As Hajime's deadly duel versus Noint continues, Aiko and Tio hatch a plan to assist Hajime. The other students also notice the alarming noise and gather together to figure out what's going on.

The party to celebrate Liliana's visit to the imperial capital and announce her engagement to the imperial crown prince begins. However, the Haulia Tribe has a whole different event planned for the night.

It's now time to tackle the next Great Labyrinth, located deep within the Haltina Sea of Trees. Immediately upon entering, it is made clear to Hajime that this is not going to be a straightforward hack-and-slash adventure.

Hajime catches wind of conflict brewing between the empire and the rabbit beastmen.

Daisuke and his shadowy co-conspirator overtly take action against Commander Meld, triggering the final phase of their nefarious plan. Meanwhile, Hajime encounters a group of bandits attacking someone he has met before.

With her trap sprung and all of the students rendered unable to fight, Eri reveals her true nature and sets the rest of her plan in motion.

Hajime wakes up from the dream trap and waits for the others to break free as well. As they progress deeper into the labyrinth, many more mind-rending attacks are thrown against them.

With the Heiligh Kingdom heavily damaged, Princess Liliana travels to the Hoelscher Empire to request their aid. On their way, Hajime spots Haulia tribe members fighting imperial soldiers. The tribe members bring news of a coming invasion.

When Hajime's classmates are threatened by a demon mage to "join or die", it's up to him to rescue them -- whether they like his methods or not.

Several days have passed since Hajime and his party returned safely from the Sunken Ruins of Melusine. Though Hajime knows he needs to get going, he doesn't want to break Myu's heart.

Liliana meets the emperor to discuss receiving aid from him. She must make a great personal sacrifice to solidify this. She is ready to do so, but Hajime seems to have other plans.

After the Haulia Tribe's victory over the Empire, Hajime and the others travel to Verbergen to prepare to take on a new Great Labyrinth. During his visit, Hajime gets an opportunity to deepen his bond with Shea.

Yue notices something during her test and wants to warn Shea about it, but Yue's phrasing triggers Shea's outrage.

Hajime arrives at the Divine Mountain to rescue Aiko, but is immediately attacked by Noint. Meanwhile, a massive force of Demons and monsters suddenly appear just outside the capital city of Heiligh and immediately begin sieging the city.

Hajime once again saved the day, thwarting Eri's evil plans and the demons' invasion. With the royal capital now safe, Hajime discusses future plans with his companions and classmates.

Another trap activates, reversing the emotions each party member holds against the others. Hajime and Yue hate each other, while Kouki has nothing but respect towards Hajime. Moreover, they all fall in love with the enemy.

With all but one Great Labyrinth conquered, Hajime and the group travel to the Schnee Snow Fields to tackle the final labyrinth. Meanwhile, it becomes clear that certain members of the group have internal issues to deal with.

Aside from pointing out what a huge edgelord Hajime is, the labyrinth begins pointing out other painful realities that Hajime was trying to look away from. Meanwhile, Shizuku is subjected to the same ordeals.

Hajime and Yue attempt to harness their new power to realize their ultimate goal - creating a way home.

Hajime's party makes their way back to a familiar location. Deep in the Labyrinth, a new foe threatens the lives of his classmates.

Hajime's party reaches Ankaji. Hajime must perform multiple miracles to save this dukedom from certain doom before traveling to his real destination, the Grand Gruen Volcano, the next labyrinth on his list.

Tio escapes the volcano alone and flies towards Ankaji. Meanwhile, Hajime and the others, still in the volcano, hatch a plan to escape the incoming lava without sacrificing any of their goals.

Hajime's classmates struggle with the aftermath of Hajime's fall. Hajime descends even further into the Labyrinth, where he makes a fateful encounter.

Hajime and Yue descend deeper into the labyrinth, discovering one another's stories along the way.

A rare oasis lies in the depths of the Labyrinth. There, Hajime and Yue come face-to-face with the specter of the labyrinth's namesake.
