Philippa Hominberg had never been the type to make a fuss over birthdays. Eighteen felt like just another number, especially when the only celebration was a lukewarm slice of supermarket cake shared with her younger brother in their cramped third-floor apartment. The candle flickered weakly as she blew it out, half-wishing for something more exciting than another year of scraping by in a city that never seemed to care.
"Make a wish already," her brother muttered, mouth full of frosting.
She smirked. "Wishing for rent money doesn't count, does it?"
Before he could answer, the air changed.
A low, glass-like crack echoed from outside, not loud but wrong — like reality itself had developed a hairline fracture. Philippa stepped to the window. The evening sky over the rooftops shimmered, colors bleeding where they shouldn't. Then the first rift tore open, a jagged violet tear hanging mid-air above the street below.
People screamed.
The first monster came through fast — a twisted thing that used to be a dog, maybe, but now its body was bloated with pulsing veins and extra joints that bent the wrong way. It landed on all fours with a wet smack, claws gouging asphalt. A woman running past didn't stand a chance. The creature lunged, jaws unhinging wider than any natural mouth should. There was a sickening crunch as teeth sank into her shoulder, tearing through muscle and fabric alike. Blood sprayed in a bright arterial arc, painting the pavement crimson. Her scream cut off into a wet gurgle as the monster shook its head, ripping a chunk of flesh free. The metallic stench of hot blood drifted up even to the third floor.
Philippa's stomach lurched. "Stay inside," she snapped at her brother, already grabbing the kitchen knife from the counter. It was pathetic — a cheap serrated blade — but it was something.
Another rift split open closer, this one vomiting out smaller horrors that skittered like oversized insects with too many legs. Shouts turned to raw panic in the street. Someone tried to fight back with a metal pipe; the pipe connected with a crack against chitin, but the creature retaliated by driving a barbed limb straight through the man's thigh. The sound of meat tearing was unmistakable, followed by the heavy patter of blood hitting concrete.
Philippa's heart hammered. She wasn't a hero. She was just a girl who had learned early that waiting for help usually meant you died waiting. She bolted down the stairs, knife tight in her grip, the blade already slick with nervous sweat.
Outside, chaos reigned. The air tasted wrong — ozone mixed with copper and something sickly sweet. A larger beast, this one vaguely humanoid but with elongated arms ending in hooked talons, cornered two people against a parked car. It swiped lazily. One hook caught a man across the belly. Fabric and skin parted like wet paper. Intestines spilled out in a glistening loop, steaming in the cool night air as he collapsed, screaming until his voice gave out in a bubbling choke.
Philippa's breath came short. She couldn't freeze.
Something inside her snapped — not fear, exactly, but a desperate clarity. A blue panel flickered at the edge of her vision, translucent and cold.
[Sacrifice System Activated.]
[Host: Philippa Hominberg]
[First Offering Detected. What will you trade for survival?]
The prompt felt clinical, almost mocking in its calmness while people died screaming around her. She didn't have time to question it. The humanoid beast turned its milky eyes toward her, talons dripping.
"I don't know — a memory," she hissed under her breath, thinking of the stupidest, most useless thing she could spare: the embarrassing sting of failing her last math exam in secondary school, the way her cheeks had burned when the teacher announced the scores.
The System accepted it instantly.
A sharp tug pulled at her temple, like someone had yanked a thread loose from her brain. For a split second her vision swam, and she felt an absurd urge to laugh at how ridiculous this all was — eighteen years old and trading childhood humiliation for a fighting chance. The mild dizziness passed quickly, leaving a faint, ironic echo in her mind.
Power surged through her arms and legs, raw and unsteady. Her muscles felt tighter, reflexes sharper. She moved before she could overthink it, lunging forward with the kitchen knife.
The blade sank into the creature's side with a wet, resistant squelch. Thick, dark ichor sprayed out, hot and foul-smelling, splattering across her shirt and face. The beast roared, a sound that vibrated in her bones, and swung a taloned arm. She twisted aside — faster than she should have been — but the edge still grazed her forearm, opening a shallow gash that burned like fire. Blood welled up immediately, warm and sticky.
She yanked the knife free with a gruesome sucking sound and stabbed again, this time higher, aiming for what passed as its throat. The serrated edge caught and tore through tough hide, revealing pulsing tubes beneath. More ichor gushed, mixing with her own blood on the ground.
The creature staggered, but it wasn't down. Its remaining arm whipped around, forcing her to duck. She felt the wind of the swing ruffle her hair.

Philippa didn't have time to read the rest. The beast recovered faster than expected, lunging again with both talons raised, ready to impale her against the blood-slick pavement. Her enhanced grip tightened on the knife as she prepared to meet the charge head-on, heart pounding, the metallic taste of fear and adrenaline sharp on her tongue—
