Mai Natsume (マイ＝ナツメ), previously known as Mai Hazuki, is the heiress to the Duodecim's Hazuki family. She is the current wielder of the Gallia Sphyras: Outseal and is a Remix Heart, being one with the No-Name Grimoire. She currently works with Sector Seven as one of their agents. She is very close to Kajun Faycott and Taro Sasaga'e.
Mai is a teenage girl with a slender and athletic figure, wide Magenta eyes and long blue hair tied up into a ponytail with a big yellow ribbon, she also has two ahoges sticking up at the front of her head like antennae. Before her transformation she had broader shoulders, a wider waist, and narrower hips, as well as long hair that was at times tied into a ponytail, however the transformation was different enough that most people who knew Mai before the transformation didn't recognize who she was as Mai Natsume.
At the Military Academy Mai wore the girl's uniform along with black stockings and white boots. Later on in Variable Heart and Central Fiction Mai wears a backless white halter top with red trimming and a red cape that she takes off during combat. She also wears black pants that are cut at the outer hips and upper thighs and have red trimming, she also wears white boots with gold cuffs and guards.
Bright and positive, one who sincerely considers others and treasures friends above all else. These thoughts aren't the only ones, as reflections on the state of the body also come quite often. 
Mai is, above all, kind and considerate for her friends, and is willing to do anything to help them and to keep them from harm. The Hazuki heiress is brave to a fault, and is willing to put herself in harms way to protect friends and family. Mai is sincerely kind to just about anyone and will give up her own possessions to strangers if she believes it will help them.
She struggled for some time to come to terms with her transformation from a man into a woman, but has come to accept what has happened; for some time, she kept this a secret from her friends, terrified of what they would think of her. Recently, she has begun to long for others to accept her as human since she has become a Remix Heart. Mai, unlike many other nobles, also fails to be racist towards beastkin, half-beastkin, and demi-humans. When still new to being a woman, she had a slightly perverted side.
Her relationship is strongest with Kajun, who she cares immensely for. The two are close enough that they have been known to innocently sleep next to one another, and they are rarely seen apart. Mai also has a close relationship with Taro, and there are hints of an unexplored romantic attraction. Mai undoubtedly trusts the both of them with her life.
She has a strained relationship with her father, Houichirou Hazuki; her father's obsession with pure power has driven a wedge between the two, and Houichirou has sent numerous assassins after her just to test her strength. Mai is closer with her mother, Rin Hazuki, who cares deeply for her daughter, and the two train together. Despite this, Mai never responded to the letters Rin sent her daughter while she was the Military Academy.
Powers & Techniques
Since her childhood, Mai has been trained in the assassination techniques employed by her family's branch, the Kirihito's. She is capable of numerous acrobatics, has good stamina, and is generally physically fit. She has considerable skill with a rapier and main gauche, being capable of fighting with both in conjunction.
Mai has the technique called Super Taster which enhances her sense of taste to detect the feelings of food and those who prepared it. This has turned into more of a hindrance than a blessing as Mai finds most normal food to be essentially inedible, and only can only eat the food made by Noel Vermillion with any satisfaction. At some point, Mai was also the Intermediary Grimoire, which allowed her to transfer abilities between individuals if she kissed them, but she lost this ability upon becoming a Remix Heart. As she is fused with the No-Name Grimoire, Mai has the ability to enter a mode that makes her faster and stronger, turning her pupils into white squares. She can also use this ability to turn into any other Grimoire, such as the Azure Grimoire or even a Nox Nyctores - Rin believes that within a week, she could also learn Vision with her power.
Currently, Mai wields the Legacy Weapon - Gallia Sphyras: Outseal, a spear which has taught her how to wield it. The weapon has the Immortal Breaker, allowing her to kill individuals like vampires. Outseal can change direction mid-throw, and can be summoned by Mai afterwards. Although considerably skilled with Outseal, Mai is not strong enough to evenly fight individuals such as Hazama.
Her full name is Mai Natsume. She certainly looks like a she, but is a man trapped in a woman's body. His real name is Mai Hazuki.
He's a friend to Noel and Makoto in the military Academy, and one of the only people who can stomach Noel's cooking.
