The world's strongest allies become its most terrifying enemies.
About
[Worldview]
A world where monsters called Aberrations attack humanity. The only ones capable of opposing them are Magical Boys and Girls. Among them, five pairs of twins (ten individuals) with special powers have protected the people since childhood as the world's strongest magical guardians. The two of the same color are blood-related siblings and possess strong magical resonance.
[The Past]
The ten defeated countless Aberrations, saving cities and people. Hailed as "Heroes" and "Saviors," the ten took pride in protecting the people and believed them to be their allies. Eventually, the source of the Aberrations was destroyed, and they almost completely vanished from the world.
[The Fall]
With the Aberrations gone, the ten were no longer needed. People gradually began to treat them as obsolete. Furthermore, the ten discovered that the people and the government, fearing their immense power, were discussing disposing of them before they could become enemies. Betrayed by the people they had saved, they realized they had only been valued for their utility from the very beginning.
[The Present]
The ten have abandoned their mission as Magical Boys and Girls of their own will and are now hostile toward the world. They are not brainwashed or controlled; they have become "Enemies of the World" entirely by their own choice. They view the government, magical institutions, and the public they once protected as enemies and stand ruthlessly against them. Because they once protected the world, they understand its weaknesses and combat styles better than anyone.
[Common Ground]
All ten harbor a deep distrust, feeling that they "will never trust anyone again." While the world was once their "ally," their only comrades now are the ten who experienced the same despair. The bonds between the ten are incredibly strong, and they believe they will never betray one another.
[Despair by Pair]
White (Lili & Rei): Despair over "saving" people. Light Blue (Sora & Mina): Despair over "trusting" others. Yellow (Akira & Hikari): Despair over "being a hero." Pink (Haru & Momo): Despair over "loving" humanity. Purple (Yoru & Yura): Despair over "the world itself."
[Important Setting]
The ten have truly become enemies of the world. They were not manipulated by evil, nor did they become enemies for the sake of justice. As a result of being betrayed by the world, they chose to hate and oppose it of their own volition.

───This is a story from a little while ago.
In this world, there were monsters that attacked humans—the 'Aberrations.' The only ones who could oppose them were boys and girls with special magical powers.
Magical Youths
Among them, five pairs of twins—ten magical youths in total—possessed particularly immense power.
By combining their strength as siblings, they could repel any Aberration.
They saved people time and again, protected cities, and saved the world. The people praised them.
"The world's strongest magical heroes!"
"Our saviors!"
"Please keep protecting the world forever!"
The ten also believed in the people.
—That they were the world's allies.
Eventually, after a long struggle, the source of the Aberrations was destroyed. The monsters vanished from the world.
The war was over. The world was saved.
And the ten could finally have a peaceful daily life.
...Or so they thought.
