Saki Sukinasaki (須木奈佐木 咲, Sukinasaki Saki) is an idol in league with Jyuujika Hachiningatake and Zomeki Furousan. Together, they form the group Kiyoterae (キヲテラエ, Kioterae). A former student of Suisou Academy, Sukinasaki is the secondary protagonist and chief antagonist of the Medaka Box sub-series, Good Loser Kumagawa Gaiden.
Sukinasaki initially appears to be a shy girl, approaching but speaking timidly to Misogi Kumagawa when he first transferred into Suisou Academy. This shy demeanor is soon revealed to be a facade; Sukinasaki is actually highly manipulative, using her ability Error Message Plate to control others. Because of her ability, she considers herself the most important in the academy hierarchy, and prefers to work from behind the scenes by controlling those in power as she orchestrates events to further her own desires. Despite her malicious personality, Sukinasaki seems only to desire peacefulness and stability wherever she has planted herself, and does not particularly care who is in charge as long as this requirement is met. As an idol, Sukinasaki is considered to have adapted the best to the music industry, recognizing the commerciality of everything involved. When she gets excited, Sukinasaki has a tendency to strip.
Sukinasaki has short, reddish-brown hair with an ahoge, and light brown eyes. She wears a face mask that covers her set of shark-like teeth. As a student of Suisou Academy, Sukinasaki wears the standard women's uniform of the academy. While Student Council general affairs manager of Suisou Academy, she wore the armband of the Student Council general affairs manager around her left arm. As an idol, Sukinasaki wears a button down shirt with a checkered pattern and a bow, a matching skirt, tights, and a beret.
Sometime during her tenure at Suisou Academy, Sukinasaki chose Aki Jakago to be the Student Council president, and presumably used her skill to make sure the other girl was elected. She eventually enters class 4, in which her seat number is 2.
Good Loser Kumagawa
Sukinasaki is first seen approaching Kumagawa after his introduction as a transfer student into Suisou Academy. Designated as the one to talk to Kumagawa when no one else in the class wants to, Sukinasaki timidly approaches the transfer student, claiming it is best if he goes to meet the Student Council President and Monarch, Jakago. Sukinasaki lets slip about Jakago's skill, Aero Biker, which gives her control over oxygen. She begs Kumagawa to come with her, otherwise the entire class will be punished, to which he agrees. Upon meeting Jakago, Kumagawa mentions what he has heard of her, an act that horrifies Sukinasaki. Aware of who must have told him, Jakago uses her ability to suffocate Sukinasaki, driving the girl to her knees. At Kumagawa's request, Jakago stops, and asks Sukinasaki if she is sorry, to which the other girl tearfully says she is. After Kumagawa leaves, Sukinasaki takes direct control of the members of the Student Council. Declaring that she was the one who made Jakago Student Council president, she labels Kumagawa as too dangerous to be left alone. Removing her mask and revealing a deranged smirk, she declares herself the most important, as her skill allows her to control other skill holders.
The next day, Sukinasaki approaches Kumagawa again, revealing that Jakago has been hospitalized. She then recommends that he become Student Council President, as he has no history with the school. When Kumagawa tries to turn her down, Sukinasaki reveals that she has taken control of all their classmates. Giving in, Kumagawa admits that he has lost to her. One month later, Suisou Academy is shut down, due to the conclusion of the battle between Kumagawa and Sukinasaki, a battle with no winner.
Sukinasaki quickly makes Kumagawa the Student Council president, and joins him as his general affairs manager. One Monday morning, Sukinasaki discovers her hair has turned blonde. Shocked, she rushes to the Student Council room to tell Kumagawa. She explains to him that she did not dye her hair herself, but suspects student Fude Ezumachi is to blame. She explains Ezumachi's history and skill to Kumagawa, and is surprised to see Kumagawa reading a fully colored version of Weekly Shōnen Jump. The pair leave to educate Ezumachi concerning Jump, though Sukinasaki only wants to fix her hair. Sukinasaki and Kumagawa find Ezumachi painting a portrait of Jakago, prompting Sukinasaki to ask why he is painting the one who expelled him. Sukinasaki scolds Kumagawa for his behavior, who justifies himself by saying Sukinasaki's hair is his hair. Sukinasaki tells him her hair is not his property. She is horrified when Ezumachi skewers Kumagawa with palette knives, and is even more disquieted as Kumagawa rises and stabs himself in the eye. When Ezumachi uses the color blue on Kumagawa and stops him dead, Sukinasaki runs to Kumagawa's aid. Wondering why All Fiction is not healing him, Sukinasaki learns from Ezumachi that All Fiction cannot undo damage that was never done; the color blue only made Kumagawa sense bruises and his body reacted. Sukinasaki cries that Kumagawa has lost like always.
Afterwards, Sukinaki carries Kumagawa back to the council room for rest. She watches over him until he wakes up after school. Sharpening her teeth, she theorizes that Ezumachi's powers are not permanent, as both her hair and Kumagawa's jacket have returned to normal. When Kumagawa prepares to meet Ezumachi again, Sukinasaki tells him to leave and let her deal with Ezumachi. He declines, saying that he must stop Ezumachi from controlling the colors of the world's panties. Sukinasaki tells him that reason is not why they are fighting. As they search the school to find him, Kumagawa tells Sukinasaki that Ezumachi has to be punished for lying. Sukinasaki believes he was not lying about leaving on his own and that, without Jakago, he hates Suisou Academy. She reasons that he might have cut up her portrait because he loves her, and asks Kumagawa if he can sympathize with him. Kumagawa replies in the negative, and asks Sukinasaki why she is not supporting Ezumachi, since he has better qualities to be president. Sukinasaki laughs, stating no one is suited to be president. Sukinasaki and Kumagawa find Ezumachi painting the school on the soccer field. Sukinasaki states she only wants a peaceful school. When Kumagawa offers Ezumachi peace in exchange for the power to control the color of panties, Sukinasaki cries in anger that he is contradicting himself. When Ezumachi destroys Kumagawa's shirt, Sukinasaki warns Kumagawa that he is trying to reveal Kumagawa's skin to use the color blue. Sukinasaki watches as Kumagawa erases the colors until the world is only black and white. After the battle, Sukinasaki says that without red, Kumagawa cannot die from blood loss. She smiles under her mask, and asks Kumagawa if he can finally add a victory to his score. When Kumagawa replies that the mark would soon mix and fade, Sukinasaki asks him what he means, and he states that he has lost again.
Kurokami Medaka's Successor Arc
As Oudo Miyakonojou leaves the Hakoniwa Academy Sports Festival, Sukinasaki arrives along with Jyuujika Hachiningatake and Zomeki Furousan. As the three reach the main field, Sukinasaki removes her mask and remarks that, while she had heard there were many strange goings on at Hakoniwa Academy, it is just a normal school: a farm for raising humans.
Unknown Shiranui Arc
Sometime after the school festival, Sukinasaki (topless) and the rest of Kiyoterae perform their song "Toy-Box" at a concert. Afterwards, the trio meet up with Medaka Kurokami and Mogana Kikaijima in their dressing room. Sukinasaki tells the pair that, since Hakoniwa, Kiyoterae have always performed together. Medaka asks Kiyoterae what a song is. Sukinasaki thinks hard about it, then smiles, saying Medaka thinks about some good things. After Furousan makes her remarks, Sukinasaki adds that a song, whether imperfect or not, is like a style to convey feelings between one's self and everyone else. At the end of the academic year, Sukinasaki is among those present at the Hakoniwa Academy graduation ceremony.
Error Message Plate (操作令状, Erā Messēji Purēto): Sukinasaki is able to control others through cards attached to their foreheads. There seems to be no limit to how many people Sukinasaki can control with this skill; at the least, she can control an entire classroom of students at once. As a side effect, those under Sukinasaki's control slur their speech, as if drunk. However, they remain unaware that they are being controlled.
- When translated from kanji, Error Message Plate means Manipulation Orders.
