Back to the Battlefield: The Veteran Heroes Return to the Fray!

The century-long war with demons was finally brought to a close by seven young heroes who slew the demon lord, routed the demon army, and ultimately led humanity to victory. The heroes then went their separate ways, and the land has been at peace for twenty-five long years...until now. Alan Granger, a former hero, enjoys a quiet life as a commander in the Royal Knights until the day he receives a report that shakes him to his core: the demon army has returned! He immediately knows what he must do—gather his old compatriots and face the demon army once again. But Alan and his friends are now all in their forties, while the demons are more powerful than ever. Do these veteran heroes have what it takes to leap back onto the battlefield and save the world a second time?

After taking down the former members of the Seven Black Stars and stopping their invasion, Alan now takes a trip to meet with an old comrade, Kevin the Unrivaled Gadabout. Alan’s goal is to convince the whimsical yet world-weary Gadabout to fight with them once again, but there’s one small problem: Kevin feels like that’s far too much of a hassle. With trouble brewing on the horizon as the New Seven Black Stars begin to make their next moves, will Alan be able to persuade Kevin to take up arms and join the rest of the Seven Heroes on the battlefield? And what exactly does Demon Lord Beelzebub have up his sleeve?

Dora’s victory has brought some hope for humanity, but the war is far from over. The next step of the demons’ invasion takes place in the Fifth Kingdom, home to Kevin the Unrivaled Gadabout. He’s up against Atlantis the Ultimate Slime—a young shenmo boasting a vast arsenal of skills—and his army of aquatic demons. But those two aren’t the only ones entering a decisive battle. Twenty-five years overdue, Beelzebub has come to the First Kingdom to challenge Alan. The two of them, along with the stubborn Rosetta, leave the city to find a suitable location for the ultimate grudge match. In the battle of experience versus demonic power, which will come out on top?

The demons continue their invasion in full force as the remaining members of the New Seven Black Stars join the fight against humanity. The Great Six take on Loki to protect the Seventh Kingdom. Unfortunately, they’re outmatched in every single ability. Will they manage to prevail with some help from the hapless Yoshida? Elsewhere, Alan and Beelzebub finally exchange the first blows of their fated confrontation. The demon lord is much stronger at first glance, but the Champion of Light is not one to stand down while his opponent still draws breath. Meanwhile, Isabella the Villainess plays against Adek the God of Games, a shenmo with the ability to take people’s lives when he wins a game. The two of them must try to outsmart the other in a battle of wits with the lives of the entire Fourth Kingdom riding on the line. And what demon will the blackhearted Derek take on with his merciless brainwashing magic? It’s all coming to an end in this climactic volume!
