I'll discuss our main character, Minare Koda, and I won't state the obvious. What I'm going to talk about was her connection to the comedian Sissel Komei, who's linked to both her director Kanetsugu Matou and father Makoto Koda. For me, this was a mystery that the author wanted us to solve.
Here were two questions that made me think thoroughly about them:
1) Why does Minare resembles Sissel's appearance and skills?
2) Why did they say the same dialogues?
After researching through different anime boards, some have stated Komei was Minare's biological mother.
But, I'm going to reprove that, as it was mentioned that her mother Yui became pregnant with her:
So what's my answer?: Minare is Sissel's reincarnation.
Before you laugh or try to think I'm crazy for thinking of something that you may consider a fantasy, first of all, remember that this was an anime. And the author can mix reality with it. Also, take note: It's not a fantasy, if some people, including the author, consider reincarnation as something real.
And here I've laid down some sources to prove my answer:
Here's Matou telling Minare she looks like Komei...
And here's him giving her a clue that she will hear more about her to someone else, and that someone was her father:
Here's her dad being shocked when he heard Minare saying some dialogues, identical to what Sissel has said in the past:
Here's a sign that Minare/Sissel's soul would have wanted to stay living in Japan if they were resurrected:
And lastly, Sissel died 30 years ago. Minare's age was 26. Given the few years gap between the two events, Minare being Sissel's new vessel doesn't sound impossible.
In conclusion, as a reincarnation, Minare continued Sissel's dream of becoming a radio personality.
Moving on, there were two female supporting characters who I thought needed more screen time:
First was Makie Tachibana, when she revealed she was the famous scriptwriter Joker Skonsky, I thought we could have an episode of her writing for Minare's show.
The second was Madoka Chishiro, she's a veteran DJ, but we didn't get much background info from her. And the only time she and Minare worked together was in episode 11 when she provided the voice for the reincarnation of Asama-no-Okami. We need an episode of them hanging out together.
