"I wanna be stronger. Strong enough to protect everyone. I need to be...!!" Eager for a new challenge, Haruhiro's party descends into the Cyrene Mines--the lair of the kobolds and the resting place of Mary's former allies. But not long after the combat starts, tensions between Ranta and Haruhiro begin to flare, and when the group finds itself up against an unspeakably powerful foe, Haruhiro is forced to make an impossible choice... The party faces its greatest challenge yet--the ominous monster Death Spots!

"Choco. Wait, could it be that Choco...?" Haruhiro and his comrades have become famous due to achievements no one expected from them. With his comrades more confident, Haruhiro is still agonizing over what to do when more experienced volunteer soldiers come to him. Among them is a girl whose name is still in Haruhiro's memories. At that same time, the town of Alterna moves to retake the Deadhead Watchtower held by orcs. Looking to earn some of the reward money, Haruhiro's party ends up joining their first raid alongside Renji and Choco.

By the time Haruhiro comes to, he finds himself in a gamelike world filled with terrifying monsters. This world is called Grimgar. Armed with no more strength or ability than your average boy, Haruhiro and his fellow party members struggle to survive as they cobble out a mean existence, receiving mediocre pay in return for risking their lives everyday. What kind of future does this harsh, uncaring world have in store for those who are not destined to succeed, who have no prophecy to guide them, who are not heroes...?

"You don't wanna die, huh? Me neither...!" By hunting goblins to earn money, Haruhiro and his party are doing all they can to survive in an unfamiliar world. But during one of their hunts, Manato, their leader and healer, falls to a goblin's dagger, and with no one to heal him, the group is forced to bury their friend. Now, with no priest and little hope for the future, they must find a way to endure the many trials ahead. Can they really cope with the loss of their most important ally? The desperate struggle continues as a beautiful cold-hearted priest named Mary joins the party!

"Don't scare me like that, Moguzo." "Sorry, sorry." Moguzo let out an embarrassed laugh and scratched the back of his head. Still, he sure is bleeding a lot, Haruhiro thought. With all that blood, it's impossible to tell what kind of face he's making. But, well, it looks like he's fine somehow. Haruhiro and his party reached the end of one major battle. However, with there being some comrades they couldn't save, they couldn't be entirely happy with how things were. Meanwhile, because they managed to accomplish more than anyone had expected, some members of the party receive offers from other teams wanting to poach them, too. As Haruhiro agonizes over what to do as a leader, he is forced to come to grips with what the party wants to do once again. The story of adventure born from the ashes now enters a new stage!

Under the command of Jin Mogis, the Kingdom of Arabakia's Expeditionary Force declared independence as the new Frontier Army. They then formed an alliance with the king of the goblins. Now, their next move is to conquer Mount Grief, occupied by an army of orcs. Entrusted with an important mission to infiltrate and disrupt the enemy from within, Haruhiro and his team work with the members of Shinohara's Orion, Team Renji, and the Tokkis in order to break through the "Graveyard" beneath Mount Grief. However, the mission proves more difficult than they imagined, and they are faced with nothing but close calls and dangerous foes. Forget about taking Mount Grief, are they even going to be able to survive this?! Fighting alongside old comrades. Feeling conflicting emotions during a battle to the death. Is the team headed toward hope or despair?

With great sacrifice, the Arabakia Kingdom Expeditionary Force succeeded in retaking Alterna, but Haruhiro finds himself crushed under the weight of what he's lost. The ambitious General Jin Mogis of the Expeditionary Force, the survivors of the Volunteer Soldier Corps, and the mysterious residents of the Forbidden Tower. In the middle of these different factions, each with their own goals, Haruhiro's party has one of their own members taken hostage, and are forced to go on a dangerous mission. Incredibly, their goal is... an alliance with the goblins?! As the team struggles, unable to find a way out, the man who once shared their joys and sorrows, but was forced to go down a different path, reappears! Now that Haruhiro and his party have lost their memory once more, the bonds they formed in Grimgar will become their strength.
