Yomihime is a calm, collected and dutiful person. When her nation was defeated at Ryuumon castle, she remained calm and collected Sakuza's head. Afterwards, she simply noted that unifying all nations was in sight but still a long way off. She also respects strong opponents, as seen when she complimented Hinowa before killing her. She likes to get her job done, regardless of who is her opponent but she dislikes those who want to waste the time of her, such as Moegi where she doesn't want her to fantasize about herself with her lovers and immediately cut to the chase to make preparations as early as possible.
Outside of her duties as one of the Ten Stars and as a general, Yomihime is noted to greatly enjoy sweets and candies as snacks and during her free time, would take special breaks to eat candy whenever she was in her war camps. Yomhime in particular greatly enjoys foods slathered with honey.
Yomihime was present at the battle of Ryuumon castle. She boarded Hinowa's ship to retrieve Sakuza's head. During the following short skrimish she killed Hinowa and several of her men before leaving with Sakuza's head. She later retreated with her remaining troops. Later she took command of assaulting Shiranui Fortress by detaching her first unit that she later learned that it has been wiped out. Commanding herself into the battle, she encounters Hinata and Tobari as she manages to seriously wound Tobari. The sight of Hinata reminds her that she thought Hinowa was killed by her own hands instead now she encounters her daughter.
Having been able to corner Hinata single-handedly and even breaking her sword and Suzumaru's spear, she was prepared to execute her but Akame manage to arrive in time to assist Hinata. She dueled Akame until she uses her killing signature Falcon Sweep, Akame manages to deflect it, in addition, she manages to wound her. Frustrated, Yomihime escapes following the Tenrou Nation and she will remember both Hinata and Akame, willing to take revenge on the next battle.
Skills and Equipment
Yomihime is an incredibly skilled fighter. She easily killed enemy soldiers  and was able to kill Hinowa, a strong fighter in her own right capable of killing seabeasts  and an experienced warrior like Sakuza  by herself, with little effort. However, she remarked afterward that Hinowa was the first person to injure her in battle and the second is Akame.
She possesses exceptional endurance and very sharp senses. She was capable of swimming near the ocean floor for a significant duration of time , and immediately identified the head of Sakuza by smell.
Yomihime was also shown to be very skilled at swordsmanship, notably able to corner Hinata single-handedly while also breaking her sword and Suzumaru's spear with a single stroke. She is also able to parry Akame albeit Akame is slightly more powerful, even with her body taking the effects of Murasame's curse.
During her battles against Akame and the rest of the Elder's Class is was shown that Yomihime's overall sword style resembles Akame's, with her primarily using a single Katana blade and her primarily relying on her immense speed and power to deal quick but powerful strikes at her opponents.
- Falcon Sweep: is Yomihime's sure-kill signature technique that apparently had a guaranteed rate of fatality until Akame managed to parry and counter the move. Unlike Sakuza, her falcon sweep is more powerful even Hinowa cannot withstand her attack.
Yomihime was equipped with a Meihou, a weapon that was made from Danger Beasts. Akame's first weapon barely holds and breaks unnoticed by Yomihime after she retreats from the duel.
Yomihime was born as a half-human and half-danger beast hybrid. Which similarly to The Lord from the Path of Peace who also has the blood of a Danger Beasts running through his veins, grants her several unique powers due to her heritage, particularly giving her the unique ability to manipulate,control and create immensely powerful flames and fire with incredibly high heat from her own body however. Having so far shown to be able to emit powerful flames blasts at her opponents, surround her body with intense fire to prevent her opponents from getting close to her and cover her entire weapon in fire to further enhance her sword attacks. However due to her own disgust at her racial background, she has yet to mastered this power due to her hesitance to use it and as such, using this ability runs the risk of hurting those she doesn't mean to harm such as her own allies during the heat of battle due to her lack of practice and control over this ability.
Yomihime also possesses a mark in her right eye  and is capable of pushing Hinowa back  and later making her explode through unknown means. She remarked that even she herself doesn't know if she's human.
- Yomihime's name could be based on Yomi, Japanese Underworld, and Hime, Princess. Simply known as Underworld Princess.
