Three more episodes of Hirano at full volume, and they hit like the TV run never stopped. This is where the Black King stops being a silhouette on a throne and starts being a person, and the reveal recontextualizes every atrocity the Ends have committed up to that point. Meanwhile Toyohisa is still Toyohisa, grinning like a lunatic with a sword in each hand, Nobunaga is still treating a fantasy war as a gunpowder logistics problem, and Yoichi still ends arguments from three hundred meters out. The animation and that ink-heavy, snarling Hirano face design carry over intact, so it slots in as episodes 13 through 15 rather than a cheap bonus. Fair warning: it does not end, it stops. You will finish these and immediately go looking for a manga chapter that Hirano has not published yet, and that ache is part of the deal.
Three OVA episodes extend the Drifters story, an action fantasy with a streak of comedy and adventure. The Ends have been driven back from Verlina, yet the fighting is far from finished. Monster armies regroup while the Black King strengthens his hold on the lands he has already taken. Across Orte, fresh clashes break out as its surviving forces try to keep demi-human races, oppressed for years, under their rule. The Ends grow stronger by the day, and Toyohisa Shimazu lies unconscious from the severe wounds he took at Verlina. With threats closing in from all directions, humanity's survival hangs in the balance. Episodes 13 and 14 never aired and came with the home video release, while episode 15 was packaged with the sixth manga volume.
