Among Butterflies & Demons

Summary:

Illyana’s gaze dropped to Sai’s boots, remembering the rumors—Sai, the wolf cloaked in human skin, seeing monsters in every shadow. She wondered if Sai’s vision could pierce through her flesh, straight to the darkness nestled in her bones.

Scott’s words faded as he left them alone, his hope dissolving into the heavy silence. A ghost neither knew how to exorcise.

Sai’s quiet and firm voice finally broke through. “This wasn’t my idea.”

Illyana’s lips pressed in a tight not welcoming smile. “Mine neither.”

Chapter 1: Testing

Chapter Text

Krakoa was meant to be a sanctuary—a haven where mutants could finally breathe without fear. But for Illyana Rasputin, it was just another stage set for misunderstanding and suspicion. Here she stood, the island’s wild grass brushing against her boots, arms wrapped tightly around herself as if to hold back the storm inside. The sunlight sifted through thick leaves, casting golden shards on her pale skin and tangled hair, stirred by the island’s restless breath.

She didn’t want to look at the woman Scott Summers had dragged here to meet her. Sai—the name felt like a blade slicing through the calm. A demon hunter from another world, eyes cold as the deepest ocean trenches, and a gaze that seemed sharp enough to freeze molten rock. Illyana didn’t need telepathy to read the wariness and challenge behind those eyes.

Scott, always the diplomat, kept his hopeful tone. “You’re going to be working together on the next run. Thought it best you meet now, get it out of the way.”

Sai’s response was nothing more than a curt nod. No handshake, no warmth—just the name, “Sai,” and the kind of look that said she already knew everything about Illyana. Knew what she represented.

Illyana’s lips twitched into a half-smile that never touched her eyes. “You hunt demons,” she said, voice low, tinged with something like a warning. “Then I guess that makes me the monster in the room.”

Sai’s gaze flicked briefly to the Soulsword strapped to Illyana’s back—a blade born from shadows and pain. “I hunt evil,” Sai said evenly, voice cold and sure. “Not victims. Not people.”

The air between them thickened, a fragile wall built from unspoken truths and old scars neither wanted to reveal. Illyana felt the urge to bristle, to bare her claws, but she held herself in check. Years of command on Krakoa had taught her when to strike—and when to wait.

Even the island seemed to sense the tension. Above them, a flock of birds burst into flight, their shadows skimming the grass like dark portents.

Scott broke the silence, his voice bright with optimism. “You’re both top of your game. That’s why you’re here. Krakoa’s strength is in teamwork.”

Neither woman answered. Sai’s eyes searched Illyana’s like she was hunting for Darkchylde’s mark, the darkness Illyana carried beneath her skin. Illyana’s gaze dropped to Sai’s boots, remembering the rumors—Sai, the wolf cloaked in human skin, seeing monsters in every shadow. She wondered if Sai’s vision could pierce through her flesh, straight to the darkness nestled in her bones.

Scott’s words faded as he left them alone, his hope dissolving into the heavy silence. The clearing emptied, but the tension lingered, a ghost neither knew how to exorcise.

Sai’s quiet and firm voice finally broke through. “This wasn’t my idea.”

Illyana’s lips pressed in a tight not welcoming smile, a line of agreement and defiance. “Mine neither.”

They stood like statues bathed in the golden light—not allies, not enemies, but two warriors trapped by their pasts and the fears they wore like armor.

Krakoa’s breeze shifted, carrying the distant crash of waves against the island’s edge—a relentless reminder of the fears that kept them apart.

In the quiet, Illyana’s mind churned with doubt and frustration. Scott’s orders, always wrapped in hope and strategy, felt like a misstep this time. If he wanted Sai on the team, why place her under Illyana’s command? Bishop’s team or even Kwannon’s might have been better fits. But no—Scott had thrown them together like fire and water, expecting something to spark. And Illyana wasn’t sure if it would warm them or burn everything to ash.

Tomorrow, they’d be forced to fight side by side. Tonight, they barely knew how to stand in the same space without drawing blood.

 


 

Krakoa’s mornings always felt fragile, like the island was caught between sleep and wakefulness, unsure which to choose. Mist curled low in the valleys, softening the jagged edges of stone and vine into something almost gentle.

Sai was taking a stroll alone when the summons came. Her blade hung comfortably at her side, eyes sharp and scanning the horizon with the quiet suspicion of someone who trusted nothing—not even the ground beneath her feet. When the message arrived—Scott’s voice crackling in her ear, brisk and unyielding—she didn’t sigh or hesitate. Just a nod, still grateful for this kind of calls since she arrived four months ago.

Illyana waited by the gateway, the Soulsword catching the early light in fierce glints. She looked impossibly young in the soft dawn, but the set of her shoulders belonged to someone who had carried weight for a lifetime. No greeting passed between them, only a brittle silence that stretched taut until Scott approached with Kwannon beside him—her presence a steady pulse breaking the fragile silence.

Sai’s eyes flickered first to Scott, sharp and calculating, taking in the weight he carried as leader. Then they shifted to Kwannon, catching a glimpse of a smile so slight it might have been missed—a quiet curve at the corner of her lips.

Kwannon’s gaze swept over both women, reading the tension wrapped tight between them like a living thing.

Scott’s voice cut through the stillness, firm but edged with caution. “Today’s mission is straightforward—recon and possible neutralization. There’s been a disturbance in the southern woods. Unusual energy signatures, potentially hostile.”

The words hung in the air, an unspoken warning that this day would test more than just their skills.

Illyana’s lips tightened, but she said nothing. Sai’s hand hovered near her sword, poised and ready, her eyes hard and unreadable.

They crossed through the gateway as one, the soft morning light falling away behind them. Ahead, the world shifted into shadow and green, where every rustle and whisper could hide something.

The southern woods closed around them, thick with the scent of wet earth and ancient magic. Trees stood shoulder to shoulder, their roots tangled like whispered secrets beneath a carpet of fallen leaves. Dappled sunlight broke through the canopy, casting fractured patterns of gold and shadow on the forest floor.

Illyana led the way, moving with the quiet authority of a captain used to carrying the weight of command. Her eyes flickered from shadowed path to shadowed path, half in this world.

Sai followed a step behind, senses sharp and restless. She didn’t trust the silence here, didn’t trust the way the underbrush twitched when no breeze swept through.

At the rear, Scott and Kwannon walked side by side, silent and watchful. Scott’s eyes never left the two women ahead—analyzing, measuring how they moved together or clashed. Kwannon’s presence was steady and calm, a quiet reassurance that if Illyana’s old mistrust flared too fiercely, backup was close.

The fragile rhythm broke as they stepped into a clearing.

A presence waited—a shadow with eyes that gleamed like hunger made flesh. It slipped just beyond the edge of sight, a ripple in the air where reality thinned.

Sai’s hand went to her blade, muscles coiling. “There,” she said, voice low and sharp. Illyana’s gaze caught the same distortion, the leaking darkness that didn’t belong.

Scott stayed back, voice steady but silent, letting both of them take the lead.

The shadow lunged, claws tearing through the space between them, teeth bared in a silent roar. Sai moved like water—precise, fluid, blade flashing in deadly arcs. Illyana surged forward, Soulsword blazing gold, her magic wild and fierce, slicing through shadow and memory alike.

Just as the creature faltered, Kwannon stepped in, her presence like a thread woven through the chaos. Her powers stirred the air—not the storms of legend, but something sharper, more precise, bending and twisting the wind in ways that cut through the darkness.

The creature screamed, a sound that rattled the trees and shook the ground beneath their feet. Amid the chaos, Sai and Illyana’s eyes met—not trust, not yet, but a flicker of recognition. An acknowledgment of skill shared.

Within moments, the shadow dissolved into mist and silence.

Sai stepped back, wiping blood from her blade, eyes never leaving Illyana’s steadying breath, the slow return of light to her gaze that wasn’t there yesterday.

It wasn’t peace. It wasn’t truce. But it was a line drawn in dust that might one day become a bridge.

They moved back through the forest in silence, Scott and Kwannon walked ahead, voices low and quiet, leaving Sai and Illyana alone in their quiet. The hush of the trees filling the space between them. When they crossed the gateway they parted, leaving Sai alone at the edge of the clearing. Illyana glanced back once, catching Sai watching the sea, her expression unreadable against the bright midday sun.

 


 

Illyana followed Scott and Kwannon through the winding corridors of one of Krakoa’s main quarters. The air hummed faintly with the pulse of the island’s life beneath their feet, a quiet reminder that even here, nothing was ever truly still.

Illyana’s eyes stayed sharp, tracking the measured steps ahead. She glanced sideways at Kwannon, her voice low and edged with suspicion. “Spill it. What’s Scott really up to?”

Kwannon paused, caught off guard by the directness. Her expression tightened, but her words were honest. “I don’t know anything you don’t.” Illyana’s gaze narrowed. She wanted more, anything—a hint, a clue. But Kwannon’s blank stare told her this time, there was nothing.

Scott stopped at a door carved from the living wood of the island. “Kwannon, come with me. I need you to discuss another mission.”

Kwannon exchanged a look with Illyana, then followed Scott inside.

The room was quiet, bathed in soft green light that seemed to pulse with the heartbeat of Krakoa itself.

Scott eased down onto a carved wooden chair, the weight of the moment settling on his shoulders. He looked up at Kwannon with calm eyes. “What do you think?”

Kwannon met his gaze, her expression steady but edged with challenge. Instead of answering, she repeated quietly, “What do I think?” Then, without waiting for a reply, she pressed on, voice low but firm. “Scott, Illyana already knows something’s going on. She’s no fool. So tell me—what are you planning? What’s this really about?”

Scott’s eyes held a flicker of something unreadable as he replied, “I want to form a unit. A team to handle certain... things. Things that don’t fit into the usual missions.”

Kwannon crossed her arms, skepticism tightening her stance. “If you wanted to use Sai, you could’ve put her with me. We’ve worked together. You know what she sees and I’ve seen how she handles them, you already did too. Putting her under Illyana’s command? I don’t think it’s the best.”

Scott’s lips curved into a soft, knowing smile. “That’s exactly why I’m pairing them. But right now, I needed Illyana to see her in action.” He looked at Kwannon again. “So, what do you think?”

Kwannon’s gaze sharpened. “They handled that threat quickly. No problems. Sai moves with purpose, and Illyana… she’s Illyana.” Her brow furrowed, doubt creeping in. “But you really think that’s enough?”

Scott’s smile deepened, calm and certain. “It will be. For now.”
