Hello,
I'm looking for mangas with first person narrators where the main character is kind of cold, aloof, weird, a bit twisted maybe and have great observation skills. I like the kind of mangas where you really follow the main character thinking. It can be something dark or something lighter, it can be a psycological manga, a romance one, a sports one... I'm ok with everything including yuri or yaoi.
For exemple I've read and liked : Warau Kanoko-sama, Onani Master Kurosawa, Ore ga Doutei o Sutetara Shinu Ken ni Tsuite

I also like mangas where the narrator and the main caracters aren't the same person as long as the main character kind of fit my earlier description, the narrator can be someone more normal who's kind of attracted, fascinated by the mc. Or it can be something without a really defined narrator. Something like akagi, J no Subete, Life, Love or even Billionaire Girl

Any suggestions ?

Perfect for u: Yahari Ore no Seishun Rabukome wa Machigatte Iru. - Mougenroku
