Childhood best friends Nao Mamiya and Kyousuke Miyoshi have always competed against each other, whether in academics and sports or trivial day-to-day things. Despite Nao winning every time, Kyousuke refuses to give up, hoping to defeat him in the future.

One day, however, at the age of 17, Nao is struck by a sudden illness and is hospitalized for several weeks, only to return as an "emerged" female. Much to the dismay of Kyousuke who is afraid of women, Nao easily accepts the situation and is ready to continue living life as a girl.

In a world where a gender shifting mechanism maintains a fixed male-to-female ratio, Kanojo ni Naru Hi is the tale of Nao as a boy who has switched genders, adapting to the change in his circumstances.

[ Contains Spoilers ] ( First Review For Manga Without Adaptation And Boy x Girl )

When I was thinking about what I should write in this review for this manga. I thought about the manga's story about how the boy became a girl and imaged myself in that scenario as the MC. Imagining my friend become a girl.. It's unimaginable in fact but it does sound quite humorous. Fun fact, just right after I finished pondering and I read the next page ( final chapter - around where their daughter grew ). The name of my "childhood" friend pops up as the name of read more

Story: 6/10

The premise of this manga is almost irresistible for someone like me, who is part of the LGBT community. In a world where the male-female ratio is equal, when there is an imbalance, a person will ‘emerge’. That is to say, a person will change from one gender to the other, on a chromosomal level. I couldn’t wait to read this when I heard about it. I wanted to see the impact that such a change would have on psyche, but it barely delved into that aspect of the story. If you are expecting a deeply meaningful, psychological manga with read more

A brief summary of my thoughts is that, Kanojo ni Naru Hi isn't bad but it's not great either. Read it if you want, just don't take it too seriously.

With that out of the way, Kanojo ni Naru Hi is a manga that, more so then any other I've read, will vary depending on what you want this manga to be. Don't get what I mean, that's fine I'll try to elaborate.

The first thing you'll notice when you approach this manga is the premise, a guy spontaneously transforms into a girl and it's out of his, or her, control. After that it follows read more

Usually, when it comes to gender bender stories they're preoccupied with turning back into the gender they started with, however, this felt surprisingly refreshing in how quickly the change was accepted (in a way the world they live in helped) and because of that, this felt like a trans story.

In the beginning, you can tell that this was supposed to be very short, like a few chapters at most, so there are some very small inconsistencies to the story when new elements are added, but overall it is really well done and the characters continue to be layered throughout the short 20 chapter run.

The characters read more
