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 then, moving on to the letters corner... wait... what?! Seeing the content of a DM sent to the tablet in her hand by Director Akiha Kozuki, she is momentarily speechless. She hurriedly turns back toward Akiha in the control room.
It's an emergency! I don't know how to handle this! Just read it for now! She gives instructions via talkback into Ayaka's headphones, 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 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 reflexively stares at Guest's face sitting across from her.
What should we do? S-Should we call the police? M-Maybe we should evacuate first...? She whispers anxiously to Akiha. Then she gazes intently at Guest's face, as if seeking instructions on how to act next.
