The F-rank Adventurer, Who Was Supposed to Be Just a Helper, Accidentally Goes Viral for Blowing Away an S-rank Monster – It Seems the Home I’ve Been Living in Was an Unusually Powerful Dungeon Inhabited by the Strongest Species

The chapter you provided is in Japanese, and it appears to continue the story involving characters such as Hikone Hoshi, Saruyama, and Erika. Here is the English translation:

—

“You there.”

In the twilight, a man addresses a floating camera.

The man entangling with Hoshi was Saruyama.

“Here he comes lol”
“What’s he gonna do today?”

Saruyama had started his stream.
As Hoshi’s classmates said, Saruyama was a streamer.
He begins talking about the content of his broadcast.

“Recently, there’s been quite a topic of discussion, hasn’t there?”

“Topic?”
“What’s he talking about?”
“Could it be…”

“Was it… mana water, I think?”

“It’s Hikone Hoshi’s stream!”
“I knew it!”
“What’s he planning?”

“Today, I’m thinking of going to get that lol”

“Nice lol”
“Go for it”

Saruyama’s concurrent viewers exceeded 1,000.
It pales in comparison to Hoshi, but it’s a high number for an average person.

The reason is that Saruyama was a nuisance streamer.
Doing bad things stands out in streaming too.

But naturally, this draws the attention of those charmed by Hoshi.

“What?”
“Stop it”
“I like Hikone Hoshi, don’t do it”

“Shut up!”

He immediately blocks comments defending Hoshi.
Making sure they can never comment on his streams again.

“Silent, you Hikone followers!”

“It’s getting heated lol”
“Go for it lol”
“I didn’t like him anyway”

“I’m reporting this”
“I’ll clip this”
“This needs to be exposed”

Opinions were divided.
The fate of a nuisance streamer.

“Isn’t this basically theft?”

“Ha. Don’t you know? A dungeon is a dungeon, even if it’s a home. Anything I get there is mine.”

Technically, that’s incorrect.
The rule is, “If you have permission to enter someone’s home dungeon, you can take what you find.” Saruyama was confident he could fulfill this.

“Let’s get going then.”

Finishing his intro, Saruyama starts walking.
He was already near Hoshi’s house.
He had followed the route Hoshi took on his bike.

“Oh?”

As he starts walking, he spots a woman by a large house and immediately turns off his hologram comments, switching to a hidden-camera style stream.

The moment he does, the woman turns towards Saruyama.

“Oh my.”
“…!”

Saruyama’s eyes widen.

(It’s her! The elf sister!)

Despite his jealousy, Saruyama had been watching Hoshi’s streams carefully.
He quickly recognizes her as Erika, Hoshi’s sister figure.

Caught off guard, Saruyama tries to find an angle, but Erika smiles.

“Are you a friend of Hoshi-kun?”
“…!”

At her words, Saruyama grins.

“Yeah, that’s right.”
“Oh, I thought so!”

Erika clasps her hands in front of her chest.

“But I’m sorry. Hoshi-kun just left.”
“Is that so?”
“Did you have an appointment with Hoshi-kun?”
“…!”

(Big chance)

Saruyama was wondering how to lie, but she offered him an opening.

“Yeah, he was going to show me his underground dungeon.”
“Really!”
“But it’s impossible without Hikone… Hikone-kun, right?”

Saruyama provocatively asks Erika.

“No, no! If it was a promise with Hoshi-kun, it’s okay!”
“…!”

(What a fool!)

“Really?”
“Of course. You’re a friend of Hoshi-kun!”
“Hmph. Thanks.”

Saruyama struggles to contain his laughter.

The rule was fulfilled.
Now he could take something from Hoshi’s home dungeon.

(Easy win!)

Saruyama follows Erika into Hoshi’s house.

★

“This way.”
“Thanks.”

Erika leads him into the house and towards the underground dungeon.
Saruyama can hardly contain his laughter.

(Can’t believe it’s going this well)

He was surprised by Hoshi’s stream, but Saruyama had his own plans.
It was Erika, who appeared accidentally in the broadcast.

(Haha!)

He met her by chance, but Saruyama intended to deceive her.
He thought she was easy to fool.

(She’s so naive, it’s a relief)

Finally, Erika stops in front of a door.

“Here we are.”
“…Oh, right.”

It’s the first-floor door he saw in the stream.
As the door opens, Saruyama exclaims excitedly.

“Whoa!”

Before him lies the grassland area.
Exactly as seen in Hoshi’s stream.

But ignoring the scenery, Saruyama has only one

goal.

(There it is!)

The river of mana water.
Having thoroughly reviewed the stream, he quickly finds it.

Then, one last check.

“By the way,”
“What’s up?”
“Where are the pets right now?”
“Hmm…”

Erika responds, touching her lip.

“Probably on the third basement level.”
“Uha!”

(I won…!)

Convinced, Saruyama’s legs are already moving.

“Oooh!”

He heads straight for the mana water river.
With his dungeon-explorer-trained speed, he runs towards the river, faster than an average person.

“Whoa!”

First, he goes to take a drink with gusto—but can’t.

“…Gahh!!”

Suddenly, a massive figure appears from out of his field of vision.
Blown away by it, Saruyama crashes into the wall with force.

“Ow! What the… what!?”

“—Gyaaooo!”

What he sees when he looks up is the formidable S-rank monster he’s seen plenty of times in the streams.
A dragon, the one called Melon.

“Where did it come from!?”
“It was here from the start.”
“…!?”

Saruyama, still sitting on his bottom, slowly turns towards the voice.
But this voice, unlike before, is low and cold.

“That talk about pets was a lie. You’ve finally shown your true colors.”
“My true colors? …!”

Saruyama realizes.

“You, you’ve got to be kidding!”
“Huhuhu.”

He had been the one deceived all along.
This had been the plan from the start.

“Welcome.”
“…!?”

As Erika speaks, monsters start to emerge from the bushes.

“Grrrrr…”
“Boooo…”
“Ufufufu…”

A silver wolf, a bird wrapped in flames, a woman with the lower body of a fish…
Fantasy creatures like he’s never seen before gaze at Saruyama as if he’s prey.

“Wh… what…?”

Saruyama’s focus blurs at the sight.
Erika adds insult to injury.

“You might want this too.”
“What are you…?”

Erika operates the floating camera.

“Captured perfectly ♡”
“!!”

“The moment’s here!”
“Hello~ lol”
“Busted!”
“Serves you right!”
“Watching?”
“Don’t mess with big sis.”

She turns on the hologram comments.

(She knew about the camera from the start…!)

Erika had known about the camera floating behind Saruyama all along.
She had deliberately invited him to record the footage.

“So, what will you do now?”

Saruyama looks at the monsters with a terrified expression.

“Gulp…”

His instincts as an explorer tell him.
The monsters before him are unbeatable, no matter what.
They’re not even a match.

“Huff, huff…!”

Then, Saruyama’s eyes widen.
He thinks of his last resort.

“Uaaahhh!”

He runs towards Erika.
He thinks to capture the seemingly weak Erika and use her as a bargaining chip.

—But that’s not to be.

“Oh my.”
“…!?”

Vines sprout from the grass at his feet, lifting Saruyama up.

“Whoa!?”
“He controls vines!?”
“Awesome!”
“Typical elf!”
“Using nature!”

“Thought big sis was weak?”
“…!”

Erika speaks coldly, her eyes still cold.

“I’m the strongest, you know.”
“… Ha, ha.”

It’s over.

Saruyama finally understands.
It wasn’t that Erika seemed weak.
She was too strong for him to even measure.

With that realization, Saruyama gives up.

But at that moment, Erika suddenly looks towards the entrance and speaks again.

“Oops, sorry. I’m not the strongest.”
“Eh? Then who is—”
“Be-hind you.”
“…!”

Saruyama turns in the same direction as Erika.

“Wow! What are you doing, big sis!?”
“…!”

There, running down the stairs, is Hoshi.

“… Ha, ha.”

Saruyama lets out a dry laugh.
Realizing how foolish he’s been.

The strongest of the S-rank monsters are all here.
And his classmate, Hoshi, stands above them all.

“It’s Saruyama-kun!”
“… Hikone. I—”
“Big sis, let him down right away!”
“!”
“Really, Hoshi-kun is always too soft.”

Erika chuckles and releases the vines.

“Are you okay? Saruyama-kun.”
“Ah, ah…”

His classmate who he’s been antagonizing at school.
But now, he feels nothing of the sort.

“I don’t know what happened, but sorry.”
“I, I just…”
“But you know, Saruyama-kun.”

Hoshi says with a bright smile.

“Come visit again!”
“…!”

Saruyama screams internally.

“As if I’d ever come back!!”

“Brutal lol”
“Brutally funny”
“Unaware lol”
“That’s Hoshi-kun for you lol”
“Broke his spirit lol”
“Like he’d ever come back lol”

Thus, Saruyama, the nuisance streamer and Hoshi’s classmate, fails in his strategy.
Though the stream only had about 10,000 viewers, this somewhat terrifying footage spread as a “clip”, becoming a deterrent to approaching Hoshi’s home dungeon.

Approach that house with ill intent, and you won’t leave

with your life.
