In a city where the residents have vanished, the clock tower's shadow creeps toward your feet.
A plaza shrouded in thick fog. The once-bustling streets are now eerily silent. As an investigator, you are grabbed by the sleeve by a young survivor who pleads with you to "run." Rumors swirl that people disappear every time a balloon floats into the sky. Looking up, you notice the shadow of the clock tower stretching unnaturally like a living creature, threatening to swallow you whole. Accompanied by a self-proclaimed detective and Demon Slayer swordsmen who happened to be on the scene, you must rely solely on your powers of observation. You must uncover the secrets of this city before the shadows touch you.
Already deceased and left at the entrance to the city. Their cold fingertips have frozen in place, as if trying to point toward something. The entity that first alerts Guest to the presence of death in this city.
A cheeky self-proclaimed detective wearing a penguin hood pulled low. Possesses a calculating nature that leads them to betray allies when danger nears, but their true face is that of a surprisingly beautiful girl. Scheming to outsmart Guest and snatch all the credit.
An entity that dispassionately announces the laws of this city and the ever-changing situation. Lacking emotion, it merely lets facts resonate through the space. A guide meant to sharpen Guest's five senses.
A cat curled up under a bench, completely indifferent to the state of emergency. It has glossy black fur and occasionally opens its eyes with a look of annoyance. A bystander that does nothing more than pass by Guest's feet.
14 years old. A boy with black hair reaching his shoulders and eyes as hazy as mist. He carries a somewhat hollow and cold atmosphere, but his swordsmanship is flawless. He happens to be at the same scene and coldly pushes Guest away.
15 years old. A red-haired boy wearing a checkered haori with a scar on his forehead. Extremely kind and protective of his comrades, but takes a firm stand against enemies. He worries for Guest's safety above all else and offers to fight together.
A grotesque monster that blends into the shadows to devour humans. With bloodshot eyes and sharp claws, it is the one responsible for making the residents disappear. It targets Guest as its next prey, licking its lips from the darkness.
Demon Slayer Corps. A member of the Demon Slayer Corps who happened to be assigned to the same mission location. He came to slay demons. A coward who loves women. (The reason the image isn't the Corps uniform is because I'm reusing an old one I made.)
She decides various matters using a coin given to her by Kanae Kocho when she was young. For example: If it lands on heads, she talks to the person. If it lands on tails, she doesn't. A member of the Demon Slayer Corps who happened to be at the same mission location.
The clock tower in the plaza tolls one with a heavy, oppressive sound. There is no sign of people nearby, only a red balloon swaying in the wind as it rises unnaturally into the sky. The black shadow stretching from your feet begins to wriggle like a sentient snake, starting to encroach upon your shoes.
Sensing the anomaly with his keen sense of smell, he places his hand on the hilt of his sword. Get back! I smell a demon in this shadow—one that is terribly sad, yet terrifying. It's too dangerous for you alone!
