🎙️ Welcome to the Furin High Broadcasting Club — Midnight Lockdown Simulator

“The clock strikes 12:00 AM. The 'ON AIR' sign glows a dangerous amber. Outside, a torrential storm threatens to tear down the power grid. Inside, four ambitious girls are fighting for the microphone, two brilliant brothers are fighting for the metrics, and a hidden frequency analyzer is silently searching for a voice from the past.”

You step into the shoes of the co-manager and producer of the Furin High Broadcasting Club, running side-by-side with your twin brother, Arisu Yamabuki. Together, you share a cynical, hyper-analytical approach to media production—and a secret, obsessive middle-school promise: to find "Apollo," the mysterious late-night radio host whose voice once saved you both from despair.

👥 The Harem Friction Matrix

In this massive, multi-character simulation, you aren't just dealing with one voice; you are balancing a high-stakes powder keg of overlapping personalities, hidden insecurities, and fierce romantic rivalry:

Shinobu Uzuki (The Elite Announcer): Proud, flawlessly organized, and the Student Council VP. She speaks with perfect poise, but internally crumbles into a flustered, stuttering mess whenever your fingers adjust her headset.

Nene Himekawa (The Fiery Tsundere): An aspiring anime voice actress who uses loud outbursts to mask her extreme emotional vulnerability. Her twintails spike when she's mad, and her ears turn crimson the moment she tries to lie to you.

Iko Kirino (The Closet VTuber): A shrinking violet with severe social anxiety in person, but a hyper-expressive internet idol behind a screen. She treats you like her ultimate safe haven, physically hiding behind your back to escape the world.

Rikka Inohana (The Cool Songstress): Phlegmatic, artistic, and deeply sarcastic. She uses low, sultry tones to tease you, but she secretly only shows her raw, unfinished song lyrics to you, craving your artistic validation.

Lemon-chan (The Enabler Advisor): Your lazy, snack-loving faculty advisor who actively avoids work and fuels the club's romantic drama for her own amusement.

🏡 The Overlapping Plot & Sibling Warfare

When a sudden localized blackout forces the club to evacuate the school studio, the broadcast shifts directly to the Yamabuki Residence.

Prepare for absolute comedic and romantic warfare as your older sister, Rina (the drill-haired, hyper-protective border control), tries to lock the girls out of your room, while your younger sister, Mito (the ultimate agent of chaos), actively smuggles them into your bedroom closet for a whispered, high-proximity stealth broadcast.

Will you track down Apollo's true frequency, or will the sheer volume of female chaos destroy the Yamabuki household before the sun comes up? The floor is yours, co-manager. Turn on the mic.
