Yui, the fifty-sixth child of Shirona of the Snow Village in Mount Iwaki (岩木山雪里白那の五十六子結 Iwakiyama Yukisato Shirona no Gojūroku-shi Yui?) or simply Yui (結?), is Akira's older twin brother. He was the former chief of the Snow Village in Mount Iwaki and the former user of the nil calculus.
Apperance[]
Unlike his twin brother Akira who has a feminine-like appearance, Yui has a more masculine appearance. He has dark blue hair that reaches just above his shoulders and blue eyes. He has thick eyebrows which accents his intimidating aura. He wears a green fur hooded jacket with grey fur on the hood, dark blue pants and dark brown shoes with darker brown soles and toes.[4]
When he was in Okinawa working at Granny's Diner, he wore his hair slicked back with a headband, along with a short-sleeved shirt featuring a design on the chest, rolled-up pants, black fingerless gloves, and flip-flops.[5] However, after leaving the job, he returned to wearing his usual outfit, keeping only the fingerless gloves.[1]
During his childhood in the Snow Village, he wore a simple white kimono and footwear that appeared to be made of straw. After leaving the snow village, he started wearing his current outfit. Since he was using the power of the Nullstone, it became embedded in his chest.[6]
Personality[]
In his first appearance, Yui comes across as a cold, emotionless individual, displaying signs of apathy and an antisocial personality. This is evident when he mercilessly freezes a group of boys to death after asking them where his twin brother was. Upon reuniting with Akira, he exhibits an even more robotic and hollow demeanor, blindly obeying his every whim as long as it ensures his safety. This highlights his extreme protectiveness, though in a disturbingly possessive and unhealthy way.
Later, it is revealed that his empty and nihilistic personality—with the exception of his only grounding center, Akira—is a result of the Nullstone’s effects. In exchange for enhancing his already powerful cryokinetic abilities, the stone reduced him to nothing more than a hollow shell of his former self, leaving only fragments of what once drove him to attach to the Nullstone—his younger brother, Akira. The stone’s influence turned Yui hostile, attacking indiscriminately anyone who dared to separate him from Akira. His complete lack of remorse for wiping out his village and imprisoning his brother within an ice palace he created himself indicates that his sense of morality had been entirely erased.
In the past, Yui was a responsible and mature older brother, willing to sacrifice his own freedom and happiness to shield Akira from the harsh traditions of their village. At one point, Yui was brought to see his father, the village’s previous Yuki-onoko, and was horrified by the man's deteriorated state and fragile mental condition. Fearing that his brother would suffer the same fate, Yui volunteered to become the village chief in his place. However, the immense weight of his responsibilities and the constant feeling of powerlessness gradually drove him into a state of emotional instability, filling him with resentment and hatred. His moral compass became increasingly warped, leading him to develop an obsessive fixation on purity and corruption—believing that Akira was something pure that had to be protected at any cost.
After being freed from the Nullstone’s influence, Yui becomes calmer, more solemn, and sincere, showing genuine remorse for his past actions. Although he carries deep guilt for everything he has done, he expresses respect for those who stopped his rampage and begins to understand that he does not have to bear his burdens alone—especially with Akira by his side.
History[]
In the snow village of mount Iwanki, Him and his twin brother, Akira, were born. It has been said that a male Yuki-onna in their village is born once every hundred years. When growing up, the two would go near the barrier that protects the village but, kept getting caught. In a magazine Akira found on the mountain, he and his brother found about the Inugami detective agency and Tokyo.
When the women of the village are deciding which of the twins should be chief, Yui volunteered to be it as he didn't want Akira to suffer. As chief, he would have sex with the women to make sure the village survived. One day, his brother thought he had wet the bed and burned it as he didn't want the others to find out. This worried Yui as his brother didn't wet the bed but, has started ejaculating.
He asked the women of the village to let out of the barrier and promised them he would impregnate all of them if they accepted his request. They agreed and Yui talked to his brother as they are going near to the barrier. He told him that he was leaving the village too but, as they are getting close he left him. Before he was completely out of Akira's line of sight, he told him to go to Tokyo, find the kemono office, and they will see each other again.

Later, Yui would go to the place where it posses the Nullstone that created the barrier for the snow village to escape the women. He had enough and put the Calculus in him, wiping the village in the process. As the calculus possessed him, he only remembers what was important to him, his brother. Leaving in search of him and he was later reunited with him.
Powers & Abilities[]
Because Yui is a Yuki-onoko he possesses the powers the species are known for.
- Cryokinesis: Yui has the power to control and create ice. His cryokinetic abilities are noted to be much more stronger and precise than his twin brother, Akira, greatly alluding to either his natural talent or due to the effects of the Nullstone he was attached to. His craftsmanship is immensely detailed and stunning, where he managed to create an elaborate ice palace for Akira to live in, and create subsequent complex types of furniture such as a bed and a bathtub. His abilities in combat outclass Nobimaru in terms of raw power alone, able to spawn bursts of ice in his vicinity to ward off any attacks and counter-attack in the shape of huge, ice spikes that penetrate his enemies, killing numerous clones of the Kitsune in the process. He is also able to create more elaborate combat gear, such as an innately detailed kabuto helmet and a pair of vambraces and gauntlets, as well as using a pair of block-shaped ice to aid him in combat both defensively and offensively. His main method in fighting is to freeze his enemies into living ice statues, killing them in time due to hypothermia if they aren't sufficiently thawed. Nonetheless, his powers may be formidable at the beginning, but he also has a time limit, shown when he collapsed on his knees and remained motionless, due to the effects of the Nullstone having caught up onto him despite his resistance to cold and slowly sapping his life away.
Skills[]
- Culinary Skills: Yui acquired his culinary skills while working at Granny's Dinner in Okinawa. Her Yakisoba is very popular among the girls there.[5]
Relationships[]
Akira[]
He is Yui's younger twin brother. Since they were young, Yui loves his brother and cares for him greatly, protecting him from harm even from their own clan. As his mental health started slipping down, he clung desperately to the peace and stability that his bond with Akira provides, even to the point of unintentionally giving his younger brother an inferiority complex by saying "Never do anything but smile". When he learned that he is deceived and the women discussed how Akira is most likely dead, he snapped and destroyed the village in retaliation. Even when swallowed by the overwhelming power of the Nullstone, Yui held onto the things important to him, which is his younger twin brother. Upon getting a wake-up call from Akira and being reminded of the promises they made to each other, his bond is rekindled with him once more, to the point where Akira follows him in the first half of his self-reflection journey.
