Mahiru Hīragi

Mahiru Hīragi 「柊 真昼, Hīragi Mahiru」is the love interest and the demon weapon of Guren Ichinose. She was also the next successor to the main house until she turned into a demon weapon called Mahiru-no-yo.

Appearance
Mahiru has long ashen hair with a front fringe. She has brown eyes and is quite short, like her younger sister, Shinoa Hīragi. Unlike Shinoa, she has a well-developed figure.

Personality
She has no qualms about betraying family, according to Shinoa. The fact that she became a possession-type demon suggests she is particularly violent.

History
Mahiru along with her younger sister Shinoa, were conceived through artificial insemination using the seed of Tenri Hīragi in a demon-possessed woman.

Later on, her research on demons eventually turned her into one until Guren killed her. She became the demon within his Cursed Gear and part of the Black Demon Series.

Manga
Although she is present as Lieutenant Colonel Guren Ichinose's weapon from the moment Guren appears in the manga, readers first see her human appearance at the beginning of chapter 17.

Post-Shinjuku Arc
In the following chapter, Guren reveals her form to Sergeant Shinoa Hiragi, who is concerned Mahiru may be controlling Guren behind the scenes. She is Mahiru's sister, and they share both the same mother and father.

Nagoya Arc
In chapter 23, she appears and whispers to Guren in order to make sure he follows her rather than Lieutenant General Kureto Hiragi.
