The only one who was kind to me was my ex-girlfriend’s super cute younger sister.... more>>

My name is Koichi Okita, and I was a frontline fighter in Japan’s strongest party, tasked with conquering the Tokyo Dungeon—one of the seven high-level dungeons that must be cleared to prevent the world’s destruction.

The road to dungeon conquest was harsh, grueling, and long. After six months of relentless exploration, I returned, carrying my wounded comrades, only to be met with betrayal—my girlfriend had been stolen by the party leader, who had stayed behind due to an injury. On top of that, I was unjustly blamed for the expedition’s failure.

Once the strongest explorer and a highly popular dungeon-streamer, my reputation crumbled overnight. Amid public backlash and relentless criticism, I left the party.

I didn’t care anymore. They could do whatever they wanted.

That’s what I thought—until only one person stood by me: Haruka Miyanaga, my ex-girlfriend’s younger sister and a fellow party member, who comforted me in my lowest moments.

After leaving the party, I realized something—aside from Haruka, the rest of them were tr*sh. And so, with a newfound sense of relief, I moved forward… <<less

I Was the Leader of This City's Top Adventurer Party—Betrayed, Cast Out, and Left for Dead, But Now I'll Show Them My True Power... more>>

I was the leader of this city's top adventurer party. Dungeon exploration is a life-or-death battle, and today was no different—we were fully prepared for the challenge.

But then, our party’s thief screwed up. Disarming traps is his job, isn’t it? So why the hell did he step right onto one? As the leader, I did what I had to—I shielded him. The result? I fell into the dungeon’s deepest layers.

What followed was pure hell. Swarms of monstrously powerful enemies, starvation, poison—I fought tooth and nail, never knowing which way to go. Somehow, against all odds, I survived. And after months of struggle, I finally made it back.

What was waiting for me?

Betrayal.

My fiancée and that damn thief had stabbed me in the back. Are you kidding me? Since when was it my fault that I triggered the trap and put everyone in danger?!

Get out of the city? Like hell I’d stay after this!

At least, that’s what I thought—until my ex-fiancée’s little sister was the only one to comfort me.

I was ready to walk away for good. The city, the party—I didn’t care anymore.

But then, she was in danger.

And of course, I’m going to save her.

Time to show them the power of someone who survived the dungeon’s deepest layers! <<less

“Divorce? Pardon me? If you go through with that, you’ll be the one facing ruin—are you certain you’re prepared for that?”... more>>

I am a Countess.

My husband, the second son of a Duke’s family, has been engaged to me since childhood. However, he is nothing but a shameless philanderer. Then one day, of all things, he had the audacity to declare that he wanted a divorce.

So, I made it clear to him:

“The title belongs to me. This house, the retainers, and the fortune are all under the Countess’s name. If we divorce, what exactly do you plan to do?”

Panicked, my husband started spouting the most absurd nonsense. I, however, found it so utterly ridiculous that I dismissed him without hesitation—and then locked him in his room.

Even after that, he continued to flaunt his carefree nature, and every time, I made sure to put an end to his antics. But then, one day… he disappeared.

"Do I miss him? Absolutely not. That fool—" <<less

Explorer Training Academy. It is a school created by the country to train those who explore dungeons that suddenly appeared in the world. The resources obtained from dungeons are so valuable and powerful that they significantly influence national strength, leading both the country and society to fully support explorers. Top explorers are considered heroes, and those who stream their explorations are popular figures.... more>>

Tōma Yumeno, who transferred to this academy, used to belong to a reverse harem party led by an S-rank explorer but escaped from the leader’s s*xual harassment, hoping to spend his remaining time until graduation without standing out.

Meanwhile, in his class was the beautiful Sakura Amagi. “Huh? Is she an angel?” However, despite being an incredibly strong solo explorer, she was isolated due to her negative unique skill, “Magical Power Release,” which harmed those around her.

Soon after transferring, Tōma found himself fighting next to Sakura thanks to his unique skill, “Grit.”

This is a story about Tōma, who aims for a “laid-back yet moderately relaxed” life. Unbeknownst to him, his talent attracts attention, and he reluctantly grows to aim for becoming an S-rank explorer. <<less
