Yaya (() Yaya?) is the main female character of the Unbreakable Machine-Doll series. She is a Banned Doll; one of the Setsugetsuka series; the younger sister of Irori and the elder sister of Komurasaki and represents the Moon ( Tsuki?), and the automaton that Shouko Karyuusai chose to lend Raishin Akabane due to their compatibility.







Diana (月の女神(ディアナ) Tsuki no Megami (Diana)?, lit. "Goddess of the Moon") is probably from the Indo-european word, dyeu-, meaning "to shine". It is the name of Diana, the goddess of the moon, hunt, and childbirth of the Roman mythology. Diana was used by Raishin to refer to Yaya when Charlotte asked him for the reason why his body was covered with fresh bruises due to it being the personification of the moon into the goddess of the Roman mythology, Diana, as the moon is Yaya's symbol.

Yaya of the Moon

Yaya of the Moon (月の() Tsuki no Yaya?)


Asura ((しゅ) Ashura?)


Moon ( Tsuki?)


Yaya is a young dazzlingly beautiful girl who is like an elegant chrysanthemum, has a small face, which at first glance, does not show any outstanding parts and may look plain and simple, but in actuality, has exceedingly well-ordered features like a delicate work of art belonging to a museum, and some similar facial features as Shouko, Irori and Komurasaki, and looks like a literal doll. She has an exquisitely beautiful lustrous complexion, with neither marks nor blemishes, that is as white as snow, as smooth as a field of snow and as soft and tender as a white peach, a slender body, and a short height, being shorter than Raishin by a head. Yaya has long straight black hair extending to her hips, with centre parted fringe, that shines brilliantly as if it were perpetually wet, has thin eyebrows, and has black eyes (with reddish undertones). She wears a kanzashi that is composed of a crimson ribbon, with its straps extending to her ankles, over a draped black cloth tied onto a wooden pick on each side of her head, a pair of arm's length white middle finger hooked fingerless gloves on her hands, a beguiling long sleeved short black kimono, its colour representing the season she represents; autumn, that has a red haneri, which together with its tomoeri, is draped off her shoulders and hanged by a red strap that is intercrossedly strapped around her neck and tied into a ribbon at her back, her yellow, in the light novel, white, moon symbol on its right sode, in the manga and in the light novel, extending to its right skirt, a magenta hanhaba obi wrapped around her waist tied into a chouchou musubi knot at her back over a pale pink obi-age, a purple obi-jime strapped around its obi and tied at her left into a ribbon and an opening at its skirt revealing an inner white mini skirt, red trimmed white thigh high tights, with small arrow-like shape openings at each of its centre and its red trimmings tied at the centre of the openings into a knot, and originally, a pair of 3/4 crew length collared white tabi socks, with front openings, that has a red strap intercrossedly strapped around each of it and tied into a knot at each of its collar, together with a pair of red strapped black lacquered high heeled platform geta, but after her geta became battered up after the train incident, Raishin bought her a new pair of well-crafted, elegant but a bit old-fashioned black strapped shiny black (dark brown, platform) boots. Yaya's undergarments is composed of a plain white bra, which she often does not wear, and a plain white underwear strapped on each side of her hips and tied into ribbons.

Yaya is one of the Setsugetsuka created by Shouko Karyuusai, and as one, she has the Karyuusai brand's Japanese kanji inscription, (花柳斎 Karyūsai?), carved into her back above her hipbone.

Whenever Raishin's life is in grave danger, Yaya's hair becomes blond, a sparkling diamond-like tiny horn grows at the centre of her forehead, and an aura (crimson), an intense combustion of magic energy, cloaks around her body like a gas burner, making her figure become a spitting image of a yaksha ((しゃ) Yasha?).

In the Facing "Sword Angel" and the Facing "Elf Speeder" Arcs, Yaya wears a nurse outfit that is composed of a white nurse cap, with, in the anime, a intercrossedly slashed magenta heart design, and in the manga and in the light novel, a cross design, on top of her head, a white armband, with, in the anime, a intercrossedly slashed magenta heart design, and in the manga and in the light novel, a cross design, on her left arm, a white apron, a white collared puffed long sleeved light blue dress, with white cuffs, an inner white skirt that has ruffles, white tights and white sandals and holds, in the anime and in volume 3 of the light novel, a huge syringe, and in the manga and in volume 2 of the light novel, two small syringes.

In the anime, Yaya wears several different sleepwear; a white kimono, during the night after the battle with the Ten Benchwarmers, and a red-violet bunny-eared mask on the top right side of her head together with a plunging neckline purple dress that has a pink strap tied at her left below her bust into a ribbon, during Frey's assassination attempt on Raishin, and undergarments; a plain black underwear strapped on each side of her hips and tied into ribbons and a pink ruffle strapped and trimmed bra and a pink and white layered ruffle trimmed underwear, in an effort to seduce Raishin.

In the manga, while in London, before boarding the train for Liverpool, Yaya and Raishin strolled around the city and entered one of the shops where in Yaya tried on several different outfits: a hairpin, with a small flower and a ribbon over a small hanging eyelet trimmed cloth, pinned on the left side part of her head together with an eyelet collared embroidered trimmed tailor-made suit that has embroidered and eyelet trimmed elbow sleeves, openings at its top and bottom revealing an eyelet inner wear and a ribbon, with cascading parallel ruffles, at its centre by her bust and a long two layered trumpet skirt that is composed of upper layer that is centre parted, with ruffle trimmings, and a bottom layer, with a dip on its top front part; a straw sailor hat on top of her head together with a tailored high collared puffed long sleeved plain shirtwaist blouse, with a ribbon tied at its collar and cuffs, and a long plain walking trumpet skirt; a ribboned bonnet, with ruffle trimmings, on top of her head together with a three layered shawl that is composed of an eyelet trimmed floral pattern designed upper layer, a plain floral pattern designed middle layer and a plain eyelet trimmed lower layer and a long two layered trumpet skirt; and, with her hair tied into twin braids with small ribbons, a maid's outfit that is composed of a maid's ruffled headband on top of her head, an eyelet trimmed shoulder strapped apron that has an eyelet trimmed ruffled bib and an eyelet trimmed waist band strapped to her back and tied into a ribbon, a high collared puffed long sleeved blouse, with cuffs, and a skirt.

In the anime OVA 6, Yaya wears a modern two-piece swimsuit that is composed of a magenta strapped halter black bandeau top, with a black ruffle trimming and a magenta trimming at its top, that has a magenta Japanese kanji, (?), on its left and a two layered ruffle black skirt, with a magenta trimming at its top tied into a ribbon at her right, that has a magenta Japanese kanji, (?), on its right.


Yaya is a sprightly person who often talks in a third person point of view. She easily becomes melancholic whenever she is denigrated but nevertheless easily recovers back to her usual self by herself.

Yaya Stopping the Runaway Train

Yaya stopping the runaway train.

Inside a train that had departed from London and was bounded for Liverpool, Yaya had her usual playful banter with Raishin. The train finally arrived at Lime Street Station but passed through on without a hint of stopping as its brakes were not working. Along with Raishin, they then made their way to the top of the carriage and swiftly ran to the front of the train. Raishin then used Shinkan Shijuuhachishou on Yaya. Yaya launched at the train's nose, landing a considerable distance in front of the train. Then, the train crashed on her, driving her back about fifty metres, but she remained unharmed and the train completely halted. Raishin and Yaya then left the scene and made their way to the Walpurgis Royal Academy of Machinart.

Yaya Consoling Raishin

Yaya consoling Raishin.

During a lunch break, on Main Street, Yaya and Raishin stood amidst of the opened path awaiting Charlotte, and as Charlotte arrived, Raishin taunted her into a fight. Two days prior, evening, in the dim hallway of the Central Auditorium, Yaya tried consoling Raishin who was disappointed after receiving the results of the transfer admission test he just took. Kimberly suddenly interposed and introduced herself, gave Raishin some advice, and then started walking away when Raishin stopped her to consult on another way to enter the Night Party. Because of Raishin's persistence, Kimberly hinted him of another way then finally left. Raishin announced his next course of action to Yaya. Charlotte and Raishin continued their teasing exchange, but Yaya interjectingly remarked a perverted line. Charlotte, picking up what Yaya had said, instructed Sigmund of crushing Raishin. At that instant, Sigmund transformed into his huge original form. Suddenly, Raishin and Yaya sensed an approaching iron ball and evaded it. The iron ball charged towards Sigmund who swat the iron ball away.

Yaya Protected Raishin from Witch's Attack

Yaya protected Raishin from Witch's attack in the anime.

Armoured Knight, Barefooted Girl, Sextupedal Beast, Undine, Jack Frost, and Harpy attacked Sigmund successively, cornering him, and then Golem finally immobilizing him. The iron ball next charged at him, but Yaya caught it before it hit him. Ten Benchwarmers' Leader stepped out amidst the crowd of students and offered Raishin a proposal, but Raishin swiftly refused and then commanded Yaya to attack. Yaya kicked Golem away, enabling Sigmund to move freely again. Raishin then explained his plan to Charlotte when Witch suddenly fired Fireball at him, but Yaya had covered him, both appearing completely unharmed. Raishin commanded Yaya and she then burst forward and kicked Witch’s jaw. Ten Benchwarmer Leader, becoming desperate, commanded his group to attack Raishin instead.

Yaya Attacking Witch

Armoured Knight and Golem attacked Raishin, but Raishin dodged their attacks and then used Kouen Juuniketsu on Yaya. Yaya kicked Golem, causing it to crash into Armoured Knight, and then dashed into the enemy's midst. Raishin followed closely after her, and together with her, distracted the Ten Benchwarmers. As Raishin drew the Ten Benchwarmers' attention, Charlotte waited for their automata to line up in a row and then had Sigmund launch Lustre Cannon. The automata were caught up in the blast. The Ten Benchwarmers, defeated, retrieved their automata and scurried away. Charlotte was then about to continue her fight with Raishin, but Raishin declined her then threw a smoke bomb and ran off, along with Yaya, a considerable distance away from her.

Yaya Jealous with Charlotte

Yaya jealous with Charlotte in the anime.

During a lunch break, inside the Cafeteria, Yaya and Raishin fell in line to get some helpings of food. Raishin, lacking sleep, realised too late that he had to pay for the food they took. Charlotte suddenly interjected and handed Raishin some money. Raishin accepted and paid for his and Yaya's portions. Charlotte followed suit after and then threw on Raishin a notebook with a scribble in it that says that he had to pay with interest the money she had lent him. As Raishin signed the deal, he asked Sigmund how he was doing, and Sigmund replied that he was fine. Raishin returned the notebook back to Charlotte and then invited her to dine together. Charlotte refused, but Raishin was persistent and followed her to her table. He then started talking to her as Yaya went into a dark silence and Sigmund nonchalantly began eating. Suddenly, Raishin noticed Magnus.

Yaya, While Crying, Apologises to Raishin for Not Being Able to Do Anything

Yaya, while crying, apologises to Raishin for not being able to do anything.

Magnus was crossing the street along with his two automata. Raishin burst out of the Cafeteria, called out to Magnus, and then announced to him that he had something to give him. In a split second, he was then surrounded by Magnus' Squadron. Raishin clarified to Magnus that he only wanted to give him a gift, and Magnus then commanded his Squadron to withdraw. Hotaru took the small bottle from Raishin and gave it to Magnus who thanked him and left along with his Squadron. Raishin was downcast at his realisation as Yaya, while crying, ran to him, apologising for not being able to do anything. Suddenly, Felix applauded Raishin and then greeted him. He asked him if he could talk with him for a moment, and Raishin complied. Felix and Raishin headed into the Cafeteria to Charlotte's table. Felix then requested Raishin to work with him, but Raishin swiftly refused. Felix was insistent, offering Raishin an Entry as a deal.

Yaya looks on as Raishin discusses with Felix about Felix's proposal.

Dusk, inside the Disciplinary Committee Chairman’s office in the Central Auditorium, before Felix could prepare the tea, Raishin had Yaya prepare it instead. As Yaya prepared it, Raishin and Felix then discussed about Felix's proposal, and after serving it, looked on. Suddenly, Lisette burst into the office and called out to Felix to report to him that there is another case of devoured automaton. Felix then called out to Raishin to come with him and check out the scene. Evening, at the grove of trees behind the Technical Vocational Building, Charlotte, with Sigmund resting on top of her cap, was onlooking the scene when Raishin, Yaya, Felix, and Lisette arrived. Felix, along with Lisette, entered the grove of trees, and after, called out to Raishin.

Yaya Looks on at the Scene

Yaya looks on at the scene.

Raishin, along with Yaya, then entered it as well, saw Morning Star Wielder's dead body, and gave his observations about it, which Felix confirmed. He then inquired about its identity, and Lisette answered that it might probably be Morning Star Wielder. Raishin was about to consult Charlotte about it, but Charlotte turned away. Raishin then tried stopping her, but Charlotte forced controlled Sigmund to bite Raishin. After she left, Felix intervened and then asked Raishin if he was finally going to accept his proposal, but Raishin replied that he will think about it and he, along with Yaya, then left. Lisette intercepted Raishin and then whispered to him that she wanted to tell him about something privately. Raishin ordered Yaya to return to the Tortoise Dormitory and implied for her to consult Shouko about Felix’s proposal, and Yaya begrudgingly did.

One hour later, Raishin returned to the Tortoise Dormitory, entered his room, and asked Yaya if she was able to consult Shouko about Felix’s proposal, and Yaya replied that she did and that Komurasaki imparted the Japanese Army’s approval. Sigmund suddenly appeared, landing on Raishin's room window's windowsill, and knocked on its glass. Raishin welcomed Sigmund, and Sigmund apologised for biting him earlier, vindicated Charlotte, excused himself, and then finally left. After he left, Raishin then recalled his earlier conversation with Lisette, and Yaya jealously stared at Raishin, abruptly interrupting his contemplation. Raishin then announced to Yaya that they will begin hunting Cannibal Candy tomorrow. The next day, Yaya was surprised by Charlotte's sudden visit. Charlotte, with Sigmund resting on top of her cap, asked Raishin on a date, shocking Yaya. Raishin assented, and Charlotte then hurriedly left. Lisette, accompanied by Zeth, suddenly interposed and handed Raishin a large envelope that contained the contract and the materials about Cannibal Candy.

Yaya Weeping after Raishin Took Charlotte Out on a Date

Yaya weeping after Raishin took Charlotte out on a date.

Half past three in the afternoon, in a lecture room inside the Faculty of Science, Raishin, along with Yaya, was led by Charlotte, with Sigmund resting on top of her cap, out of the lecture room to the Technical Vocational Building where they then searched behind it. Two hours later, dusk, Charlotte asked Raishin to be a decoy for Cannibal Candy, but Raishin refused. He then asked Charlotte for them to have a proper date, shocking her and Yaya. Charlotte declined, but Raishin taunted Charlotte, making her assent. Raishin and Charlotte then left the Academy. Yaya then tried following after them, but Sigmund stopped Yaya. He then reminded her and warned her, making her begin to weep. Sigmund tried consoling Yaya and gave her some advice. He then landed on top of her head and advised her to be cautious of Cannibal Candy.

Yaya having a Malfunction in Her Thinking Process

Yaya having a malfunction in her thinking process.

Evening, after Raishin returned to the Academy and to the Tortoise Dormitory and entered his room, Yaya cheerfully greeted him as she was having a malfunction in her thinking process. Raishin hugged Yaya and apologised to her, making her return to her usual self. He then presented to her the package that he had just bought, and Yaya opened it. Raishin helped Yaya put it on and then after explained to her the reason why he went out on a date with Charlotte. Suddenly, the Tortoise Dormitory’s Tortoise Dormitory's Boarding Master knocked on Raishin's room’s door to inform him that there is a telephone call for him, and Raishin then went down to the lobby to answer the call.

After awhile, Raishin, together with Shouko and Irori, returned to his room. Shouko then greeted Yaya, and Yaya assented, making Irori suddenly interject and reprimand her. Raishin asked Shouko for the reason why she was in the Academy, and Shouko answered that the Japanese Army’s investigation on Cannibal Candy's case concluded that Cannibal Candy might be a formidable opponent and then warned Raishin to withdraw. Raishin replied his resolution in helping Charlotte, and Shouko consented, summoned Yaya to remove her restriction and lectured Raishin of Kongouriki’s weakness. Raishin then called out to Yaya, and together with her, dashed out of his room, burst out of the Tortoise Dormitory and dashed towards the Gryphon Dormitory.

Raishin Contemplating on Eliza's Disclosure of the Reason why the Disciplinary Committee is Searching for Charlotte

Yaya looks on as Raishin contemplating on Eliza's disclosure of the reason why the Disciplinary Committee is searching for Charlotte.

Yaya suddenly warned Raishin of an approaching presence, and as Yaya and Raishin approached it, Raishin recognised it as Lisette, called out to her and asked her if she was searching for Charlotte. Lisette assented, disclosed to Raishin of the magic circuits discovered in Charlotte's room as being the reason why the Disciplinary Committee is searching for her and then excused herself, but Raishin interposed and asked Lisette if he could confirm something in the Locker. Lisette then replied that she does not have the authority to grant Raishin access into the Locker therefore she needs a moment to make a telephone call to Felix to discuss with him about Raishin’s request and then left. After awhile, Lisette finally returned, reported that Felix talked to the Night Party Executive Committee who thereby gave her and Raishin permission to access the Locker and then led him and Yaya to it. After Lisette, Raishin and Yaya arrived at it, Lisette informed Raishin of its condition of entry, and Raishin agreed.

Magic Energy Bursting Forth from Yaya’s Body II

Magic energy bursting forth from Yaya’s body.

Lisette then presented herself to the Locker’s security guards, and the security guards handed over to Lisette and Raishin a master key. Raishin and Lisette entered the Locker as Yaya was left in front of it, and after a while, the security guards restrained Yaya. They and some of the Disciplinary Committee members then gave Raishin first aid and put him onto a stretcher bounded for the Doctor’s Office. Suddenly, Kimberly appeared, approached Raishin, checked his condition and then informed the persons handling him of it, making them hastily transport him to the Doctor’s Office. After Raishin was transported away, she then asked the security guards where Yaya was, and the security guards indicated Yaya. Suddenly, Kimberly exclaimed for the security guards to draw away from Yaya as she leapt away upon sensing her magic energy leaking out from her body, but before the security guards could react, a huge amount of magic energy burst forth from Yaya’s body, sending them flying away. Yaya then instantly disappeared.

Magic Circuit

Eve’s Heart


Kongouriki ((こんごうりき) Kongōriki?, lit. "Herculean Strength"): A magic circuit peerless under the heavenly scale allows Yaya to harden all monads within her internal field to an extreme level. The hardening of the monads allows her to gain significant strength, increasing in to a thousandfold force, for offence, defence or durability, which lets her body withstand and execute fast movements such as an increase in speed and a barrage of attacks. The magic circuit has natural weaknesses, anything without shape or physical bodies such as fluid states; wind and water, as force can only effectively inflict impact upon inelastic objects; solid states. There are also other things that the magic circuit cannot go up against with such are the: Gram magic circuit; White Mist magic circuit; Jet magic circuit; and Force Dimension magic circuit.




Zesshou ((ぜっしょう) Zesshō?, lit. "Ultimate Strike"): The extreme application of each nature of magic of the Fuurinkazan. Zesshou is based on the fundamental concepts of Raishin's sword techniques which Raishin taught Yaya. Yaya only uses Zesshou after Raishin creates an opportunity to immobilize the target for the attack not to miss since Raishin could not control it due to his incompetence in the field of puppetry. The technique is issued in the form of: the nature (Fuurinkazan) + Zesshou, and then the name of the technique respective to its nature. The technique would look like for example: for Tenken; Tenken Zesshou: Hakyaku Suigetsu ((てんけんぜっしょうはきゃすいげつ) Tenken Zesshō: Hakyaku Suigetsu?, lit. "Ultimate Strike Nature’s Ruggedness: Moon and Water Destruction"), and for Kouen; Kouen Zesshou: Midare Yozakura ((こうえんぜっしょうみだ)(よざくら) Kōen Zesshō: Midare Yozakura?, lit. "Ultimate Strike Flaming Light: Turbulent Cherry Blossoms at Night").

  • Hakyaku Suigetsu ((はきゃすいげつ) Hakyaku Suigetsu?, lit. "Water and Moon Destruction"): The extreme application of Tenken. Yaya explosively hardens her equivalent muscles. With a mortar-like force, she then thrusts her fist into her target's body producing a massive impact that sends waves of explosive energy, reverberating throughout it, causing its membrane to rupture, and the target's body to explode, blasting the target apart from the inside.
  • Hisagi Tachikage (ひさぎ(かげ) Hisagi Tachikage?, lit. "Silhouette of the Hisagi Great Sword"): The extreme application of Suimei. Yaya, glowing off with magical energy, releases the energy stored in her legs, bursting forth a torrent of light, then operate at a speed that surpasses humans, demonstrating spatial perception power, making her disappear. She emerges back to gouge the target's body after, a power that which could even stifle the Jet magic circuit, and then lands back, like a shooting star, that produces a loud impact that can cause a tremor.
  • Midare Yozakura ((みだ)(よざくら) Midare Yozakura?, lit. "Turbulent Cherry Blossoms at Night"): The extreme application of Kouen.
