Voice Actress: Elizabeth "E.G." Daily (https://www.youtube.com/watch?v=ehteB3K1Gp4)

Hinoka is the eldest daughter of Sumeragi and Ikona and the second child of four in the Hoshidan royal family. She originally had another sibling whom she was very much attached to. However, Hinoka lost this sibling when they were kidnapped as a young child and raised in Nohr. Furious at her inability to prevent the kidnapping, Hinoka thereafter began training as a Sky Knight around the age of seven. Her natural inclination to be rash and hotblooded often made training difficult for her, a fact only worsened by pegasi only accepting riders whose hearts are calm and not ruled by passion. As a result, she had trouble training her steed over the years, often running into accidents due to not being able to properly handle it. One of these accidents allowed her to meet Azama, who tended to her injuries and helped her to return home. Forming the impression that Azama was a kind and benevolent monk, Hinoka later hired him to serve as one of her personal retainers.

According to Hinoka, she had, over the years, attempted to infiltrate Nohr and rescue the Avatar on multiple occasions, although each attempt was halted by Ryoma and Mikoto.

Though born a princess, Hinoka's personality is nothing typical of one. Serious, determined, and unsophisticated, Hinoka has the spirit of a natural warrior and valiantly charges into battle with utter fearlessness and courage. This spirit of Hinoka's is strongly complemented by her passionate sense of patriotism, one that compels her to personally take up arms in order to defend her homeland and its people from coming under harm. In this regard, she has the tendency to charge headlong into battle with wild abandon, often disregarding her personal safety and the objections of others as she does so. She is known to overwork herself to the point of exhaustion as shown in her support with Hinata.

Ryoma and Hinoka herself note that in the past, she was much more shy and even a crybaby. However, Corrin's kidnapping proved to be a turning point both in her lifestyle and her personality, as their kidnapping was the source of much guilt and regret in her incapability to rescue them, being devoted into becoming a warrior for that sole reason. As a side effect, this caused her to be unintentionally yet considerably neglectful to Takumi, Sakura, and Azura, not spending a lot of time with them due to her constant training, as her supports are possibly the first real bonding time she's ever had with them, causing her to be stunned and regretful when she realizes that Takumi believes she wouldn't care if he died and Sakura thinks they are not alike at all. Despite that, she cares deeply for them, with her supports with Subaki telling that, in the midst of a heavy storm where pegasi couldn't fly, she charged into a forest to look for a lost Sakura with complete disregard for the risks involved.

It is through Hinoka's adamant desire to protect others that a softer side to her personality is simultaneously revealed; she is, at the core, selflessly compassionate, where she values the lives of others more than she does her own, no matter what their social class may be. This is especially evident in her supports with Azama, where, in spite of his protests, Hinoka desperately attempts to salvage the life of a fatally wounded soldier, unreservedly demanding him to lend his healing assistance to her.

She is the most caring person in the army, knowing plenty of soldiers by name and acts with consideration towards them.
