Nyx stood alone in the desolate expanse beyond Trinity, the weight of her anguish pressing down upon her. The world around her was silent, but within, a storm raged.

"It's not fair," she whispered, her voice trembling with a mix of sorrow and fury. The injustices she had endured—the relentless jealousy from Mika, the chasm between her and Seia, the constant feeling of being an outsider—had pushed her to the brink.

Her thoughts spiraled, each one a dagger to her heart. She had only ever wanted to be close to Seia, to share in the warmth of her presence. But every attempt was met with barriers, both external and internal.

"Why is it so hard?" she cried out, her voice echoing into the void. The frustration and despair coalesced into a palpable pain, tearing at her very soul.

"I can't... I can't... I can't..." The mantra became a crescendo, each repetition amplifying her torment. The world blurred as tears streamed down her face, her vision clouded by the depth of her suffering.

In a surge of overwhelming emotion, she screamed, "I will eradicate everything!" The declaration was both a vow and a release, a culmination of the darkness that had been festering within her.

As if responding to her anguish, a bolt of red lightning struck down upon her, the ground trembling with the force of the ensuing explosion. The energy surged through her, reshaping her form and essence.

Sensei and the members of the Make-Up Work Club witnessed the cataclysmic event from a distance. Alarmed, Sensei commanded, "We need to go, now!"

Activating the Shittim Chest, Sensei reached out to Arona. "What just happened?"

Arona's voice, tinged with concern, responded, "It's a high-energy surge, linked to a being from outside Kivotos... but it's not Chroma."

Meanwhile, Mika rose with determination. "I'm going there myself."

Nagisa interjected, "We'll accompany you."

Together, Mika, Nagisa, and Seia set out, their paths converging with Sensei, Hifumi, Azusa, Koharu, and Hanako at the epicenter of the disturbance.

Koharu, spotting Mika, questioned, "Why are you here?"

Mika, urgency in her tone, replied, "There's no time for that."

Suddenly, Nyx emerged from the shadows. Her appearance was transformed: eyes glowing magenta with contracted black irises, hair radiating a luminous magenta hue, and demon horns alight. Her halo was fractured, glitching, and adorned with an inverted, cracked black heart encircled by sharp edges.

Mika's eyes widened in realization. "That structure on her halo... it was meant to prevent this."

Seia, concern evident, asked, "What do you mean?"

Mika explained, "That core would pulse with energy whenever Nyx seemed ready to fight. It was a safeguard."

Nyx stood before them, magenta flames dancing on her right hand, gripping a menacing black and magenta scythe. In her left hand, she wielded the FAMS-1V—a modified McMillan TAC-50, now transformed to mirror her altered state.

It changed, a Benelli M4, the tips turning a dark magenta hue.. Like Hoshino Terror's weapon.

Her face bore black markings, and an aura of magenta and red flames surrounded her. She stood poised, legs apart, scythe raised, as the air crackled with dark energy.

Sensei, sensing the imminent danger, shouted, "Look out!"

A massive black sphere formed at the tip of Nyx's scythe, its gravitational pull distorting the very fabric of reality.

With a deafening roar, the sphere hurtled toward them.

—BWWWWOOOMM!

Reacting swiftly, Sensei harnessed the power of the Shittim Chest to erect a protective barrier, absorbing the brunt of the attack.

Mika retaliated, firing at Nyx, but she deftly deflected the shots with her scythe, then vanished, reappearing behind Mika in an instant.

Mika narrowly evaded the strike, noting, "This isn't good. We've never faced someone with such close-combat prowess."

Nyx leveled the FAMS-1V and fired. The resulting explosion sent shockwaves through the area.

Koharu screamed, "Nyx, stop!"

But her pleas fell on deaf ears. Nyx muttered, "Eradication," repeatedly, her voice a haunting, broken whisper.

Dark spears materialized around them, poised to strike.

This was no longer the Nyx they knew.
