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

At the spot where the Treasure Mimic had been, an item had dropped. Picking it up, Hoshi curiously tilted his head.

“…A pocket watch?”

The item was palm-sized and round. The outer part seemed to be made of something yellowish-brown. Inside, there were hands and scales from 0 going clockwise, with 100 divisions (he counted with effort).

It looked like a pocket watch but didn’t seem to be telling time.

“Treasure Mimic’s drop item!”
“Super rare.”
“Lucky.”

“It’s rare? Then I’ll keep it.”

Based on the comments, Hoshi decided to keep it. However, he was still curious. He started fiddling with it.

“How do you use this?”

He flipped it over and tapped it lightly. While doing so, he found a protruding part at the top, seemingly a button.

“Click.”

…However, there was no response. Hoshi narrowed his eyes.

“This isn’t broken, right? I won’t forgive if it’s broken.”

His words were innocent, but to the recipient, they couldn’t be more frightening. Somewhere, the Treasure Mimic felt a chill.

“Hie!”
“Hoshi’s unforgiving means certain death.”
“Terrifying kid…”

As he was about to put it away disappointingly,

“Whoa!”

Suddenly, the needle whirred. The hand, initially pointing upwards at 0, spun clockwise to about 80.

“Ah.”

Accidentally, the watch pointed towards Melon and responded. Realizing this, Hoshi grinned.

“Maybe it reacts when pointed at someone.”

He then pointed the watch slightly downwards.

“Cotton Candy, look here.”
“Woof!”

Pointing at Cotton Candy and pressing the button again, the needle moved to about 80, just like with Melon.

“Wow!”

For Hoshi, this was the first time picking up a non-material item in the dungeon. He found it interesting but still didn’t understand the crucial part.

“What does this number mean?”

“Why not point it at yourself?”
“Try it on yourself.”

Following the advice from the comments, Hoshi pointed the watch at himself and pressed the button. The response was not as expected.

“This is…!”

—Trring, trring.

“Huh?”

Then, a familiar sound echoed. It was the notification sound from a smartphone when a call comes in.

“What?”
“A call?”
“Sounds like a phone ring.”

“Really, during the stream?”

Hoshi anticipated who it was. Sighing lightly, he approached Cotton Candy. Then, surprisingly… rustle, rustle.

“Woof.”

From within Cotton Candy’s fluffy fur, he pulled out a smartphone. Apparently, the little props were stored there.

“A phone came out of the fluff lol”
“It was in there the whole time? lol”
“Like a fourth-dimensional pocket lol”
“Convenient lol”

“Thought so. Sorry, please wait a moment.”

Hoshi turned away from the camera to answer the call.

“Don’t call during a stream lol”
“This is the S-rank dungeon’s deep layer, by the way.”
“Always so carefree.”

“What?”
“Hoshi-kun, aren’t you coming home yet?”
“Wait, I’m streaming right now.”

The caller was, as expected, his sister, the elf Erika.

But the conversation was not private.

“Wait, this can be heard? lol”
“Broadcasting the call lol”
“Everyone can hear it lol”
“Erika’s waiting lol”

“Really…”

Hoshi had no memory of setting this up. If anyone did, it was undoubtedly Erika’s doing.

“Really now~”

“I won’t be late.”
“It’s already late.”
“It’s just…”

He glanced at the camera, showing 7 PM.

“I’ll be back by 9 PM.”
“Today’s dinner is hamburgers.”
“—Coming right now.”

Hearing about hamburgers changed Hoshi’s expression. He quickly ended the call and prepared to return home.

For Hoshi, Erika’s hamburgers were “everything.” Hearing about them made him naturally head home, his stomach rumbling. Despite everything, he still indulged in his sister’s kindness.

Turning back to the floating camera, he had only planned to peek into the deep layers, so it was a good time to end the stream.

“Sorry, I’ve got something to do… wait, what?!”

He finally noticed the flow of comments.

“Hamburgers.”
“Cute lol”
“Loves his sister lol”
“Can’t miss that.”
“(･∀･) Grinning.”
“Looking forward to it.”
“Hoshi’s excited.”
“Like a little kid? lol”

“Why is this known…?”

“Linked through RedTooth.”
“The call was broadcast lol”
“Everyone could hear lol”
“Erika’s waiting lol”

“Such…”

Unaware of this feature, Hoshi felt embarrassed.

“Really~~!”

“Hamburgers make you hurry.”
“Erika

‘s waiting lol”
“Time for kids to go home.”
“Good kids should return early.”
“Don’t let the hamburgers get cold.”

“…Kuh!”

Feeling his face turn red, Hoshi prepared to end the stream.

“Kyu kyu!”
“Woof woof!”

Even his pets laughed as he tried to close the stream. But then, a concerning comment appeared.

“Hikari Hinata is in trouble in the S-rank dungeon’s deep layers!”
