The moment Koyanskaya dispelled the Reality Marble, Sajyou Manaka vanished like a ghost. She literally disappeared—because her power instantly returned the moment Koyanskaya opened the "Tunguska Sanctuary." But this time, Sajyou Manaka didn't attack; she used her own power to move through space. Before she left, she glanced at the black-haired man, a smile spreading across her face.
"Brother, I'll definitely save you."
It was as if a wicked dragon from a fairy tale had stolen the princess, and now the author had no choice but to end the story herself. But before that, she still needed consciousness—awareness that could touch every part of her being.
Sajyou Izaya didn't get a chance to act; in the next moment, Sajyou Manaka had already used her teleportation magic to leave.
The battle died down silently, and the space fell into absolute stillness.
The air began to stir.
Sajyou Izaya looked up as if sensing something. From the start, the two Lords had been rendered speechless, and Koyanskaya also looked over. In the quiet corridor, she walked with elegance and grace, her luxurious dress blooming like a flower in the darkness. The sound of her high heels striking the floor was like a heartbeat. She ignored the stares around her, as if the prior battle had nothing to do with her. For a very long time, she simply reached out and hugged the man tightly.
"This time, I won't let go again… Izaya-kun~"
If you didn't know that this "monster" was like a ticking nuclear bomb that could explode any time, the scene would have seemed utterly enchanting.
Kayneth gazed at her beautiful, moving face and quickly recalled his earlier complaints about the student who had just bested her…
His eyelids fluttered heavily, his fingertips trembling unconsciously. When Koyanskaya once again pressed a gentle kiss to the man's lips, her soft expression gradually faded. She always wore a commercial smile in public, rarely showing her true self. But she didn't want to make too much noise at the Clock Tower either.
So Koyanskaya tilted her head with a golden-eyed glance at Kayneth and the others, smiling as usual.
"Let me reintroduce myself… Beast IV, Koyanskaya."
"I don't intend to cause trouble at the Clock Tower. I've come to seek cooperation this time… If possible, I hope you'll keep quiet about what happened today."
An eerie silence filled the air. As Lords of the Clock Tower, what grand scenes hadn't they seen before? But what happened today had exceeded all their expectations.
What was the concept of a "Beast"? Kayneth might not know, but as a Lord of the Astronomy, Marisbury understood much better. And if he wasn't mistaken, the girl just now named "Sajyou Manaka" seemed to be a Beast as well.
The two of them stared at her as if hypnotized. Gazing at the mature and seductive "Beast of Cherishment" who could destroy the world, neither the arrogant Kayneth nor Marisbury hesitated to nod. The battle they'd just witnessed had seemed like a clash between gods—they desperately wanted to end this terrifying conversation.
…
Time passed quickly, and two days slipped by unnoticed.
The clash between Koyanskaya and Sajyou Manaka didn't cause as much of a stir as one might expect… To be precise, Kayneth and Marisbury had quietly smoothed things over afterward.
At Sajyou Izaya's dormitory, the air was thick with a certain intimate tension.
"But I don't think you've explained yet, have you? How have you lived from 1908 until now… Are you a vampire, perhaps?"
Hearing Koyanskaya's question, Sajyou Izaya wrapped his arms around her waist and muttered,
"It's a long story…"
"If you don't want to say, forget it. Everybody has their secrets, I understand."
Koyanskaya looked down with a slightly contented monotone, gently caressing the man's face with her white fingers.
"Are you thinking of something else?"
"I can't calculate it… I have no idea where Manaka went—"
As he finished speaking, Koyanskaya suddenly tensed, making Sajyou Izaya's hold on her waist loosen a bit.
It was obvious Izaya liked Manaka… Or was the appearance of his fiancée the trigger for Koyanskaya's accelerated attack…?
Gripping Koyanskaya's seductive, serpentine waist, Sajyou Izaya looked into her eyes and suddenly asked,
"Can you feel the dark Koyanskaya now?"
But she averted her gaze in guilt, not answering.
…Is it difficult now…? Is she the dark Koyanskaya? On the surface they looked the same, but on closer inspection, her hair color seemed to have changed from pink to gold… and even her temperament was different from the current light Koyanskaya. In a sense, they were now a single body with two souls, able to change forms at will. One was charming and gentle; the other, cold and arrogant—completely different personalities. Marrying one was like marrying two wives at once… What a bargain.
"That girl is dangerous."
"If my guess is right, she's preparing a plan to reclaim her 'prince.'"
The next moment, Koyanskaya's hair color shifted to a cherry blossom pink, swaying freely. She hugged Sajyou Izaya's neck tightly and exhaled softly into his ear. Looking at Koyanskaya's seductive smile and air of total control, Sajyou Izaya realized something faintly.
"Do you know where she is?"
"I can probably guess… Hmm~"
She looked at him with a mixture of longing and charm.
"She's connected to the Root, but at her core, she's a candidate qualified to become a Beast—a very unstable young Beast."
Every action Sajyou Manaka takes is pure, arising from her "love" for Sajyou Izaya. But because of Koyanskaya's existence, this pure love is now mixed with N.T.R. elements… Her script was broken, and she herself was defeated… To become stronger and avoid her brother's "corrupted" fate, she needed more power.
"She wants to become a true Beast?"
Sajyou Izaya blurted out.
"You're so smart, Izaya-kun~" Koyanskaya gently cupped the man's face. "To become complete, she needs a stage and a sacrifice… Guess where she is now?"
Looking at that captivatingly flushed face, Sajyou Izaya had a faint realization.
"Fuyuki City?"
….
In FGO, Dark Koyanskaya is Foreigner-class Servant while Light Koyanskaya is Assassin-class Servant.
