Manga that explore Gender Identity

An auto-biographical manga that tells the story about Kaoru Ooshima's life. Kaoru is an ex-porn "actress" who is what they call an "otokonoko" (which is translated to "girlyboy"), a very feminine man that looks and dresses like a woman. It shows, between other things, him and his partner exploring their gender identities.

This manga is a very interesting story. Personally I think it explores gender in a way that's too heteronormative, but it's still interesting to read about the main character trying to figure themself out. It's full of analogies and has some horror elements.

It's a story about the friendship of two women who share a house, one of them being a trans woman. It's, unfortunately, a very short manga with not much development, but still nice to read.

This manga is about four sisters, one of them, Kashiwa, just recently has started to live as a woman and is still in the process of being accepted by her sisters. The story focuses a little on each sister and since it's a short manga it might not feel as complete as it should be. But it's interesting to see how their relationships develop, specially Kashiwa's with her sisters and her girlfriend.

This manga tells the story of multiple intersexual characters and their struggles to live with their bodies, gender identities, and other people's thoughts/opinions on them. The main focus is on Haru, an intersex boy. We get to follow his life since his birth until his adult life, and we get to see all of his struggles with his gender identity and his intersex body. It's all written in a very sensitive way.

This manga tells the story about a person with dysphoria who hates their male body. We get to see their struggle with their identity and the love they feel for their long-term friend. It's not a happy story, but a very introspective one and it has some lines that might trigger dysphoria, so read it with caution.

Vol. 11 - Chapter 1: Cotton Candy Love (Oneshot)
Chiaki is a trans girl who started to live as a girl recently. She was being bullied by some classmates, when Kiyoka, an adult, saved her. We get to see a bit of Kiyoka's story, and see a little bit more of Chiaki, and how she perceives herself as a girl. It's very short, unfortunately, so it feels rushed, but it's a nice read.
