Shuza, once part of their own alliance, who now wants the Chain Chronicle for himself and blames Yuri's mercy for the war going the way it has. When the corrupted Burckhardt reappears alongside the enigmatic Eirenus, Yuri is offered a place at the Black King's side instead of a fight, a temptation the story leaves genuinely open. This final film closes out the Chain Chronicle: The Light of Haecceitas trilogy.
