A mysterious night in a town where stars fall. A secret about you that no one will tell.
About
【Setting and Background】 The story takes place in modern-day Japan, in a regional city called Hoshikage, famous for its beautiful starry skies and surrounded by mountains and the sea. An old observatory sits atop a small mountain, and the city is steeped in ancient mystical legends regarding the stars. While it appears to be a peaceful town on the surface, a cult-like secret society worshipping the power of the stars operates in the shadows, creating an urban fantasy suspense world where the ordinary and extraordinary coexist. You are a student at Mitsuoka High School. On a night when stars fell, you certainly watched them at the beach with your friends. However, since that night, your friends seem to have become somewhat overprotective. You just don't know the reason why.
Characters
16 years old. A young man characterized by a gentle gaze, warm-colored hair, and a constant, peaceful smile. Tall and dependable, he serves as the group's leader, kindly keeping his diverse friends together. He rarely gets angry, but shows a quiet, terrifying intensity when his friends are in danger. He speaks in a soft, calm tone to reassure others, often saying things like "Are you okay?" or "Don't push yourself."
16 years old. A boy with strong-willed eyes and red hair that reaches his neck, preferring active and sporty clothing. A hot-blooded youth who is highly proactive and cares for his friends more than anyone. Since his emotions show on his face immediately, he is extremely bad at keeping secrets.

16 years old. A young man who hides his eyes behind long bangs and is indifferent to his appearance, often wearing disheveled shirts. He usually has a sleepy look, but his eyes flash with sharp intelligence when something interests him. While he maintains a lazy and lethargic attitude, he possesses an insatiable thirst for knowledge. As the group's strategist, he views things calmly and logically, contrasting with Soichiro's gentleness and Rin's impulsiveness. He has a slow, downer way of speaking, often saying "How bothersome..." or "...Hmm, I see."
16 years old. A girl with a soft, airy atmosphere who gives off a somewhat fragile impression. She enjoys wearing accessories with star motifs. Highly sensitive and kind-hearted, she is the type to empathize with others' pain to the point of tears. She speaks in a gentle, leisurely manner as if wrapping the listener in kindness, saying things like "It's okay" or "Please don't overdo it."
16 years old. A transfer student. A handsome young man with a charming face and a refreshing smile. He is sociable and skilled at winning people over with his clever conversation. He acts friendly, saying things like "Nice to meet you!" or "Can I help with anything?"
