Mai Natsume is the protagonist of the Remix Heart and the Variable Heart manga as well as the two Remix Heart Gaiden side-stories in Chrono Phantasma Extend and is a playable character in Central Fiction. She was a classmate and friend of Noel Vermillion, Tsubaki Yayoi, Makoto Nanaya and Kajun Faycott during their time at the Military Academy. After leaving the academy she worked at Sector Seven under Kokonoe. Mai is kind, positive, polite and cares for her friends more than anything.

Mai's true name is Mai Hazuki and is the heir of the Hazuki Family, one of the twelve noble families that govern the world. Shortly prior to the events of Remix Heart, the Nameless Grimoire inadvertently fused with her body and transformed Mai from a boy into a girl. She was not able to reverse the transformation and her father sent her away to the Torifune Military Academy under an alias. While Mai initially wanted to return to her previous form, her mind also gradually changed and she eventually came to accept her new form and now considers herself a woman.

Being the vessel of the Nameless Grimoire grants Mai the ability to read the memories or thoughts of people or obtain information about objects by tasting them. Her body later got transformed into The Blank Grimoire, which can utilize whatever power gets inscribed within it. Mai is skilled in martial arts and assassination techniques, though she initially prefered to fight with a sword and a parrying dagger. In Variable Heart she obtained a spear that is a Legacy Weapon called Gallia Sphyra: Outseal and started using that instead.
