First episodes are really crucial in any anime specially short ones like talentless nana. I don't want to spoil anything for anyone but the first episode will exceed your expectations and it just keeps getting better.
The inner monologues of the two main leads is most likely the best part of the anime. I also like how everyone confronts each other. And the mystery is so simple yet so complex. The only thing that kind of disappointed me was the background characters. We could have seen more of them but considering the show covers a long story in a fast pace that's kind of understandable.
Nana is by far the best character in the series followed by kyoya. Her intelligence probably exceeds other overrated characters' like... I'll leave that up for you.
This show is a hidden gem. Had an ending which was not really an ending BUT the rest of the show is a 10/10. Who knows why it's got such a low rating, it deserves more recognition. I feel like if this anime was animated by a famous studio it would've got the recognition it deserves.
Sorry I couldn't tell you about the anime as it's difficult to talk about it without spoiling since the twist starts from the first episode. Trust your gut and watch it like I did, you won't regret it.
