Through the Glass: The Ruins Experiment Arc
The story starts late at night. Bells echo through the Southside. Only rats and tired workers are still walking under pale yellow streetlights. Haruka Seno, our lead, wakes up sweating after fever dreams. Her hand still aches, ghost pain crawling along the old scar left four years ago. Why did it hurt now? Is there something she’s forgetting?
By morning, she meets Kaito, her best friend, who comes with news. “They found a body by the river. Same marks, same as the ones that vanished back then. You know, the ones the city never talked about?” The words hit her like cold rain. He looks haunted, worried. Haruka can’t hide how it shakes her—she remembers each detail way too well. Have you ever felt your old wounds open like they knew a storm was near?
The two head to school, but everyone is tense and looking over their shoulders. Touko, the new transfer, is absent. She was seen last night near the ruins, Kaito whispers. “Look—I know it sounds wild, but that building, the old glass clinic, it’s not empty. People have heard noises. You heard it too, right, Seno?”
That evening, Haruka can’t rest. Moonlight drags long shadows across her room. Whispers echo inside her head. She decides to return to where the marks came from—the old glass-walled hospital where their town’s darkest rumors root. The place is chained shut, spiderwebs thick in the windows. Broken charms line the gate. She breaks in, cold breath swirling, her pulse rising at each step inside.
In the main hall, she finds diagrams scratched in blood onto tile. Haruka’s eyes follow strange shapes—a circle with four spikes, a string of numbers she’s learned to fear. Kaito, against her pleas, slips in too, drawn in by the odd noise. They creep deep into the halls, panic clawing inside their chests. You know the feel, don’t you? When silence gets loud. 
Soon, they spot strange figures. There’s a child in a hospital gown with empty eyes—she twitches, muttering backwards phrases. In another wing, half-done drawings shiver along the walls, as if dancing when her back is turned. Is this real, or some cruel trick? Deep below, eerie blue light flickers and fades.
Suddenly, a woman in sharp-cornered black and white appears. Dr. Ushio Mori. Tongue cold as icewater, eyes empty of care. She marks her notebook. “Curious,” Dr. Mori whispers, “That wound of yours, Haruka. Still there? How pliant young subjects can be.” Anger boils in Haruka’s gut. She’d heard Dr. Mori’s voice years ago, after she woke in a cold metal room. Now the doctor is back—testing limits again. Do you trust those in power to do the right thing if it means breaking some people along the way?
Kaito tries to step between them, but a heavy metal door slams shut. Gas fills the hall—misty, pale blue. Pain claws at Haruka’s scar, making her drop to her knees. Dr. Mori crouches, smiling. “Side effects of the Ruins Treatment: waking relics in our testbed. You kept side five alive long enough for data. Let’s see if you’ll last a second trial.” 
The experiment restarts. The walls close in, filled with ghost lights and half-remembered screams. But this time, Haruka fights. She claws at the tiled floor. She begs Kaito, “If you run, you’re safe. Please, just go!” Kaito shakes his head. “I don’t leave my friends.”
Barely clinging to wakefulness, Haruka sees a flash. Toko—the missing girl—appears pale, wide-eyed. But whose side is she on? Some marks are fresh on her arms, shapes the same as Haruka’s scar. The doctor stands between past and present, grinning at the future.
The arc closes on a sharp cliffhanger: The experiment’s results spike. Lights hum and black water spills across the lab’s panels. As glass bursts high overhead and wind howls inside, Haruka reaches for Kaito—but a cold hand drags her down. Are some wounds too deep to heal?
The screen cuts to black, sirens wailing, while the blue light pounds and fades.
