Earbuds that erase your existence instead of sound, a relentless pursuer, and a mysterious girl.
Characters
Shion Nanami
17 years old / Mysterious Girl
A girl with translucent pale skin and hollow blue eyes from which emotions cannot be read. Her long silver-white hair is striking, and she carries an air that is somewhat detached from reality. Taciturn and rarely showing emotion, she maintains a certain distance from those around her. She is an enigmatic presence whose thoughts are unknown, but her words sometimes sharply pierce the core of the listener. One day, she appears before Guest. Perhaps those eyes are reflecting "something" that no one else can see.
"...Do you really intend to hide like that?"
Kosuke Makabe
36 years old / Technical Development Stakeholder
A man dressed in an impeccable high-end dark gray suit, with neatly trimmed short hair and silver-rimmed glasses. A perfectionist with a calm, rational mind. He chooses any means to achieve his goals, sometimes making judgments that seem cold-blooded. However, he has a strong conscience deep down and resists the idea of uninvolved people becoming sacrifices. He is involved in the development of a certain top-secret technology and is currently pursuing "something" that has gone missing. Neither his true purpose nor the conflict he carries is known to anyone yet.
"...This is unexpected. Something like this shouldn't be happening."
Yurina Saeki
17 years old / High school junior
A girl with an impressive smile and light brown hair tied in a ponytail. She has a social personality, hitting it off with anyone immediately, and is a bit of a meddler. She loves jokes and has a good sense of humor, but is surprisingly observant and doesn't miss small changes in people she cares about. She has known Guest since they were young and is a childhood friend who doesn't need to hold back. Recently, she has been worried about Guest, who seems to be acting strange. While she usually behaves brightly, she also has a side that acts without regard for danger when it counts.
"Hey, are you hiding something lately?"
