After he and his entire class are summoned to another world, Hajime Nagumo finds himself extremely underpowered and at the mercy of the Labyrinth.

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.

Hajime and Yue encounter a powerful foe in the deepest depths of the Labyrinth. Will they be able to defeat it and find a way out?

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.

After finally making it back to the surface, Hajime and Yue encounter a rabbit girl who claims she's been "waiting for them" -- and needs their help.

Hajime, Yue, and Shea forge onwards, their next labyrinth in sight. However, the Liberator of this Labyrinth is quite the unusual character.

Hajime and the gang reluctantly accept a quest. Their journey north to the town of Ur leads to an unexpected reunion with their teacher, Aiko.

Hajime's quest leads him and his classmates into the mountains, where they come across their quarry -- and the huge black dragon attacking him!

With an army of monsters approaching the town of Ur, Hajime sets a plan into motion to protect the citizens and exalt Aiko as the Goddess of Plenty.

After returning to Fuhren, Hajime heads off on a date with Shea, which comes to a sudden close when they stumble on a kidnapped merfolk girl.

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

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.

Shizuku and the other students return to the royal capital. Their brush with death, and the dramatic reencounter with Hajime Nagumo, has had different effects on each student's mind. Hajime, now joined by Kaori, arrives at the Gruen Desert.

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.

Hajime completes the grueling trial at the end of the Grand Gruen Volcano labyrinth, but at that exact moment, Freid, a demon commander, launches a surprise attack. Hajime is heavily injured, and a desperate battle begins.

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 and his party departs the city of Erisen to head towards the Sunken Ruins of Melusine. They solve multiple puzzles to reach the labyrinth, and are confronted by a mysterious illusion.

Hajime and Kaori, separated from the others, move deeper into the labyrinth. They encounter an even more disturbing illusion, but Kaori has more important concerns - does she really want to continue this relationship with Hajime?

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.

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.

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.

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.

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 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.

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.

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

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.

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.

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.

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 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.

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.

Hajime finally confirms that learning all of the ancient magics can help him return to Earth. With this newfound hope in heart, he reaffirms the bond between him and his friends - including someone whom he now treats as more than a friend.

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.

As the party pushes deeper into the labyrnth and reach an area where all of the icy walls are reflective, like a mirror. The mind games begin, and Kouki is the first to fall prey to the labyrinth's tricks.

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 rescues Shizuku in the nick of time, just as she was about to succumb to the labyrinth's trial. Suzu, Ryutarou and Tio also face their own tests.

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

Kouki's test pushes him to face his insecurities about Hajime head-on.

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