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.

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.

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.

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.

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.

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

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.

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.

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

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.

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.

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.
