My 'Trash Skill' Called Observer's Eye Could Actually See Everything
When new adventurers join the guild, they each receive a skill that defines their talent. Swords, magic, healing — everyone gets something cool. But Kei Kusano gets 'Observer's Eye,' and the whole guild bursts out laughing.
'Observer's Eye? You can't even fight with that, what a trash skill.' Kei gets stuck doing chores and carrying luggage while everyone else levels up. He never stops quietly observing, though.
One day, the Guild Master calls him in — not for a promotion, but to kick him out.
My 'Trash Skill' Called Observer's Eye Could Actually See Everything - Trash Skill, Above S Rank
The inquiry session ended that night, and the three of them returned to the "Weathercock Tavern."
Kei sat down on the bed by the window and looked up at the ceiling.
A stone ceiling. The lamplight flickered.
(It's over... isn't it?)
The reality of it still hadn't sunk in. Dolku being led away by guards, the moment the inquisitor withdrew the charges—it all felt hazy, like something from a dream.
From across the room, Riko let out a soft snore. She'd collapsed onto the bed and fallen asleep within minutes. Her light blue twin tails spread across the pillow.
Sophie gently held her bandaged shoulder and draped a blanket over Riko.
"...You really did move a lot today, didn't you?"
"Does your shoulder hurt?"
"I'm fine."
With just those words, Sophie looked out the window. The night of the royal capital Regnoa was bright. Magical lamps lined the stone streets, giving the city a different face than it wore during the day.
"Kei-kun."
"Yes?"
"I'm glad."
That was all. But somehow, warmth spread through the center of Kei's chest.
"...Yeah."
────
The next morning came early.
Three sharp knocks on the inn's door.
Riko opened it half-asleep, saying "Huh...?" Then, three seconds later, she let out a voice close to a scream: "Eh!?"
Standing in the hallway was a woman with perfect posture.
Mid-forties, ash-brown hair tied back, wearing a uniform with the guild's emblem. Fine wrinkles lined her eyes, but they were sharp—the bearing of a former adventurer. No sword hung at her waist, but instead she carried a thick bundle of documents under her arm.
"I am Melvina Gelt, headquarters director of the Valtheim Adventurers' Guild. I have come to formally inform Kusano Kei and the others of something."
It took a minute for all three to gather. Riko was still bleary-eyed, Sophie was pulling on her jacket, and Kei was adjusting his glasses.
Melvina bowed deeply before them.
"Regarding the irregularities at the Karren branch, I offer the guild's formal apology. The actions of former Guildmaster Dolku Heizen brought shame upon our name. The Karren branch will be dissolved and reorganized. The guild's entire audit system will be reformed going forward."
The room fell silent.
Kei couldn't say anything. Neither could Sophie.
Riko was the first to cry.
"Uuuuaaaaahhhhh!!!"
It was a loud voice. From down the hallway, someone muttered, "What's all this commotion so early?" Riko covered her face with both hands and continued crying, her shoulders shaking.
Melvina looked up. Faced with an unexpected reaction, she looked a bit troubled.
"Um, well..."
"I'm sorry!! I'm just so happy!! It's really over!!"
Sophie patted her head, saying "Good for you, Riko." Riko grabbed Sophie's sleeve while saying "Don't touch me, I'm crying!!"
Melvina looked troubled again. What was supposed to be a solemn apology had somehow turned into a comedy sketch.
Sophie looked at Kei.
"Kei-kun! We did it!"
"...Thank you very much."
"Kei-kun, you should hold your head high today!"
Kei shrank back slightly. He was embarrassed.
"Well, um..."
"Kai-kun agrees with me!"
"It's Kei, not Kai."
"Oh!! I did it again!!"
"Sophie's still getting it wrong!? This isn't the time to be crying!!"
Melvina cleared her throat quietly.
"...If I may, Kusano Kei. There is one more thing I wish to inform you of."
────
Melvina pulled a sealed envelope from her documents. A red wax seal. Next to the guild headquarters' emblem was an unfamiliar character pressed into the wax.
"This is a formal scout invitation to the S-rank promotion exam."
The three of them froze for a moment.
"...S, S-rank????"
"That's correct."
"We're going for S-rank!?!?"
Riko started running around the room. Spinning in circles, repeating "S-rank! S-rank!!" Sophie caught a table that nearly toppled over.
Sophie looked at Kei.
"Let's take it, Kei-kun... Kei-kun is right, yes?"
"Yes, that's right."
"Good. Let's take it."
Kei accepted the envelope. He felt its weight solidly in his hand.
────
The exam venue was a training grounds adjacent to the Regnoa guild headquarters.
A space enclosed by high stone walls, normally used for mock battles between adventurers. Today was different. The spectator seating—stone bleachers for watching the exam—was packed with over a hundred adventurers.
Word had spread throughout the royal capital.
"The trash skill holder is taking the S-rank exam." "The one who exposed fifteen years of corruption at the inquiry." "This will decide whether the Observer's Eye is real."
Various voices filled the space within the stone walls.
The moment Kei entered the exam area, through Sophie's Observer's Eye sharing—still streaming continuously—he could see the right end of the spectator seating.
The senior adventurers from Karren.
Nearly ten of them clustered together, watching with hard faces. Not smiling. Looking at Kei with trembling eyes. The Observer's Eye automatically picked up the information.
【Regret. Fear. Disbelief—I can read it all】
Kei said nothing. He simply walked toward the center of the exam area.
"Kei-san."
Riko lined up beside him. Sophie came to the other side. Her bandaged shoulder held straight, her golden eyes facing forward.
The three of them stood together.
────
One of the examiners stood up. A man in his fifties with an A-rank badge on his chest. His voice echoed across the grounds.
"We will now release the test monsters."
An iron gate opened.
What emerged was a gray wolf. But it was two sizes larger than a normal Greyfang. Its shoulder height exceeded a human's waist, and its fangs gleamed silver.
A Silverfang—an upper-tier variant of Greyfang. Danger level B-high.
And it wasn't alone. Two, three, four—five in total appeared on the grounds. They began circling the three, maintaining advanced coordination.
The spectator seating erupted in murmurs.
"F-five!? Not four, but five!?"
"Kei-san, I'm counting on you."
Kei adjusted his glasses once.
And then—
【《Observer's Eye》, full activation】
His vision transformed.
Red lines ran across the five Silverlangs. Weak points—the joints of their hind legs, the thin skin of their throats, the gaps in their flanks—all clearly visible. Their movement patterns predicted. Their next actions readable three seconds ahead.
And that information flowed simultaneously into Sophie's and Riko's vision.
"I can see it!!"
"Understood."
Kei gave instructions quietly. His voice was soft. But it felt like it reached directly into their minds.
"Sophie-san, two steps to the left-rear. Riko-san, in three seconds, strike the right one's throat."
Sophie moved. Two steps, precisely. At that moment, one lunged—toward the space Sophie had just vacated. It missed. As its stance crumbled, Sophie's blade struck its hind leg joint with perfect accuracy.
Clang!!
The Silverfang collapsed.
"Riko-san, now."
Light gathered in Riko's palm.
"Flare Burst—!!"
Boom!!
A ball of flame hit the designated point—the right Silverfang's throat—in one direct hit. A solid impact. The Silverfang flew backward and crashed into the stone wall.
The spectator seating fell completely silent.
No one made a sound.
────
Third, fourth, fifth—as Kei's instructions continued, Sophie's blade never missed, and Riko's flame bullets never missed.
【Target 2: Left individual, will move right in one to two seconds. Sophie-san, intercept and aim for hind leg】
【Target 3: Front individual, preparing to leap. Riko-san, advance to landing point and fire】
【Targets 4 and 5: Attempting coordinated encirclement. Both move simultaneously to divide them】
As information flowed, the two moved.
Slash!!
Boom!!
Two sounds overlapped across the grounds.
The fifth Silverfang collapsed to the ground.
The moment it did, the exam area fell completely silent.
Only the wind blew.
────
No one in the spectator seating moved for a while.
Over a hundred people stood frozen.
Then one of the examiners slowly stood up. The man in his fifties. The A-rank badge. As he rose, the other examiners rose in a chain reaction.
"...This Observer's Eye."
His voice echoed quietly across the grounds.
"It is S-rank or higher."
He paused, then continued.
"Forsena Kingdom has no precedent for an information skill of this caliber."
The murmur from the spectator seating spread like a wave.
"No precedent...?" "S-rank or higher, what does that mean?" "That trash skill..."
A voice came from the cluster on the right.
One of the senior adventurers from Karren half-collapsed from his seat, muttering.
"...That trash skill is S-rank or higher..."
His voice echoed off the stone walls, reaching the entire grounds.
Kei paused for a moment in the center of the exam area.
Behind his glasses, his deep brown eyes looked at the right end of the spectator seating just once. Then he turned his gaze forward.
"...I told you so."
It was a small voice. Not a shout. But it reached clearly through the silent grounds.
Sophie began to clap. With her bandaged shoulder, painfully, but happily.
"Kei-kun, that was cool!!"
Riko cried and laughed as she shouted.
"Seriously!! You should have said that from the start!!"
────
The three were formally registered as an S-rank team an hour later.
Melvina laid three documents on the table.
"This is the first S-rank certification by Observer's Eye in Forsena Kingdom history. It will be recorded."
Riko shouted "Our names go down in history!!!" in a voice that echoed through the room.
Sophie looked at Kei.
"I'm glad, Kei-kun."
It was a quiet voice. The Observer's Eye automatically picked up information.
【Sophie Almarea: Pulse, calm. Eye focus, directed straight at me. No lies, nothing false】
He read her the same way as when they first met. Confirming that Sophie's expression held no deception, just like that time.
Back then, Kei didn't understand why there was no deception. Trusting her had been frightening.
Now it was different.
"...Yeah."
He nodded simply.
────
At dusk, the three walked down the main street of the royal capital.
The stone pavement was dyed orange. Magical lamps began to flicker on one by one, creating a time between day and night. The sound of market shops closing. The footsteps of children running. The smell of baked bread from somewhere.
Kei suddenly stopped walking.
He looked toward the southwest.
It wasn't visible from here. But beyond that direction lay the town of Karren. The Valtheim Guild's Karren branch—now dissolved and undergoing reorganization. The building where he'd carried luggage in the mornings and wiped floors at night for three years. The place where he'd been laughed at as having a "trash skill."
Everything started there.
Everything ended there.
He wouldn't look back anymore.
What the Observer's Eye captured last was—the smiling faces of Riko and Sophie as they started bickering beside him.
"Now that we're S-rank, I think Riko should listen to what I say!"
"Why does being S-rank have anything to do with that!?"
"Because S-rank is superior!"
"That's not how it works!!"
Kei smiled softly and started walking again.
That was what he most wanted to see.
The three of them walked westward through the dusk of the royal capital.
