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

Having started the stream, I realized I had no plan at all. Just as I began to panic…

“Kyuui~!”

Something flew towards me from inside the house with a cute sound.

“Oh! Melon!”

It was “Melon,” one of our pets.

“Kyui Kyui~!”

Melon, covered in bright green, fluffy fur, was small enough to hold in both hands, with tiny wings sprouting from the back.

This lizard-like pet has been with me since I was a child. It’s strange that it can fly.

Its name comes from the fruit, melon.

“What’s up, Melon? Curious about what I’m doing?”

“Kyui!”

“Aw, you’re adorable.”

I held Melon close to my chest and stroked its head. I love this feeling.

The comments exploded with excitement at Melon’s appearance.

“Is that your pet?”

Questions naturally followed, and I answered them one by one.

“Yes! My cute pet!”

“Looks more like a monster though.”

“Ah, well…”

I hesitated, then decided to answer.

“It’s because this is a dungeon. Here…”

The chat reacted with surprise.

“A dungeon!?”
“Your home is a dungeon!?”
“Wow!”
“Home dungeon, huh?”

“That’s right.”

Dungeons appear naturally, and their locations are unpredictable.

Our house sits on a “Home Dungeon,” a rare phenomenon where a dungeon materializes within someone’s property.

“I got my explorer’s license to become the master of this house, originally my grandfather’s. He passed away around my high school entrance, and I needed the license to inherit the house with its dungeon.”

The chat understood.

“That’s why you’re F-rank.”
“You’ve only explored this one, your home dungeon.”

Another question came.

“What about your parents?”

“They’re… well, yeah.”

“Sorry…”
“Didn’t mean to…”

“No, no, it’s fine! I have my cute pets!”

“Kyui!”

The chat was touched.

“Melon is taking care of you.”
“Such a brave kid.”

“Kyui!”

“Am I being protected here!?”

Melon seemed to understand the conversation, adapting to the comments.

“Is the dungeon where Melon came from?”

“Yes. Want to see it?”

The chat exploded with excitement.

“Let’s go there!”
“Show us!”
“Really?”
“Can’t wait!”

“Then, let’s head to the basement.”

The dungeon entrance is downstairs. It’s like my house is above ground and the dungeon starts below.

“Here we are.”

I reached the first basement level, the entrance to the dungeon.

“Just a normal door?”
“It’s really inside the house?”
“Wait, doesn’t Melon come from outside?”

“Oh, right!”

I remembered the last comment.

Seems like normal monsters can’t leave the dungeon, but our pets can. I wonder why.

“Why is that…?”

The chat laughed.

“You’re clueless!”
“Love the head tilt.”
“Who’s the confused one now?”

“Let’s go.”

“Kyui!”

I opened the door.

“Welcome to our first basement level.”

A cool grassy area greeted us, with sunlight streaming down, creating a refreshing atmosphere. The lush greenery felt soothing.

“Wow!”
“Amazing!”
“Is this real?”
“A genuine dungeon at home?”

“Yep, it’s really nice here. Look at this.”

I drank from a stream with blue glowing water.

“Ahh, refreshing!”

“Is the water blue?”
“Looks strange.”
“Hinata Hikari: No way…”

“Eh?”

Among the names, “Hinata Hikari” stood out, accelerating the chat.

“Hinata Hikari!?”
“Is that the real one?”
“Wow, a big name!”
“She’s watching this!?”

“Eh, Hikari-san, thanks for watching. Subscribers… 1.5 million!?”

Hikari was a big deal.

“High school S-rank explorer!”
“Super strong!”
“Cutest one!”

“Really? Didn’t know.”
“Hikari: Can you show the water closer?”

“Like this?”

Hikari: “Incredible. That’s ‘Mana Water.'”

“Mana Water? What’s that?”

The chat erupted.

“Mana Water!?”
“Seriously!?”
“Can’t believe it!”
“Hikari wouldn’t lie.”

“What happens if you drink it?”

Hikari: “Many effects, but mainly ‘you become stronger.'”

“Wow.”

I was more accepting than surprised. We’ve always had this water, even using it for drinking and gardening.

Hikari: “Mana Water is a rare item, a miracle if you get a cupful from deep dungeon layers.”

“That’s interesting.”

The chat laughed at my reaction.

“So chill.”
“Love the nonchalance.”
“Unfazed.”
“Should be more shocked!”

“It’s just how I feel.”

“So, that’s why Melon is like this

.”

I looked at Melon…

The chat went wild again.

“What’s that!?”
“How!?”
“Unbelievable!”

I had unintentionally caused a stir with Melon’s appearance.
