Ritsuka X Semiramis Fanfiction

The moment Semiramis descended upon Chaldea in a swirl of perfumed shadow and velvet venom, Ritsuka Fujimaru felt something shift. She was not a typical Servant. There was no timid loyalty, no quiet affection. She carried herself like a queen, and not just by title her gaze weighed judgment, her voice curled with poison, and her elegance masked a terrifying strength. Yet, within that overwhelming presence, Ritsuka sensed something deeper. Something fragile. Something that, if reached, could change both of them.

The Meeting of Poison and Innocence

Ritsuka wasn’t new to odd relationships with Servants. His path had been anything but ordinary since becoming a Master. Still, there was something about Semiramis that tested his composure. Unlike Mash, who supported him like a sister, or other heroic spirits who saw him as a leader or comrade, Semiramis looked at him like a game. Or worse like a pet.

Their first conversation had been less than ideal.

So… you’re the Master? she had said, her crimson lips curled in amusement. Chaldea truly has fallen if they hand control to children.

He’d answered with the same calm he’d offered Gilgamesh and King Hassan: And yet here you are, answering my summon.

That had caught her attention.

A Dangerous Bond Begins

Semiramis, Assassin of Red, poison queen, sovereign of floating palaces she wasn’t one to bow easily. Yet, something about Ritsuka’s unwavering spirit intrigued her. He wasn’t powerful in the traditional sense, but he endured. He led. And though her every instinct told her to manipulate or dominate, she found herself… curious.

In missions, she was ruthless. Her poisons crippled enemies before they could strike, and her silent flight above the battlefield gave her the illusion of omnipotence. Yet Ritsuka never treated her like a weapon. He thanked her. Consulted her. Sometimes even teased her.

  • You know, you could smile once in a while. It wouldn’t kill you.
  • My smile kills far more efficiently than my blade, Fujimaru.

Still, he made her laugh. Quietly. In ways she didn’t understand.

Moments in the Garden

Chaldea’s private garden what remained of it became their meeting ground. She would sit near the roses, hands stained with alchemical extracts, and he would appear with two cups of tea. She never asked for his company, but she never sent him away either.

One day, he asked the question she had dreaded and hoped for all at once.

Semiramis… before all this, before poison and throne, were you ever happy?

She didn’t answer right away. The silence stretched until the sun dipped low. When she finally spoke, her voice was hollow but soft.

Happiness is an illusion meant for fools and children. I chose power.

He nodded, then smiled gently. Maybe. But even a queen deserves a moment of peace.

She scoffed, but the cup of tea in her hand didn’t tremble. She drank it slowly.

Conflicted Emotions

Semiramis found herself watching him when he wasn’t looking. In battle, she shielded him without realizing it. During meetings, she stood closer than she needed to. When he smiled at her, her carefully constructed armor flickered only for a second, but it was enough to shake her.

He never forced anything. Never demanded affection. That frustrated her most. She was used to being desired, feared, chased. But Ritsuka treated her as an equal. Sometimes even as something… delicate.

You think I’m breakable, Master? she asked once, standing behind him, her breath cold against his ear.

No, he replied without turning. But even steel cracks when it’s always alone.

She didn’t sleep that night.

A Threat to Everything

During a lostbelt crisis, Semiramis was nearly lost. Infiltrating a corrupted realm, she had been separated, trapped behind a dimensional barrier. For three days, Ritsuka fought through wave after wave to reach her. When he found her, unconscious but alive, something inside him cracked.

He didn’t care who was watching. He held her. Whispered her name. For the first time, he allowed fear to show.

When she awoke, she found him asleep at her bedside. Fingers still curled around her gloved hand.

Idiot, she whispered, brushing his hair back. Why are you this kind?

The Confession

Weeks passed. The mission ended. Life at Chaldea returned to its odd rhythm. But something had changed between them. Semiramis grew more open, more reflective. Ritsuka more vulnerable around her. They weren’t lovers yet not in the physical sense but their bond had deepened into something sacred.

One evening, standing on the observation deck, she finally turned to him.

Fujimaru. If I said I wanted to claim you not as a servant, but as a queen claims her equal what would you say?

He met her gaze without hesitation. I’d say I’ve already chosen you.

She smiled. Genuinely. The stars behind her flared, and the queen of poisons felt something she hadn’t in centuries: warmth.

The Future They Can Never Have

They both knew their time was limited. Servants fade. Chaldea’s war may end. Reality may reset. But they clung to each moment, each mission, each quiet evening in the garden like it was eternal.

She once asked him what he’d do if she disappeared one day.

I’d grieve, he said honestly. Then I’d fight to summon you again. As many times as it takes.

Semiramis didn’t reply. She simply leaned against him, her gloved hand resting lightly over his heart. Her poison would never harm him. Not now. Not ever.

A Love Written in Shadows

They were never meant to fall in love Master and Servant, mortal and spirit, innocence and venom. But love doesn’t care for rules. Between fleeting battles and quiet nights, they found something neither of them expected. Not conquest. Not salvation. But each other.

And in the world of Chaldea, where time itself twists and destiny is always uncertain, that was more than enough.
