Saya Hinata

Saya Hinata (born Saya Nagami in 1994) is the younger twin sister of Ema Hinata and the adopted daughter of famous adventurer Rintarou Hinata. Along with her twin, Ema, Saya gains thirteen step-brothers through her father's marriage to famous designer Miwa Asahina.

Appearance
Saya Hinata is a slender girl who maintains a small, short, and premature appearance with a height of 4'11. Her hair is hip-length and light brown, kept tied into twin tails with blue ribbon. Her eyes are wide, innocent-looking and almond shaped and colored. Though freckled around the nose, Saya's skin is milky white and clear. Like her twin sister, Saya wears a school uniform during the day, but she had casual clothes that usually consist of a large sweatshirt/oversized shirt, small shorts, and stockings.Others describe Saya's overall appearance as child-like and innocent, though there is no denying her charm and lovelieness.

Personality
Saya, like the rest of her appearance, is an extremely childlike girl with adorable attributes, though she is not stunted. She maintains a bright and sunny attitude, often seeking attention in a kind and gentle manner. Like her twin sister, Saya hates being a bother and shares in Ema's selfless nature. She is extremely loving and understanding to everyone, including strangers. Unlike Ema, Saya isn't permissive, and she doesn't get embarressed easily, as seen when she walks around the house without clothes on or when she cuddles up to her brothers unabashedly. Though her closeness is due to ignorance and innocence rather than inappropriateness.

Plot
When they were newborns, Ema and Saya's biological parents died. Rintarou took them in, though his work called him to other places all the time, leaving them to grow up along. Saya grew up without the guidance of a parent, and stunted her growth by excessively skipping school and partaking in bad habits (drinking, cigarettes, etc.). She met her best friends, Hatsuharu Roku and Yukio Sotami, when she was twelve and a pervert cornered her in an alley when she was skipping school. The boys saved her and they have been best friends since. Though, because of Saya's almost premature disposition, she had no issue with being inappropriately close to the boys. One day, Saya and Ema discover that their father is remarrying and they will have thirteen new stepbrothers. On the day that they are supposed to meet the boys, Saya stays out late with her friends and ends up meeting them later then Ema. As the girls get closer to their siblings, the boys start to fall for the girls, not as siblings, but as men.

Hinata Ema
Ema and her sister have always been extremely close and loving with one another. Ema is the only person who truly understands and accepts Saya before they meet their siblings, and Saya is the only one who makes Ema feel loves and wanted before they move into their new home. Ema is surprisingly protective of Saya, and Saya is possessive over her twin's feelings.

Hinata Rintarou
Unlike her sister, Saya wasn't bothered with Rintarou's work, and she was never lonely. She always saw Rintarou as a stranger, and he was greatly saddened by this. Though, when he decides to get married, Rintarou makes more of an effort towards a good relationship with Saya.

Hatsuharu Roku
Hatsuharu, along with Yukio, saved Saya from a pedophilic pervert when she was twelve and skipping school. They have maintained a close-knit relationship ever since, and are rarely not together. When Saya turned fourteen, Hatsuharu talked her into a closer relationship, and the two became sexually involved. Hatsuharu views this as simply getting closer together, and it is unclear whether he hold romantic feeling for Saya or not.

Yukio Sotami
Yukio and Hatsuharu saved Saya from an attempted kidnapping and being extremely close to her. They hold this closeness very importantly, though Yukio does not have a sexual relationship with Saya. Her views Saya as an adorable little sister, and is often seen carrying or holding her hand.

Juli
He is Ema's pet squirrel. Saya doesn't speak with him, and regards him as an adorable pet rather than a companion.

Masaomi
To Saya, Masaomi is a confident for her secrets and father-type figure, because she never had one before. He is the first brother she goes to when she's in trouble, and she always asks him questions or opinions first. Suffice to say, Masaomi views her just as closely.

Ukyo
At first, Ukyo is confused with Saya's child-like nature, but he soon comes to love it. The two are often seen curled up together reading books (him, cooking, her, Dr. Seuss). She is the first to comment on Ukyo's romantic fondness for her sister, and he blushingly retorts that she'll always be his favorite.

Kaname
When they first meet, Kaname finds Saya charming, though disarming in her unabashed nature. Later on, hints of romantic interest can be seen when he gets jealous of his brothers calling her attention away from him. Kaname is often seen holding Saya close to him or touching her in some way (usually her hair), and quietly demanding her eyes on him. He is the first to react when she comes clean about her sexual past, both angry and saddened by the revelation. The two begin a romantic relationship after several instances of stolen kisses that Saya personally asks him about. During the inquiry, Kaname comes clean about his feelings, and the two start dating.

Hikaru
Hikaru is the first brother that Saya meets, and she finds him both hilarious and confusing, as she doesn't understand the intellectual jokes he makes about his brothers' affections for her and Ema. The two get along fairly well, but Hikaru is extremely uneasy about how to deal with someone as tiny and innocent as Saya. It is hinted that he has romantic feelings, but Hikaru lets them rest when Kaname makes his feeling known.

Tsubaki
Both Tsubaki and Saya share similar personality traits. And though Saya would like to be closer to the white-haired brother, Tsubaki views her as an obstacle in front of Ema and Azusa, and brushes her advances towards civil relationship aside. By the end, when Kaname and Saya begin a relationship, Tsubaki puts aside his childishness and opens up to her.

Azusa
Saya finds Azusa charming and funny, and is constantly seen jumping onto his back and hugging him by surprise. In return, Azusa called Saya "Little Kitten", and the two share in stories. Azusa sees Saya as a younger Tsubaki, so he's very close to her, and the two are the first to forge a family bond.

Natsume
Like Azusa, Natsume views Saya as a younger Tsubaki, and this establishes an immediate bond. And while Ema meets Natsume later on, Saya stumbles upon the CEO by accident in the park when she's almost assaulted by a pervert. She begins running into him, and two form a friendship, later discovering they are siblings at the wedding. Saya silently roots for Natsume or Subaru to win over her sister, coaching the two and encouraging them.

Louis
Louis finds Saya adorable and charming, though Saya doesn't understand him at all and finds it difficult to be in his presence. The two hardly interact, though when they do, saya leaves the conversation feeling perplexed and stupid. Louis is extremely fond of her despite her confusion around him.

Subaru
When they first meet, Saya finds Subaru's shyness amusing, and finds pleasure in surprisingly hugging him and causing him to go red. Later, when she discovers his feelings for Ema, Saya roots for him and coaches him on how to win her affections. He accepts her as a sibling then, and the two become close friends.

Iori
When they first met, Saya frightens Iori with her closeness. But she soon worms her way passed his defences, and the two become extremely close. Iori makes his feelings known to her when he gives her a rose and an iris from his personal garden, igniting a fight with Kaname. He often steals kisses from Saya, though she believes them to be innocent, getting him into trouble when Kaname discovers the hobby. Though, Iori lets go of his feelings when Saya and Kaname begin a relationship.

Yusuke
Yusuke is Saya's classmate. He generally doesn't associate with Saya because he finds her personality to be abrasive. Though he later opens up to her when she discovers his feelings for Ema and comments on them, giving him advice on what to do nonchalantly because she finds him to be funny.

Fuuto
When they first meet, Fuuto insults Saya, and the comments fly right over her head. Because she's so hard to insult, Fuuto doesn't talk to her, but Saya find Fuuto interesting, albiet rude and obnoxious. Later, when Fuuto gets sick and Saya is the only one who knows, they become closer after she takes care of him. Kaname gets jealous, and Fuuto discovers his older brother's feelings for Saya, playing on them for amusement while silently watching over Saya.

Wataru
Wataru and Saya immediately become fast friends due to their alike personalities. They are extremely close and friendly with each other, often seen cuddling up and hugging freely or bothering the brothers in a tag-team takeover.
