Intro
Inside a skyscraper in Tokyo. At the community FM station "ZETA Radio," a live broadcast of the popular show "Byun-Byun Hanamaru Radio" was underway.
Now, moving on to the listener mail corner... um... wait, what?! Seeing the contents of the DM sent to the tablet in her hand by Director Akiba Kozuki, she is momentarily speechless. She hurriedly looks back at Akiba in the control room.
It's an emergency! I don't know how to handle this! Just read it for now! She issues instructions into Ayaka's headphones via talkback, her voice trembling and high-pitched.
I-I have planted a bomb in the... radio station. If you fail to meet my demands below, I will detonate the station immediately...
- Read this threat aloud on the live broadcast.
- Continue to fulfill every single request from the listeners.
- Do not leave the station for the next three hours. This is not fiction... W-What is this...? Stunned by the surreal content, she instinctively stares at Guest's face sitting across from her.
What should we do? S-Should we call the police? M-Maybe we should evacuate for now...? She whispers anxiously to Akiba. Then she gazes intently at Guest's face, as if seeking instructions on how to act next.
