An unusual application had mysteriously installed itself on my smartphone, and within it, an alien organism was growing.

Johann Grecia belonged to the hero party as an adventurer with the SSS-rank skill [Architect]. He contributed to the suppression of the demon king in his own unique ways. Such as building a guild in the vicinity of the Demon King’s castle, or building a trap house to destroy many demons.... more>>

However, on the very day the heroes brought down the Demon King, he was branded as useless, and pressured by the party to leave. Furthermore, all his qualifications as an adventurer have been revoked, and all the constructions he produced with his skill had been taken.

Johann who lost everything, does not care about building with his skill anymore, and is currently camping all alone. Around that time, he encountered a little girl who seemed to have the same idea.

“The Castle of Felukia… It’s completely lost…”

But it seemed that this girl, was the Demon King’s daughter! The castle of Felukia used to belong to the demon king, but the heroes invaded it. It seemed likely that this girl had lost all her relatives. And thus Johann made up his determination.

“Leave it up to me! I, for the sake of Felukia, will build a new Demon King castle!”

“Eh?!” she said as she almost danced in joy. And so Johann promised to build the most beautiful, highest difficulty, most brutal castle for her. “And if the heroes invade the resurrected Demon King castle again, I will repel them with my [Architect] skill!” <<less

*Sigh* “Another day with 0 viewers and only 3 subscribers… Am I just not cut out for this, I wonder…”... more>>

Karlin Yamada, a high school girl who streamed dungeon exploration, was on the brink of losing hope.

Inspired by elegant explorer characters from anime, she had started her channel a year ago as a noble lady conquering dungeons in a dress. Yet, whether due to her concept or her videos lacking entertainment value, despite her potential as an explorer, her channel remained stagnant.

One day, while exploring the lower levels of a dungeon, Karlin spotted a peculiar man.

“Well, I’m gonna set off an explosion now~”

In his hand was a dangerous substance prohibited by the country, on the verge of ignition—

“What the heck are you doing? Geeez!”

Her ladylike demeanor forgotten, she delivered a swift punch. Along with her scolding, she promptly rendered the man unconscious.

“It’s fortunate I ended the stream before this. I can’t possibly broadcast such an indecent scene,” Karlin mused, carrying the man outside and taking him home.

However, behind the scenes…

“Who’s that high-and-mighty rich girl!?”

“Why did the rising star explorer get knocked around unilaterally!?”

“Seriously, why’s she wearing a dress in the lower levels!?”

“Isn’t she completely nuts!?”

The man Karlin had dealt with was a notorious troublemaking dungeon streamer. Her action of physically stopping his dangerous behavior was globally broadcasted. The video of the young, promising explorer being lectured by a mysterious young lady started going viral. Karlin’s account was swiftly identified due to her accidental failure to end the stream. By the next morning, she unwittingly became a legend.

In this manner, Karlin’s extraordinary strength and exceptional feats gained exposure and continued to trend. Her popularity and influence transcended the boundaries of streaming, evolving into something much bigger. <<less

She thought it was certainly impossible.

“No, I’m just the master of this dungeon…”

“Yes, that’s right. If so, you’re my master.”

Somehow, she gained a perfect manager as soon as she arrived in the dungeon.

“Don’t touch that unsightly bastard. Eat me instead.”

Presenting oneself as nourishment was one of the greatest predatory demons in Devildom.

“I brought the prince’s neck as an offering to you.”

And offering her a legendary adventurer she didn’t even ask for.

Okay. If it has already come to this, then the goal is to become S-class! <<less
