This intro unfolds from Ayatsuno Yuni's perspective. For those who find the intro too long to read, a 3-line summary is provided at the very bottom.

🎵 Sub Urban - Cradles.

I rubbed the spot where she had been, as if unable to believe she was gone. 'The Greatest Imperial Princess', Airi Kanna—the Constellation who had been protecting the Nebula <StelLive> until just a moment ago, my comrade with whom I shared life and death—was nowhere to be seen.

[The Constellation, 'Unicorn Upon the Sea', looks up at the empty sky.]

No voice came out. My fingertips trembled. In the place where warmth had remained just a moment ago, there was now nothing. I collapsed to my knees. My fingernails broke as they scratched the ground, but I felt no pain. Instead, from the center of my chest, I heard the sound of something cracking very slowly.

[The Legend-grade fable, 'Comrades Sharing Life and Death', is horribly twisted.]

That old fable connected to Kanna was groaning as if it had been crushed. It wasn't completely severed. But every time I felt that faint vibration, I felt myself sinking further into something. Being alive didn't feel like a comfort; it felt like proof that I had driven her into such a state.

I raised my head. The surroundings were more cruel than anything else. Sakihane Fuya was covered in wounds while blocking the attacks of the Constellations, Shirayuki Hina fought while leaking fables like a broken doll, and Arahashi Tabi lay collapsed with her eyes closed. Hanako Nana was fighting somehow with her one remaining Kruger pistol, and Neneko Mashiro... I couldn't bring myself to look in that direction.

Every time I took in each person's name, something crumbled away bit by bit. It wasn't sadness. It was an irreversible condemnation directed at myself. And above that misery, a cheer was heard from afar.

[The disaster has been removed!] [We have finally brought that dangerous Nebula to its knees!]

[The Constellation, 'Unicorn Upon the Sea', hears that cheer.]

They were laughing. They were laughing. Even as those laughs pierced my ears, I was blaming myself before I could resent them. Me, who held the title of representative but couldn't protect a single thing.

[The Constellation, 'Unicorn Upon the Sea', is consumed by deep guilt toward herself.]

「It was a silent collapse. On the outside, she was just a motionless Constellation on her knees, but inside, even the last bit of faith in herself was being crushed by her own hands.」

Not even tears would come. I thought I didn't even have the right to be sad. Something I could hardly feel was splitting my heart, telling me everything was my fault.

「If I kill all those Constellations.」

That one sentence was the only thing clear in my empty heart. It felt like I could hear a clear, beautiful voice that shouldn't be heard.

「If I kill them all so they can't be hurt.」

[The Legend-grade fable, 'Destruction of Purity', begins to react to the owner's twisted heart.]

The guilt of failing to protect began to change its form into something else from that moment. The heart that could not forgive itself soon hardened into a cold resolve toward this entire world. If it's something that could be even a slight threat, I must eliminate it in advance. Only then will I never have to feel this guilt again.

[The Legend-grade fable, 'Destruction of Purity', is completely corrupted.]

[The Legend-grade fable, 'Comrades Sharing Life and Death', screams in pain.]

「No one reached out to her. No one tempted her. She simply collapsed alone and twisted alone within the unforgiven guilt toward herself.」

「The star that shone the brightest fell by its own hand, unable to endure its own light.」

I slowly stood up atop the debris of the battlefield. Dried tears tickled me. In their place, only a twisted resolve never to feel this guilt again sat coldly.

[The Constellation, 'Unicorn Upon the Sea', twists her own modifier!]

This was a completely new story.

「The morning star that shone brighter than anyone else fell into its own light, unable to forgive itself.」

[The Constellation, 'Fallen Archangel', slowly opens her eyes.]

From afar, I heard the mocking voices of the Constellations looking at me. Seeing the eyes of those who had no idea what fate they were about to face, murderous intent surged within me.

Airi Kanna had once told all the Constellations of <StelLive> in the past not to hate the other Constellations. She used to tell me this: since our growth rate is so fast, it's only natural for them to be wary.

Even so, I found it hard to understand. Those constellations were so jealous of Airi Kanna, who was my comrade and my everything, and because of that, I was always worried.

I thought everything would flow quite smoothly. I thought at least I wouldn't lose anyone else here. I thought I would cherish them dearly, and for them, I had steadily accumulated fables.

And yet, this is the result.

The Nebula <StelLive>, excluding myself, was designated as a disaster by those things, and as a result, most of the Constellations of <StelLive> were seriously injured and collapsed.

I will drop all those damn stars. Starting from one, I will drop dozens, hundreds of constellations. All of them. Just all of them.

I want to kill them.

[The Legend-grade fable, 'Unicorn's Wings', begins its story!]

My wings were stained blood-red and began to look like a Heavenly Horse. The unicorn's horn had completely faded to red, and dark red wings were leaking demonic energy. One thing was certain: I was far removed from the version of me they knew.

[The Legend-grade fable, 'Unicorn's Wings', takes its complete form!]

The moment the blood-red wings spread and soared into the sky, the heavens fluctuated as if splitting apart. The laughter of the Constellations who were mocking me faltered for the first time.

[...W-what is that?]

Someone's voice trembled. It was a familiar face. Just a few days ago, it was the one who had smiled while offering congratulations to Airi Kanna. That day's smile and that expression now did not look like the same face to me.

[The Constellation, 'Unicorn Upon the Sea', looks down at all the Constellations on the ground.]

Strangely, my heart was very calm. The guilt and sadness that were swallowing me just a moment ago were no longer felt. In their place, only a hollow certainty remained. This wasn't anger. If it were anger, it might have been better. This was something colder and clearer than that.

[Kanna...]

I called that name one last time. No answer came back. Instead, the twisted fable beneath my feet cried low as if in response.

[The Legend-grade fable, 'Comrades Sharing Life and Death', resonates with the owner's resolve.]

[The Constellation, 'Unicorn Upon the Sea', takes a step.]

One step. The ground cracked. Two steps. The cheers of the Constellations filling the sky instantly began to turn into screams. Those mouths that were laughing and pointing at me were now saying something else.

[R-run! That's not the form of the original Constellation!] [Damn it, the unicorn's 'Corruption' has progressed!]

Too late. I was already walking into their midst.

[The Constellation, 'Fallen Archangel', smiles as if intrigued.]

From afar, someone was looking down at all of this. I hadn't noticed that gaze yet. Only the things in front of my eyes were visible. The beings standing disgustingly before me. I will drop every single one of these damn constellations.

[The Control Bureau, 'CHZZK', changes the scenario!]
