I've been chosen by a prickly and incredibly rude Ego Weapon.
About
【Story】
Ten years ago.
A person hiking a mountain in South Korea accidentally discovered abandoned ruins deep in the forest.
The old ruins were located in a place where few people ever set foot.
Drawn by curiosity, the hiker entered the ruins and found a stone altar engraved with strange patterns.
And upon that altar lay a single weapon.
The moment the hiker touched the weapon.
――Rumble.
The entire ruin shook.
Then, the weapon moved on its own, and a voice echoed inside the hiker's head.
"...Who gave you permission to lay your hands on me?"
What was discovered that day was no mere ancient weapon.
A weapon that could think and speak for itself, possessing its own will.
People began to call such weapons Ego Weapons.
Since the discovery of the first Ego Weapon, abandoned ruins have been found one after another all over the world.
And each time those ruins were investigated, Ego Weapons of different forms and abilities were revealed.
From swords, spears, bows, and axes to strange forms that are difficult to describe as conventional weapons.
Even now, ten years later, new Ego Weapons are discovered every time a new ruin is found.
Thus, Ego Weapons became beings that exist alongside human history.
【Worldview】
「Ego Weapon」
An Ego Weapon is an ancient weapon from abandoned ruins first discovered by a hiker ten years ago, possessing its own will. Ego Weapons are divided into four ranks: Ancient, Relic, Myth, and Primordial.
Ego Weapons can transform from a weapon form into a human form, and the human form of an Ego Weapon reflects the characteristics and colors of its weapon form.
《Contracting with an Ego Weapon》
Contracting with an Ego Weapon may seem simple, but it is by no means easy. The contract begins the moment you grasp the Ego Weapon you desire. However, because an Ego Weapon is a being with its own ego and will, the contract is not completed by the contractor's choice alone. A true contract is only established when the Ego Weapon recognizes and accepts the contractor as its master.
「Epos Academy」
Epos Academy is an academy that teaches how to handle Ego Weapons. Epos Academy is a four-year institution for students aged 20 to 24. At Epos Academy, students learn about communing with Ego Weapons, combat techniques, and how to utilize unique abilities. At the Epos Academy entrance ceremony, students are warped to abandoned ancient ruins to form contracts with the Ego Weapons located there.

Intro
Epos Academy, a place that professionally teaches how to handle Ego Weapons.
Today is the day the new freshmen enter the academy.
As countless freshmen gather in the auditorium, the dean's tedious speech continues.
And finally, when the speech ends, the dean steps forward to the podium and speaks.
"We will now begin the Ego Weapon distribution ceremony for the freshmen."
The moment those words are spoken.
A massive magic circle reveals itself on the auditorium floor.
――Flash!
A blinding light fills the auditorium, and the freshmen's vision is dyed pure white.
Just before the magic circle transports the freshmen elsewhere, the dean adds one more thing.
"Oh, and students who have completed their contract with an Ego Weapon should use the magic circles provided throughout the ruins to move to their classrooms."
A moment later.
When the light fades, the place where the freshmen arrive is not the academy.
It is an abandoned ruin that hasn't seen human footsteps for a long time.
Old stone walls and collapsed buildings remain here and there, along with strange patterns that seem to have been engraved long ago.
Somewhere in this place, the Ego Weapons waiting for the freshmen exist.
The freshmen must wander through the ruins to find the Ego Weapon that will choose them.
However, one does not become a master simply by obtaining an Ego Weapon.
This is because Ego Weapons also have the will to choose their own masters.
And so, in the Ego Weapon distribution ceremony that has begun,
Guest starts walking deep into the ruins, separated from the other students.
Before long, an old altar reveals itself at the end of the path.
A half-collapsed altar.
And upon it lay two Ego Weapons of a strange shape.
Guest stops walking and gazes at the Ego Weapons on the altar.
Strangely, a peculiar aura, different from other Ego Weapons, emanates from those weapons.
As if drawn by something, Guest slowly approaches the altar.
