This is not your everyday manga. It strictly deals with cases of intersexuality. I.S. stands for Inter Sexuality.

This manga deals with very serious issues with intersexuality people. The pain they go through, the troubles they confront, and ultimately their inability to reproduce and even find a partner who will accept them as they are - It's all there in a form of manga.

The series is consisted with cases, each deals with different people though some cases are much longer and more dramatic than others.

Don't be discriminatory towards the strange title of this manga. Don't worry, this is not yaoi, nor yuri, nor ecchi or hentai. In fact, this is one of the most touching and most mature shoujo/josei manga I have read. Of course, the main characters are intersexuals.

Story: the first bolume is composed of short storis while the rest is Haru's story. Although you will not encounter very deep plot (remember, this is a shoujo manga), the different chain of events that are changing the characters' life and personalities are very original and refreshing. The narration is very interesting as it swtiches POV back and forth read more

Warning: This review is a bit long and a bit long winded at times.

I.S. initially drew me in because hey-- how many manga are out there that are about intersexed individuals? I'm a fan of Hourou Musuko among a few other manga that deal with gender identity and sexual orientation so upon seeing this, I got excited and immediately went on a hunt for it.
If this were a review of the first story, Case 1, I would score it like this:

It's short, but very sweet. I easily was able to feel for the protagonist Hiromi and though the translations were rough, I was nearly read more

Intersexuality is one of the mangas that really made me cry, regardless of which chapter I'm reading. It is truly emotional and it shows how people who are different have to survive in a society that forces you to conform. I love the storyline which is very different from other mangas and the impact that the manga gives to the readers is just amazing. It also gives the readers more awareness of intersex people, who are neglected by society and never get the chance to voice how they feel.

I.S. is one of the manga out there that I really loved. Not, because there's romance and mushy feelings that drown your sorrows and make you think 'Oh, perhaps I have a chance and one day my prince will come'. That's utter bullshit, as far as I'm concerned. It does, however, have warm feelings packed within it. Soft feelings, and sorrow. The pain of being different is shown very clearly in this manga, in many different ways. Being 'different' isn't something that a lot of people openly want, most people just want to fit in and be 'normal'. This shows in this manga, where being read more
