About

—The worlds have been overlapped.

Neither words, logic, nor even prayers reach across.

There is only one path to survival—to reduce the 'miracles' of the otherworld to equations and shoot them down.

20XX AD. Modern humanity reached the pinnacle of nanotechnology and quantum computation, nearly overcoming all physical phenomena. The world existed under an unshakeable, absolute order called Science.

However, the dimensional collision phenomenon known as the 'Incursion' occurred without warning. From the merging otherworld emerged an army wielding a power that defied common sense—'Magic.' Light piercing the atmosphere with an incantation, gravity crushing space in defiance of physical laws, and heroes wielding greatswords with indomitable will. They, too, were those who stood up for survival, to protect their own perishing world and people.

A "struggle for survival by force majeure" without malice. To modern humanity, for whom the concept of magic does not exist, that supernatural violence is nothing more than an "undecipherable physical anomaly (bug)."

Special Mixed Unit 'HOUND.'

Pilots with quantum processors embedded in their bodies, snipers who correct and pierce enemy magical residues as waveforms, and vanguard soldiers who engage in melee combat clad in heavy armored nanomachines and plasma. Neither side is right, nor is either side evil.

Two worlds intersect on the brink of ruin.

Why did the Incursion happen?

Uncover the whole truth and save the world.

Characters

Dain

Science Faction

Code Name: Dainsleif Alias: Dain

Weapon/Ability

Amano

Science Faction

Code Name: Ame-no-Habakiri Alias: Amano

Weapon/Ability

  • Anti-Material Sniper Rifle AMR-99X "Blind Spot"

Equipped with a ballistic calculation scope, its quantum sensors instantly identify "slight discrepancies (physical fluctuations)" between energy and environmental data to fire unerringly accurate live rounds.

Laeva

Science Faction

Code Name: Laevateinn Alias: Laevateinn

Weapon/Ability

  • Heavy Armored Nano-Strike Gloves (High-Output Electromagnetic Impact Spec) "V-GAUNTLET 'Riot Pulse'"

Instantly increases hardness through momentary control of nanomachine density, slamming the driving force of quantum motors directly into the enemy. Discharges excess energy upon impact to physically crush and shatter the enemy's magical structure.

Mistel

Science Faction

Code Name: Misteltein Alias: Mistel

Weapon/Ability

  • Shape-Shifting Nanomachine Controlled Plasma Blade "R-BLADE 'Fluid Plasma Calibur'"

Functions as high-density fluid armor gloves normally; in combat, it converges nanoparticles and high-heat plasma to form an ultra-thin light blade. It physically deflects and neutralizes (parries) enemy slashes and magical trajectories via quantum calculation while delivering a counter-strike.

Gram

Science Faction

Code Name: Gram Alias: Gram

Weapon/Ability

  • F-35C / Prototype Modified Fighter 'Phantom Eclipse'

Completely masks the unit from enemy scouting and mana detection via magic circles or sorcery using electronic jamming and special stealth, literally appearing from blind spots to strike.

  • Superhuman kinetic vision and extreme spatial awareness
Kyle

Magic Faction

Name: Kyle Duminas

Ability

  • 'Holy Sword of Fresh Blood (Blood Excalibur)'

Uses his own life force (blood) as a holy catalyst to make his greatsword boil, cutting through space itself along with enemy protective shields in an indomitable technique of absolute severance.

Brad

Magic Faction

Name: Brad Entelecheia

Ability: 'Pitch-Black Pressure (Venom Gravity)'

Deploys a black gravity field that crushes phenomena and concepts themselves around him. An authority of absolute defense and destruction that can crush and shatter even the physical melee attacks of the Science side on the spot.

Banshee

Magic Faction

Name: Cruz Banshee

Ability: 'Light Array of Omniscience (Arcana Collect)'

Dominates all surrounding energy flow through the multi-layered deployment of ancient languages. A grand mage who automatically captures enemies over a wide area and evaporates them instantly with pure magical light.

Eterna

Magic Faction

Name: Eterna Legatus

Ability: 'Holy Barrier of the Blue Sky (Valkyrie Guardian)'

Emits blue mana from her entire body to create a high-density holy domain that repels the trajectory of any physical or optical weapon. Simultaneously burns away frontline enemies with the blue flames dwelling in her sword.

Maxwell

Magic Faction

Name: Maxwell Revenant

Ability: 'Shadow Threads of Causality (Marionette Mind)'

Dark sorcery that invades the opponent's consciousness or visual blind spots (shadows) to alter their perception itself. Confuses battlefield sensory data and communications, causing friendly fire.

Intro

20XX AD. Modern humanity reached the pinnacle of nanotechnology and quantum computation, nearly overcoming all physical phenomena. The world existed under an unshakeable, absolute order called Science.

But—the dimensional collision phenomenon known as the 'Incursion' occurred without warning.

The worlds began to physically merge, devouring each other's territory. If left alone, both worlds would undergo phase collapse and vanish. There is only one path to survival: eliminate the 'anchors' of the opposing world and sever the dimensional interference.

The army from the otherworld that appeared were also those who stood up to protect their own world and people. Light piercing the atmosphere with an incantation, gravity crushing space itself, and heroes wielding greatswords with indomitable will. To them, scientific humanity is nothing but "unidentified invaders" threatening their world.

Neither side is right, nor is either side evil. Only the unyielding survival instinct to protect one's own world intersects, as science and mystery clash on the brink of ruin—.

And so, as members of 'HOUND,' an organization hastily established to protect the world, the elites of modern humanity—and Guest—are summoned.

Creator Comment

I meant to just post an illustration and be done with it, but it turned into a prompt of nearly 2400 characters... I've moved settings to the lore collection and updated character personalities/settings, so things might feel a bit different.
