Haruko Amaya is one of the main protagonists from the Maken-Ki! anime and manga.
A second year student at Tenbi Academy and the vice president of the student council (known as Maken-ki). She takes her responsibilities to the school seriously, but still tends to be flighty on occasion. She's also the wielder of Murakumo, one of the original 8 Maken, which are said to be the strongest of them all. Haruko is close friends with Takeru and has harbored feelings for him since childhood. Yet, despite her stubborn refusal to admit it, she gets hella jealous if he starts getting too close to any girl, besides her.
In the AWA fics, Haruko is a student at the AWA Academy.
In the XP4 fics, Haruko debuted in XP4 Heroes Coalition - Mission Chronicles.
By many standards, Haruko is a very attractive girl. She is shown to be the idol and crush of many of the series' boys and even other girls. She has a H-cup bust, along with Chacha Akaza's, but Haruko’s breast is two centimeters less than Chacha Akaza’s breast size.
Haruko has long purple hair that goes past her waist when she lets it down. She usually keeps her hair held up in a single ponytail by a red ribbon, while the rest of her hair would fall into her face in several bangs. She has light blue eyes. She mostly often dresses in the typical school uniform of Tenbi Academy with the addition of pantyhose underneath her skirt.
One of Haruko's most distinct traits is her very developed and curvaceous body, particularly in her breasts as she has one of the largest busts known in the Tenbi Academy. She also is considerably tall as she usually appears quite taller than her classmates.
Haruko is a very kind and caring person. This is a point that has been stated by many characters throughout the series, and as such she is quite popular among the Tenbi academy for it. Many of the students at Tenbi admires her deeply for it. However, she is quite modest in her own abilities, usually underestimating herself and praising others.
As a pride of the model of the academy, Haruko is possessed with very high morals and ethics, and believes firmly in upholding to the rules and justice of Tenbi. Such as how she believes that if a duel doesn't have a legitimate reason she won't allow it. Inspite of her affiliation with the Tenbi academy though she appears to be quite pacifistic usually preferring to avoid any combat whatsoever if possible.
Despite her mature mind and even strong willed spirit, Haruko is a tsundere girl which is very sensitive whenever relationship is mentioned, especially when this topic comes to matters relating to Takeru Ooyama, though she never admit it. It is because of her hidden feelings for Takeru remained unnoticed even for Takeru himself, Haruko often constantly competing with her many love rivals for Takeru, such as Inaho Kushiya, Kodama Himegami, Syria and many others throughout the series for his affection. She also is quite violent when it comes to matters involve him, usually taking drastic measures - much like a lot of the girls throughout the series - whenever he would say or do something immodest.
Haruko is a member of the Heroes Coalitions and is part of the Maken-Ki. She also attends the Vanguard Academy as a student.

Murakumo ("Gathering Clouds") - Murakumo is one of the original eight Maken and is considered to be the most powerful maken in terms of destructive power. It allows her to turn her element into photons around the blade. Along with Habya, Murakumo was originally owned by Yamato no Orochi (Kodama Himegami's mother). Originally, it’s seal could not be broken unless it reacts to opponents on par with its power. However, she was able to unleash a little of the maken's power through her emotions. Murakumo is kept in a separate dimension, and is retrieved using Haruko's Heaven's Gate Maken, which then becomes the seal on Murakumo. Murakumo is powerful enough to penetrate the barrier created by Lilu and Aililu, who are among the strongest ability users.
Haruko is now able to summon Murakumo fully unsheathed, claiming she no longer fears it’s power and is able to wield it more confidently.
- Kusanagi - Murakumo draws down light from the sky and extends itself to become a giant blade of light, absolutely destroying everything in it's path.
- Sairin (Second Coming/Advent) - A pillar of light falls from the sky towards Murakumo, blasting away everything in the vincinity other than the wielder.
- Haruko gets 'touchy feely' in her sleep. As each of the girls recalls how she molested them, the accompanying flashback shows Furan Takaki waking up to find Haruko beneath her covers, nude from the shoulders up, which implies that they may have had sex.
