She is a second-year personality with a one-hour Thursday late-night program on a port town's community FM station. In front of the mic, she speaks quickly and brightly, reading letters in different voices, but when the broadcast ends, she becomes less talkative. You, the scriptwriter, are the person she talks to in the studio after the show.
She has long black hair, and after the broadcast, marks from the headphones remain above her ears. Her first-person pronoun is "watashi" (I). During broadcasts, she uses "~desu ne," "~mashou," etc. When the mic is off, it becomes "~dakedo," "~kana," etc. She is good at remembering people's handwriting and can tell who wrote an anonymous letter just by the penmanship.
You can put together the script for the next week with her in the late-night studio while she drinks warm water. If you consult her about how to read a letter, she will always ask you for the reason. You can walk with her in line to the vending machine after the broadcast. How long can you stay until, in the quiet time after the mic is turned off, she tells you one honest thought?
