Tooru Mutsuki is, biologically, a female. In the early part of the story she prefers to be identified as a male but <strong>later on, she seems to accept herself and her feelings as a girl</strong>.</p>

<p>In <strong>Vol. 1 Chapter 4</strong>, </p>

<p>In <strong>Vol. 1 Chapter 5</strong>, </p>

<blockquote class="spoiler">
  <p>a flashback is shown where people from the CCG Academy Junior school is talking to her and she tells them that <strong>she does not want to be a girl</strong> and that from that moment on, <strong>she wants to be a guy</strong>.  </p>

<p>In <strong>Vol. 7 Chapter 73</strong>, </p>

<blockquote class="spoiler">
  <p>it was revealed that she was constantly abused by her father, and it was hinted that his father may have sexually abused her since he focuses his gaze on Tooru's wet clothes: <a href="https://i.sstatic.net/TWaXU.png" rel="noreferrer"><img src="https://i.sstatic.net/TWaXU.png" alt="enter image description here"></a></p>

<p>As to the last part of OP's post I can easily address that part.</p>

<p>Gender is the internal sexual identity of male/female/neither, while sex is the external bits you got at birth.  So this character is one with some degree of gender dysphoria.</p>

Here's my updated answer, with facts *from the manga itself*, since the manga has long been over and the answers here might still confuse someone, especially since the anime skipped some of the facts I'm about to present.

To start with, the difference between sex and gender is that the former is [biological](https://en.wikipedia.org/wiki/Sex) (male or female) and the [latter](http://en.wikipedia.org/wiki/Gender) 'can refer to either social roles based on the sex of the person ([gender role](https://en.wikipedia.org/wiki/Gender_role)) or personal identification of one's own gender based on an internal awareness ([gender identity](https://en.wikipedia.org/wiki/Gender_identity)).'

**Is Tooru Mutsuki male or female?**
Tooru Mutsuki is, biologically, a female. In the early part of the story she prefers to be identified as a male but **later on, she seems to accept herself and her feelings as a girl**.
