Dogora activated his extra skill and destroyed Rezel's second heart with a full-force attack. However, it still wasn't enough to inflict a fatal blow on Rezel, and Dogora was defeated by a counterattack. With no options left and victory seemingly impossible, and even retreating proving difficult, the "Degenerate Gamer" was cornered. At that moment, who descended upon the battlefield?!

Thanks to Allen's efforts, the hero Hermios arrives in Rosenheim. Just when it seemed the "hardcore gamer" had gained a reliable ally, Hermios appears opposed to anyone other than himself and Allen fighting Rezel. So Dogora and Krena decide to spar with him to prove their strength... The next day, Allen and his group begin their operation to recapture the capital, Fortenia.

The other members of the "Abandoned Gamers," excluding Allen, prepare to defend the recaptured Lapolka Fortress. Meanwhile, Allen, through his summoned beast, consults with Hermios in the Gearmut Empire about something concerning the future... Afterwards, Allen takes on the task of annihilating the Demon Lord's army invading Nest and begins the battle. However, he finds himself unexpectedly struggling against the enemy, who attacks relentlessly without giving him a moment's rest.

Having successfully defended Tiamo, the group then began their operation to recapture the fallen Lapolka Fortress. Allen and his advance troops infiltrated the fortress and immediately began fighting. With the support of the rear troops, Allen and his men, despite being overwhelmingly outnumbered, gained the upper hand in the battle, and victory was finally within their grasp. But at that moment, the three demons who had been leading the invasion of Rosenheim appeared on the battlefield.

The group resolved to face the Demon Lord's army of a million in Tiamo. First, they employed delaying tactics to buy time to prepare to intercept the "hardcore gamer." Thanks to these tactics, they succeeded in delaying the enemy's arrival in Tiamo and weakening their forces. However, the enemy's advance did not stop, and the "hardcore gamer," who had been fighting continuously, became exhausted. Furthermore, Allen's magic stones were running low!?

Allen and his companions defeated over 40,000 monsters in one night. Without even taking a break, Allen completed the distribution of healing items and the deployment of summoned beasts in the three towns other than Tiamo. In return for these efforts, Allen met Rosen, the Spirit King who had prophesied his own fate. Allen asked Rosen to put all the "hardcore gamers" into "Hell Mode"...

The Demon Lord's army has launched an invasion to disrupt the intercontinental alliance. Realizing this, Allen and his companions head to Rosenheim, a key location to thwart the enemy's plans. Visiting Nest, a town serving as a refuge, they begin providing aid to the wounded and refugees, as well as gathering information. It is then discovered that Sophie's mother, the Queen of Rosenheim, is in Tiamo, on the front lines of the battle against the Demon Lord's army!?

The final match of the academy martial arts tournament began between Allen and Hermios. In the early stages of the match, Allen was forced onto the defensive against Hermios's swordsmanship, which boasted overwhelming speed and power. However, he began to counterattack after summoning a newly acquired B-rank summoned beast, and gradually pushed back. Hermios then unleashed a blow without holding back. Meanwhile, Allen had a special secret weapon prepared for his opponent, the hero.

Allen and his friends have advanced to their second year. Along with the promotion, Sophia Lone (Sophie), the princess of the elf kingdom of Rosenheim, her bodyguard Formar, and the dwarf Meruru transfer into their class. The three, now members of the "Retired Gamers" club, join Allen and his friends in challenging a B-rank dungeon in an attempt to level up. Time flies, and it's almost summer vacation. Allen and Crena are summoned by the headmaster once again...

Allen and his friends find Dogora and Cecil, who were teleported away by a dungeon trap. After reuniting and overcoming the critical situation, the group reaches the lowest level of the dungeon. There, they begin battling the boss monster, aiming to become the first A-rank dungeon conquerors. After the summer break, Allen and Krena are summoned by the headmaster. The two are offered the opportunity to participate in the school's martial arts tournament, which is scheduled to take place in one week.

With Kiel officially joining the party, "The Gamers," they embark on a quest to conquer a B-rank dungeon. They steadily defeat the monsters that appear as they make their way to the lowest level of the dungeon. Two months later, finally... Then comes summer vacation. Allen reports to Lord Granvelle about the promise Kiel made with the royal messenger. During their conversation, the two realize a certain plot lurking behind the promise.

The new students are told by their homeroom teacher that their summer homework is to conquer a dungeon. In preparation for the assignment, Allen recruits new party members. As a result, Kiel, who has the talent of a "priest," joins the group. However, Kiel seems to have some kind of secret!? Later, Doberg, who has the talent of a "sword saint," comes to the academy as a special lecturer. During the lesson, when Krena asks Doberg how to use his skills...

Allen, along with Cecil, the reunited Krena, and Dogora, arrives at the Academy City of the Latache Kingdom to take the entrance exam. Before the exam, the four undergo an "Appraisal Ceremony." Allen was previously appraised as having no talent. What will the result be this time...? After the appraisal, the "Hero" Hermios appears before Allen and the others. He seems very interested in Allen's abilities!?
