Introduction

Only I Can Enter the Hidden Dungeon follows the journey of Noir Starga, the third son of a minor noble family whose life changes after he discovers a mysterious hidden dungeon that grants him forbidden abilities. Noir is not blessed with social status, strength, wealth, or influence. Yet, through grit, strategic thinking, and emotional connections with the people around him, he gradually climbs from a powerless boy to a skilled adventurer.

What makes Noir different from typical fantasy protagonists is not brute strength — it's his ability to create, edit, and customize skills using LP (Life Points), earned through pleasure and positive emotional experiences. This unique system fuels both comedic moments and serious power-ups, blending humor, action, and adventure into a single entertaining storyline.

Storyline Breakdown

Noir Loses His Job and Risks His Future

Noir Starga works at a small library, his only source of income. But when the Viscount’s spoiled son demands his position, Noir is fired instantly due to his low social status.

His family’s standing is too weak to protest. Noir’s sister suggests he enroll in the Hero Academy, a prestigious institution that guarantees future stability. But Noir lacks money, skills, and power — leaving him with almost no hope of getting accepted.

This moment becomes the catalyst that pushes Noir into a new life path.

Emma and the Painful Secret of the Great Sage

Noir’s childhood friend, Emma Brightness, reveals that he possesses a rare ability:
The Great Sage — a power that grants instant knowledge, analysis, and answers.

The catch?
Summoning the Great Sage causes intense, unbearable headaches, rendering the ability nearly useless.

But Emma remembers the ancient method used by the previous Great Sage. When Noir is suffering, she kisses him — and the pain disappears instantly.

This comedic but heartfelt bond becomes one of Noir’s primary sources of LP and emotional strength.

The Great Sage’s Guidance: Find the Hidden Dungeon

When Noir summons the Great Sage again, it reveals the location of a hidden dungeon sealed away for centuries — one that only Noir can access.

This secret dungeon contains powerful treasures, dangerous monsters, and most importantly…
a chained woman waiting for someone worthy to inherit her abilities.

Thus begins Noir’s destiny-changing exploration.

Meeting Olivia — The Chained Great Adventurer

Deep inside the dungeon, Noir finds Olivia Servant, an immortal adventurer bound by magical chains for over 200 years.

Unable to move or escape, she begs Noir for company and conversation — the first she’s had in centuries.

Moved by her situation, Noir accepts her bargain:

She gives him three legendary skills:

Create – The power to create new skills
Edit – The ability to modify existing skills
Bestow – The ability to grant skills to others

These abilities make Noir uniquely powerful, but using them requires LP — Life Points.

LP increases through pleasure, happiness, excitement, or intimate interactions, adding both comedy and strategy to Noir’s journey.

LP Experiments and Academy Preparations

Noir learns how LP works:

Touching Emma gives him LP
Hugging his little sister boosts it
Emotional moments add LP
Romantic encounters add even more

He quickly discovers the cost of misusing Edit when he accidentally enlarges Emma’s heart (emotionally), then wastes LP fixing it.

With LP now essential to survival and skill development, Noir begins training to enter the Hero Academy.

Hero Academy Enrollment and First Team-Up

Despite his weak status, Noir joins the Hero Academy entrance trials. He is mocked for being a "low noble" with no talent.

Emma quits her job so she can support Noir at the academy. They soon team up with Leonora, forming a group of reliable companions.

Together, they accept a mission to collect materials from a dungeon — Noir’s first real step as an adventurer.

Defeating the Dead Reaper — Noir’s First Major Power-Up

During the mission, the group encounters a terrifying monster:
The Dead Reaper, a high-level undead creature far above Noir’s rank.

But Noir, using clever strategy, his sword skills, and Olivia’s teachings, manages to kill it.
This skyrockets his level, making him strong enough to qualify for the academy.

It’s the first moment the world realizes Noir is not ordinary.

Winning the Entrance Exam

The group presents the Dead Reaper’s skull — something no first-year team has ever done.

Their score reaches historical records, but the academy demands a huge tuition fee.

Noir needs money, and he needs it fast.

Joining the Adventurer’s Guild — Meeting Lola

Olivia advises Noir to earn money by registering at the Adventurer’s Guild.

There, he meets Lola, the friendly (and competitive) receptionist. She quickly becomes interested in Noir — professionally and personally — and helps him obtain missions.

She gives him his first paying quest:
Catching rainbow grasshoppers.

Grasshopper Hunt and Lola’s LP Boost

Noir summons the Great Sage to locate the rainbow grasshoppers. The headaches hit hard, and Emma kisses him again to heal him.

The two gather the insects and return to Lola, who—after losing a bet—playfully lifts her skirt slightly. Noir gains a massive LP boost from the sight alone, increasing his ability to create and edit skills.

The rivalry between Emma and Lola officially begins.

Jealous Emma and the Next Mission

Emma becomes jealous of Lola’s flirtation but still focuses on helping Noir earn more tuition money. She suggests they hunt a rare rabbit monster.

The team proceeds to a dangerous forest to find it.

Rabbit Fight — Emma’s Major Power-Up

While fighting goblins, a giant rabbit attacks Emma. She struggles against it until Noir gives her an LP boost in a comedic but effective way:
nibbling her ear to stimulate her LP gain.

Powered up, Emma defeats the rabbit with a beautifully animated finishing blow.

Dimensional Pocket and Tuition Victory

Noir uses Edit to create a new skill:
Dimensional Pocket — a space where he can store anything.

He stores the rabbit, turns it in, and earns enough money to pay his academy tuition.

The group celebrates, but new challenges await.

Discovering Maria’s Curse

At the academy, Noir meets Maria, the Duke’s elegant daughter. Using Analytical Eye, he discovers she suffers from a deadly curse that will kill her on her 16th birthday.

Noir immediately decides to save her.

Teacher Elna and Noir’s New Combat Skill

Noir meets Professor Elna, an extremely strong and slightly chaotic instructor. She challenges him to a retreat technique duel.

Using Edit and some LP, Noir masters the technique and impresses Elna, earning a special reward and respect from his classmates.

Maria’s Kindness and Noir’s Determination

Maria pairs with Noir during an exercise and pretends to fall into him — a mix of charm and accidental intimacy. Noir understands her situation and vows to break her curse no matter the cost.

Seeking Luna — The Healer with a Tragic Secret

Noir visits Luna, a cleric gifted with curse-removal magic but cursed with a cost:
Each time she removes a curse, her lifespan shortens.

Luna cannot save Maria without sacrificing her own life — repeating her mother’s tragic fate.

Olivia tells Noir about a technique to rapidly generate LP through comedic “lucky pervert” accidents.

Luna’s Painful Dilemma — Noir’s Brilliant Solution

Noir learns he can modify Luna’s skill so it consumes money instead of lifespan — but requires a mountain of LP.

The race to gather LP and money begins.

Pride Day Festival — A Comedic but Profitable Solution

Lola suggests entering Pride Day of Aaron, where men show off their girlfriends for prize money.

Noir and all the girls participate, each “showing off” in comedic, wholesome, and romantic ways.

They win the top prize.

Now Noir has enough money — and LP — to change Luna’s skill.

Saving Maria — Noir’s Greatest Achievement So Far

Maria’s curse reaches its final stage. Noir rushes in:

He rewrites Luna’s curse-removal skill
Luna performs the ritual
Noir uses his LP to stabilize the process

Maria confesses her feelings to Noir and kisses him — giving him a final LP surge.

The curse shatters.
Maria is saved.

The Duke rewards Noir and the girls with 100 million rels each.

New Feelings and New Wealth

Emma, Lola, and Luna all realize they have growing romantic feelings for Noir. Noir entrusts his mother with the money to avoid temptation.

But Noir wants more than money — he wants to grow stronger.

Opening a Store and New Dungeon Exploration

Noir decides to open a monster-material store and continues dungeon exploration to improve his combat abilities.

Inside the dungeon, he meets a mystical beast that changes everything...

Meeting Tigerson and Saving Buckle

Deeper inside the Hidden Dungeon, Noir encounters Tigerson, a massive black lion monster with intelligence and emotion far beyond ordinary beasts.

Instead of attacking, Tigerson pleads for help:
Its best friend, an elf named Buckle, has gone missing inside the dungeon.

Moved by Tigerson’s devotion, Noir follows him to the sixth floor, discovering Buckle transformed into a zombie by a cursed trap.

Using LP and his Edit skill, Noir removes the curse, restoring Buckle’s body and mind. The reunion between Buckle and Tigerson is heartfelt and emotional — even Noir is touched.

But Buckle cannot remain. His homeland rejects non-elves, forcing him to leave Tigerson behind.

Their farewell is sad but noble.

Seeing Tigerson’s loneliness, Noir suggests something unexpected:

“If you want, you can be my friend… and my guardian.”

Tigerson accepts.
The legendary black lion becomes Noir’s loyal companion.

A New Protector and Growing Confidence

With Tigerson by his side, Noir gains:

A powerful ally
A respected presence in the adventurer community
A guardian beast that boosts his reputation immensely

This companionship becomes one of Noir’s biggest advantages going forward.

Academy Exam and Guild Turmoil — The Lola vs. Sarah Feud

Back at the Academy, students are required to collect rare monster materials for their practical exam.

Noir and Emma head to the Adventurer’s Guild to seek help.

Here, they witness a heated argument:

Lola vs. Sarah, two rival receptionists, fighting over adventurers to boost their personal ranking inside the guild.

Sarah claims Noir as her client, trying to steal him from Lola.
Lola desperately clings to Noir, both professionally and emotionally.

The rivalry escalates into a wager:

Whichever receptionist provides stronger support to Noir’s party wins.

Thus begins the competition that pushes Noir toward his biggest challenge yet — the dragon mission.

Preparing for the Dragon Mission

To beat Sarah in the receptionist duel, Lola assigns Noir high-level missions.

Noir, Lola, Luna, Emma, and Tigerson complete several quests, gaining experience and materials.

But the final exam requires something truly rare:

Dragon materials.

A dragon is terrorizing a region, and Lola insists that defeating it will guarantee their victory.

Only the best adventurers dare fight a dragon, but Noir’s team is ready.

Tigerson Arrives at the Guild — and Trouble Follows

Tigerson enters the guild unexpectedly, drawing awe and fear from everyone present.

Sarah, trying to steal Tigerson from Noir, seduces the lion using her “charm tactics.”
Tigerson collapses to its knees, overwhelmed by a strange magical influence.

Noir immediately intervenes, cleansing the malicious energy with his Edit skill.

Tigerson recovers.

Then, Tigerson reveals a powerful secret technique:

Dragon Roar Paralysis

A roar capable of freezing a dragon in place for 30 seconds, giving Noir the perfect opportunity to attack.

Noir uses Analytical Eye to confirm the technique’s authenticity.

This becomes the key to their upcoming battle.

The Dragon Battle — Noir’s Greatest Fight So Far

The next day, Noir’s team arrives at the dragon’s lair:

The sky darkens
The ground vibrates
The beast awakens

A massive fire-breathing dragon emerges.

Weak Points Identified:

Belly
Tail
Head (requires high precision)

Noir and Tigerson charge in together:

Tigerson uses the 30-second Dragon Roar paralysis.
Noir fires Stone Bullet directly into the dragon’s vulnerable belly.
The dragon breaks free and counterattacks with a devastating fire breath.
Noir uses Stone Shield, which shatters from the impact.
Luna and Lola rush to heal him.
Emma launches a powerful Wind Strike, creating a tornado.
Noir edits a new spell: Flame Arrow, channeling all his LP.

The Flame Arrow pierces the dragon’s skull.

The dragon collapses.

The entire team celebrates — it is their biggest victory yet.

Noir collects the required materials.

Passing the Exam With Flying Colors

Back at the Academy, the students present their materials.

When Noir’s group reveals dragon parts, the entire class is shocked.
Professor Elna is speechless, impressed beyond words.

Noir’s team scores the highest marks possible, officially passing the exam.

Rising as Renowned Adventurers

Noir, Emma, and Lola continue taking high-level missions. Their teamwork becomes known throughout the guild.

People start referring to Noir as:

“The Hidden Dungeon Prodigy.”
“The Successor of Olivia.”
“The Boy With Limitless Potential.”

Noir reflects on how far he has come —
from a powerless noble son
to a powerful adventurer surrounded by loyal companions.
