She has long, wavy, pink hair, coupled with large crimson colored eyes (hot-pink in the Anime) under very light, barely existing eyebrows. She wore a simple pink kimono, covered by a similarly simple white robe that covered her arms in excess. She also had a thin, low-ponytail that was tied using a single small white ribbon.
In the Anime, her fair skin had a slightly pink tint alongside a couple of tear-like face markings similar to Benimaru, supposedly, to go along with her pink colour scheme, with the addition of two fangs that were long enough to slightly protrude out her lips to add to the "ferocious" theme of the Ogres.
After evolution, she took on the appearance akin to a 16-year-old Human girl with a height of 155 cm, looking more refined and beautiful compared to her former cute self. Her horns also became narrower as with all Ogre to Kijin evolutions.
In the Anime, the slight pink tint on her skin is gone, as well as the face markings, and fangs that are small to be only visible when she speaks.
Excelling at weaving, she made herself a new white kimono with simple but graceful red embroidery and red kimono skirt that's held in place with a red ribbon.
Shuna is a gentle and forgiving girl with keen senses. Being raised as a princess she also has a refined and graceful personality.
She is at that age where she is happy to be depended on, hence since she was always sheltered as a little girl in the Ogre tribe, she incredibly happy and content with her current position under Rimuru. Even a bit of responsibility seems to make her happy.
Even so, she is not to be underestimated as she can get incredibly competitive in certain areas too, such as, being appointed as Rimuru's close aide and taking care of him personally. The will to do so is so much that Shuna and Shion unknowingly pull on Rimuru to the point of tearing him in half.
Shuna is also known to lose her cool when Rimuru is disrespected in her presence. She humiliated Reiner when he aggressively approached Rimuru, by knocking him into a wall and "...Reiner was cowering while holding his head with both hands. From his groin, steaming liquid was leaking out."
Shuna is also the type who highly values hard work and slowly gaining experience to get better, which was why she was devastated and found it to be cheating when Shion got 'better' at cooking due to a Unique Skill later on in the story.
After Rimuru arrived at the scene where the Ogres were battling Rimuru's subordinates, she was the first to recognize his mask and come to the conclusion that he was related to the masked Majin that attacked their village with the Orcs.
However, after seeing how merciful Rimuru was being towards them even with his immense strength and the Ogres mercilessly attacking him without any explanation, she was also the first to judge that Rimuru had no relation with their assailant and stopped her brother before they fought to the death.
After the unnamed Benimaru decided to serve Rimuru and they were all about to be named, she was yet again the first to stop Rimuru from doing so due to the huge risks that came along with it. Despite her effort, however, this time, they were named anyway as Rimuru was ignorant of the fact that naming higher ranking monsters depletes significantly higher Magicule from the namer. Even so, things turned out well and Rimuru recovered from his sleep mode within three days, by which time all six of them evolved into Kijin.
Perhaps due to being house-sheltered her whole life, Shuna is very good at cooking, cleaning and weaving, which is exactly what she utilized to be of use to Rimuru as his subordinate. She acquired the Unique Skills Analyst and Creator which complement and optimize her already existing abilities, helping her become one of the key figures in Rimuru's future country's Department of Production. Alongside her, works the three dwarf brothers, Garm, Doldo and Mild, and also Haruna and other Goblinas. It was high because of her and Kurobee that Rimuru's village were able to acquire exceedingly better garments and armor before their battle against the Orc Lord.
While Rimuru went to fight the Farmas Kingdom army alone, Shuna played a key role in erecting and maintaining the barrier around Tempest so as to maintain, if not improve, the probabilities of Shion and the others' resurrection by making sure their souls do not disperse into irrecoverable fragments, as much as possible.
- She enjoys cooking, cleaning, and sewing.
- Just like Shion and Milim, she also harbors intimate feelings towards Rimuru.
- She along with Rimuru and Shion are voted as the three major idols of the monster country, Tempest.
