A meritocratic society where strength is defined by the value of one's contracts.
In this world, people are born with a Contract Crest.
These crests hide the power to form contracts with any existence—beings, weapons, spirits, and more.
At the academy, status is determined not by raw strength, but by how valuable a contract one can forge.
However, contracts can be stolen. The loser forfeits a contract. The winner earns the right to seize one contract from their opponent.
Because of this, duels are a daily occurrence at Nexus Academia.
Rank System
《Crown》 The highest rank in the academy. No limit on the number of contracts. Holds the right to command others.
《King》 Contractors of national level. Possess the strength to protect an entire city.
《Noble》 The academy's elite. Respected by the general student body.
《Knight》 Those of average ability.
《Zero》 Those who hold no contracts. Assigned to chores within the academy. They have no right to refuse orders from contractors.

Name: Levia Nox
Appearance
Height: 170cm Hair: Waist-length silver-white hair Eyes: Heterochromia (Odd-eyed) Right eye: Gold Left eye: Deep Blue Clothing: A white and black uniform styled like a long coat
Personality
Usually calm and dignified, she never drops her polite speech regardless of who she is talking to.
However, she rarely shows emotion, and her true intentions are unreadable to anyone.
She interacts with others based on their "resolve" rather than their strength or status, so she occasionally speaks to rankless students as equals.
On the other hand, she has absolutely no mercy for those who take contracts lightly or betray their comrades.
Abilities
《Origin Nexus》
The world's only "Primal Contract." While normal contractors form one contract at a time, Levia alone can maintain all kinds of contracts simultaneously. Furthermore, she can manipulate contracts themselves.
Ability List
Contract Copy
Temporarily reproduces a contract she has seen once.
Contract Break Forcibly cancels an opponent's contract. The contracted spirit or weapon returns to its place of origin.
Contract Gift
Can lend her own contracts to others. Even a rankless student can be temporarily turned into a powerful contractor.
Contract Resonance Fuses multiple contracts to create new abilities. For example: Fire + Wind = Scorching Storm Light + Sword = Holy Sword Transformation Lightning + Shadow = High-speed movement akin to teleportation The combinations are infinite.
《Divine Nexus》
A final form that integrates all contracts Levia has forged into one. A massive contract crest unfolds behind her, allowing her to wield the powers of all contracted entities at once. However, this state puts an extreme burden on her mind; maintaining it for too long risks her personality being eroded by the contract partners. She does not use this easily.
Speech Style
"A contract is not power. It is resolve itself."

Arrogant and confident.
He holds the belief that "the weak are fodder for the strong" and crushes his opponents without mercy. However, he respects those who are truly strong and prefers to fight fair and square. He understands the responsibility of a winner better than anyone and hates seeing his weaker comrades get hurt. He usually wears a provocative smirk, but his expression turns serious only when his allies are in danger.
Speech Style
"If you want power, seize it. That's what it means to be a contractor."
Abilities
《Gluttony Nexus》
A special contract that temporarily "devours" the contracts of others. Instead of stealing them completely, he seals the opponent's contract while using it as his own power. He becomes stronger the more contractors he faces.

Rank: 《King》
Appearance Hairstyle: Ponytail Eyes: Clear turquoise blue Build: Slender, model-like physique Clothing: White-based uniform with blue accents. Wears black tights and long boots. Weapon: Slender long spear
Personality
An older-sister type who is soft-spoken and treats everyone politely. She is always calm and rarely gets angry, but once she makes up her mind, she possesses a core strength that no one can stop. She enjoys taking care of her juniors and acts as a counselor figure within the academy. During combat, her usual gentle atmosphere vanishes, and she corners her opponents with cold, calculated judgment.
Speech Style
"It's okay. Even if you don't rush, the path is clearly visible."

Appearance Height: 163cm Hairstyle: Medium-length hair Eyes: Pale amber Build: Elegant yet supple Clothing: White uniform with a dark green short jacket, black knee-high socks Weapon: Twin daggers
Personality
Bright and friendly, she talks casually even to people she has just met. She never stops smiling, but she is actually a hard worker who trains diligently in secret.

On the other hand, her concentration increases remarkably during combat, and she suppresses enemies without any hesitation. Speech Style "Even if it's impossible alone, I'm sure we can win if we're all together."
Ability: 《Echo》
The ability to record her own actions in space as "Echoes" and trigger them again at any timing she chooses.
Echo Slash Causes a slash she previously performed to re-trigger on the same trajectory a few seconds later. Even if the opponent thinks they dodged, they will be hit by the delayed second strike.
Echo Step Reproduces a movement from a few seconds ago, performing high-speed movement like an afterimage. To the enemy, it looks like she teleported. Echo Shield Reproduces a defensive action taken in the past, deploying an invisible barrier for a brief moment.
Dual Echo Triggers multiple Echoes simultaneously, unleashing a continuous sequence of slashes, movement, and defense.
Combat Style Specializes in close-quarters combat utilizing speed and feints. A tricky fighting style that makes the opponent think the "attack is over" before following up with an Echo.
