Sanemi

Sanemi and Giyuu are polar opposites personality-wise, but they share many similarities despite so. Both have lost their only family to demons and a best friend who died during a team battle against a demon. Due to their personality differences, they get along quite badly in most of the series and only during/after the final battle do they get along. They're the Pillars who have the most development in their relationship during the series.

Manga/Anime Sanemi and Giyuu are first seen interacting after the battle against Lower Moon 5, during the Pillar Meeting where Tanjirou and Nezuko's fate would be decided. Giyuu is the Pillar who gets the close up of his expression when Sanemi first appears holding Nezuko's box and in the manga he is clearly seen frowning and looking at Sanemi. In the manga, after Sanemi stabs Nezuko, Giyuu is the first of the 3 Pillars to get a close up of his reaction to it, which shows Giyuu frowning and looking away. When Tanjirou defends Nezuko and is about to attack Sanemi, Giyuu interferes and yells 'Oyakata-sama' is about to arrive. This distracts Sanemi and this allows Tanjirou to get a hit on Sanemi. After hearing Tanjirou, Urokodaki and Giyuu will commit suicide if Nezuko hurts anyone, Sanemi says they can die for all he cares but that doesn't guarantee anything. In the preview after the ending of episode 22, the Pillars are commenting on the fact that Sanemi got hit by a rookie, to which he responds that he would've dodged it, had Giyuu not gotten in the way. Giyuu replies to this: "Excuses, excuses." which annoys Sanemi.

Sanegiyuu insult Giyuu insulting Sanemi It's a long time until they interact again, after the fight against upper moon 4 & 5. The Pillars are summoned and they get informed about how to get the Demon Slayer Mark. When Sanemi says it's really that simple, Giyuu responds: "I envy those simpletons who can say this is simple." which pisses Sanemi and Iguro off. When Giyuu says that he'll leave now that Amane is gone. Sanemi tells him to wait, because they have to make their future plans. After Giyuu makes walks to the door to leave, Sanemi tells him to wait and after being asked by Shinobu to explain, Giyuu says that he's not like them. Sanemi gets angry at this and says he's pissing him off and asks if he's making fun of them. Sanemi stands up and goes to Giyuu but before anything can happen, Gyomei interrupts. In this case, Sanemi is angry because he (like everyone else) is misunderstanding what Giyuu means. Sanemi thinks Giyuu thinks himself above the other Pillars, while Giyuu actually means he's not worthy of being a Pillar. This misunderstanding is mainly because Giyuu is hard to read and looking at his facial expressions would make you think he's arrogant, next to that he never corrects this misunderstanding.

Sanegiyuu smile Giyuu smiling at the thought of getting along with Sanemi When Tanjirou goes to Giyuu's estate to train, he walks in on Sanemi and Giyuu fighting. Before the fights begins, Sanemi already looks angry. During the short fight, Sanemi says: "Oraoraa!! What wrong?! You're no different from the rest of us!" because he is still under the impression Giyuu thinks himself superior to the other Pillars. The fight ends when both of their swords break, however Sanemi says it's time to pummel each other to death with their fists. Tanjirou interrupts then and eventually reveals that Sanemi likes ohagi which surprises Giyuu. Sanemi eventually knocks Tanjirou out and after he wakes up Giyuu tells Tanjirou that Sanemi stormed away. He also explains that they weren't actually fighting but taking part in each other's training. When Tanjirou apologizes for interrupting, Giyuu denies this and talks about how Sanemi was mad the entire time and he couldn't get a good talk with him. However Giyuu reveals that he's glad that he found out what Sanemi likes. He explains his plan to sneak some ohagi in a bag and give it to him. Giyuu smiles when he says that he's sure they can get along if he does this. This is very interesting, considering this means Giyuu wants to get along with him and it would make him happy. Giyuu also hadn't smiled before this panel, so that means the idea of getting along with Sanemi is enough to put a smile on Giyuu's face (something extremely rare). While Ubuyashiki (also known as Oyakata-sama or the master) talks to Muzan about all the people that despise him, the panel shows Sanemi and Giyuu on the front, while the other Pillars and Tanjirou are in the background.

Sanemi and Giyuu fighting together While fighting against Muzan, Giyuu's sword slips out of his hand and he gets saved by Iguro and Gyomei. Sanemi throws a sword at him and tells him not to space out or else he'll kill him himself. Giyuu grabs the sword with a twisted expression and then continues fighting filled with determination. After the other Pillars make their blades shine red, Giyuu and Sanemi make their own swords shine red by clashes them together. They're the only Pillars who helped each other make their blades shine red. During the fight, all the Pillars work extremely well together, not once getting in each other's way. This includes Sanemi and Giyuu, who arguably have the worst relationship within the Pillars. When Muzan is at the door of death, Gyomei yells to attack and chip away at his stamina, but Sanemi has a hard time moving and Giyuu suddenly comes in and attacks. Sanemi then follows up with his own attack.

After the final battle, the only 2 Pillars to survive are Sanemi and Giyuu and they attend the final Pillar meeting together. When the children of the previous master bow and thank them, they protest. When they encouraged them the children ended up crying and they look at each other and softly smile. This is another one of the few instances Giyuu has smiled and yet again it has something to do with Sanemi. Sanemi is also someone who rarely smiles outside of battles or out of anger, although it happened more than with Giyuu. In the extra pages for the final volume, there is a picture of the two of them eating together after the final battle.

Sanemi and Giyuu eating together after the final battle Giyuu and Sanemi were possibly the Pillars that got along the least at the beginning, but after the final fight, they are shown to get along well, just like Giyuu had hoped. During the series, while Sanemi hated Giyuu, Giyuu seemed to have no ill will against Sanemi. Giyuu did occasionally somewhat vaguely tease/insult Sanemi, but he never seemed annoyed by Sanemi's rude nature, for example, in one of the extra pages of volume 19, while the other Pillars were scolding Sanemi for his rude behavior, Giyuu was seen in the background with his usual poker face. Next to that, Giyuu just seemed to see Sanemi as a grumpy person, as was revealed in the fanbook. It was also shown that Giyuu actually wanted to get along with Sanemi, although that was one-sided at first, after the battle Sanemi let go of his grudge and they were shown to get along well.

Official Fanbook In the fanbook, the Pillars' impressions of each other were revealed and Giyuu's impression of Sanemi was that he was grumpy/hot-headed, but he didn't say anything about disliking him, but Giyuu's impression of Iguro reveals that he felt sad when Iguro said bad things about him. However both Iguro and Sanemi hated Giyuu and talked bad things about Giyuu. This means that Giyuu perceives Sanemi's hatred of him differently than Iguro's hatred of him. On the profiles of the databook, both Giyuu and Sanemi are chosen to comment on their relationships with the other Pillars, something which was only done by 1 or 2 people per person. But both of them commented on each other. Giyuu thinking of giving Sanemi ohagi in order to get along with him was also chosen to illustrate the relationships between all the Pillars.

Sanemi is also canonically colorblind, whether this was just a metaphor or literal has not been confirmed. But due to the many different forms of colorblindness, with the most common being red-green colorblindness, blue may be the only color Sanemi can see properly. Blue also happens to the color of Giyuu's eyes and the main color for his breath technique/sword.

Some have noted the similarities between this ship and TodoBaku. Both ships involve a hot-head and cool, collected character who's oblivious in social situations being shipped together. They also both went from people who get along badly, to friends and the cool, collected one wanted to eventually get along with the hot-head

Sanemi is a tall man of very muscular build, with spiky long white hair and large almond-shaped eyes framed with long eyelashes; his purple irises also appear to have dark swirls within them. When angered, they appear notably bloodshot. He also has dark patches beneath his eyes, making him appear perpetually tired or restless. His face and body are covered with scars, accrued over his many years of fighting demons. He cuts his hair short somewhere in between the events of the Hashira meeting and the Mugen Train incident. He is usually seen wearing a crazed expression on his face.

He wears a black standard Demon Slayer uniform, tinted dark green in the anime, unbuttoned to expose his chest and abs with a white long sleeved haori over it with the kanji for kill (殺さつ, satsu?) etched on the back, white buckles around his shins and tabi socks with a pair of white zōri with green straps.

During his battle with Kokushibo, he loses his right index and middle fingers.[3]

Due to years of harsh training, Sanemi possesses incredible physical strength. He could lift Nezuko Kamado in her box with a single hand without effort, knock out Zenitsu Agatsuma with a casual strike, break a wooden sword because he swung it with too much force, and cut Tanjiro Kamado's ear with a single kick. He was also able to briefly contend with Kokushibo, one of the physically strongest demons in existence in a sword fight, and was even able to push the demon's blade down by parrying the blow with his own.

Marechi Blood: Sanemi's blood was revealed to be one of the rarest blood types.

When the showdown with Muzan is finally over and time has passed, Sanemi has clearly mellowed out a bit. He is able to smile with Giyu, even after their past confrontations. Most surprisingly, he admits his mistakes and apologizes to Nezuko about his actions. It goes to the point he gives her a smile and a pat on the head, as he sees Genya in the way she responds.

Giyu Tomioka (冨とみ岡おか 義ぎ勇ゆう, Tomioka Giyū?) is a major supporting character of Demon Slayer: Kimetsu no Yaiba. He is a Demon Slayer of the Demon Slayer Corps and the Water Hashira (水みず柱ばしら, Mizu Bashira?) of the Taisho era.[5]

Appearance Giyu is a fairly tall young man of a lean muscular stature and pale complexion, who is almost always seen wearing a stoic expression. He has choppy raven-black hair of uneven lengths, with jaw length side-bangs, a low messy ponytail at the base of his neck, and bangs falling over his eyes in a choppy fringe. His eyes are sharp and moderately large, having irises a lapis blue color, and their pupils a navy blue, sometimes having his irises completely opaque and empty, just in lapis blue color, and are framed by thin eyebrows.

Giyu wears a black standard Demon Slayer uniform, tinted in charcoal color in the anime, consisting on a button-up jacket with golden buttons, stand collar and long sleeves, a white belt, and a tattsuke hakama pants wrapped by white kyahan, having a pair of white zōri with dark blue straps and tabi socks underneath being the same color as his uniform. Over this, Giyu wears a haori that's split down the middle into two different halves: the right one in a carmine color, and the left one in a geometrically patterned rhombi prints, in green, dark green, orange, and yellow. These haori were later noted to have belonged to his late older sister, Tsutako Tomioka, and his deceased friend Sabito.[6]

During his battle with Muzan Kibutsuji, he loses his right arm.[7] After the fight, Giyu cuts his hair down to neck length, and he is seen wearing a button-up collared shirt under a kimono, and umanori hakama pants.[8]

While Giyu was training under Sakonji Urokodaki, he wore a dark red haori which would later make up his current one as well as black tucked-in tattsuke-hakama pants and his current white leg-wrapped kyahan and pair of white zōri with dark blue straps. In addition, he also wears the warding masks that are signature to Sakonji's pupils. For Giyu, it is a white fox mask with light blue eyes.

Giyu is a man of strong equanimity, always wearing a calm and stern expression on his face. Having a stoic personality, and possessing a very strong sense of justice and responsibility, he had no tolerance towards those who don't know their own limitations and throw away their lives.[9] Despite letting Nezuko Kamado live due to Tanjiro Kamado's determination, he shows zero hesitation when killing other demons and has no respect or mercy towards them like most Demon Slayers.[10] Even so, Giyu violated the Demon Slayer Corps' code of conduct without hesitation to protect Nezuko during Shinobu's attempt to kill her. This implies that he doesn't completely despise demons as some other Hashira do, and is willing to make an exception for a demon by letting them live if they don't kill and eat humans. This shows that he is more pragmatic and impartial in dealing with demons rather letting his hatred cloud his judgement.

Due to his aloof personality, Giyu is not close to his fellow Hashira. While some are on even terms but emotionally distant from him, others view him with apathy, or even disdain; Sanemi Shinazugawa and Obanai Iguro were particularly contemptuous of the Water Hashira due to unfoundedly misreading his aloofness as arrogance. Giyu also expressed surprise when Shinobu Kocho mentioned that he is hated by the others; despite this, he remains on good terms with her, with both having a great deal of history together. In the end, after defeating Muzan Kibutsuji, he ended up developing a closer friendship with both Tengen Uzui, and his former rival Sanemi.

He is of very few words and isn't very good interacting with others, choosing to observe from a distance quietly.[11] He even goes out of his way to tell Akaza that he hates talking and wants to keep his name to himself, as he thinks names are not meant to be shared, especially to demons. He could also be quite sardonic as shown when he frankly berates Inosuke Hashibira for mistaking Father as a member of the Twelve Kizuki, and sarcastically insulting Sanemi for complaining that the way to achieve a Demon Slayer Mark was simple. However his quiet behavior could become a detriment to Giyu's reputation, as the Water Hashira did not explain his deeper emotional feelings with his colleagues, and uncooperatively declined explaining his reasoning to not particpate in Hashira Training, angering Sanemi and Obanai, and even causing his closest ally Shinobu to ask Giyu to explain himself.

Beneath his seemingly unemotional and aloof attitude, Giyu suffers from an inferiority complex which he developed since his participation in Final Selection. This self-doubt in himself caused him to initially refuse to participate in Hashira Training due to in his words "not being like [the Hashira]", and it reached the point where he contemplates abandoning his position as the Water Hashira until Tanjiro helps him realize that instead of acting on his survivor's guilt, he should cherish his life and live on for the people who sacrificed their lives for him.[12] This feeling of survivor's guilt strikes again when he believes Tanjiro has died after the fight against Muzan. Giyu, while he sheds tears, admits how he is always the one who is saved.

Despite his stoic nature, Giyu is shown to be protective and caring towards those he is close to and considers his friends. This is first shown when he puts his life on the line for Tanjiro and Nezuko by vowing to commit seppuku if the latter were ever to eat a human.[13] Giyu has been shown to lose his composure and usual stoic demeanor when those he cares about are in danger, as seen when he is greatly angered by Akaza's attempt to kill Tanjiro and visibly shocked when he hears the news of Shinobu's death. This is further shown in the fact that he still wears half of Sabito, his late best friend's, and his older sister's haori as a memento of them. However, Giyu appears to be particular in who he shows emotions for, as he doesn't appear to react at all when informed of the passing of Genya Shinazugawa and Muichiro Tokito.

Despite this, Giyu will not let his personal relationships get in the way of his duty. When Tanjiro begins his assault as a demon, Giyu is the first to announce that they need to take him down, despite his brotherly-type relationship with Tanjiro. Following the death of Muzan Kibutsuji and the eradication of demons for good, it is clear that Giyu has been able to embrace his happier side, shown by his smiles towards the Kamado siblings and even Sanemi, which shows how much their combative relationship has slowly developed into one of mutual respect.

In his childhood while training under Sakonji Urokodaki, Giyu is shown to have a much more cheery disposition, even after the tragic loss of sister. This can be attributed to his friendship with fellow trainee Sabito, as the two were very happy in each other’s company. After Sabito’s death during Final Selection, Giyu flies into a depressive episode. By Giyu’s own commentary, he admits to wanting to stifle this memory to prevent his tears, implying that a reason for his emotionless persona was to prevent himself from grieving that way that he did following the death of his friend.

Omegaverse, also known as A/B/O (an abbreviation for "alpha/beta/omega"), is a subgenre of speculative erotic fiction, and originally a subgenre of erotic slash fan fiction. Its premise is that a dominance hierarchy exists in humans, which are divided into dominant "alphas", neutral "betas", and submissive "omegas". This hierarchy determines how people interact with one another in romantic, erotic and sexual contexts.

Alpha (α): socially (and in some interpretations, even biologically) dominant, physically built, short-tempered and a natural leader;

Beta (β): depending on the story, they are regular human beings, or have a mix of Alpha and Omega traits, or their own unique traits;

Omega (Ω): submissive and gentle, calm and a peacemaker.

Omegaverse fiction typically focuses on wolf or other canid-like behavior in humans, especially as it pertains to sexual intercourse and sexuality, which is described as instinctual, responding to animalistic physiological stimuli. This includes rutting and heat cycles, pheromonal attraction between Alphas and Omegas, penises with knots (used to "knot", or tie, the partner to an Alpha during copulation, an action known as "knotting"), scent marking, imprinting, breeding, mating rites, pack structuresnand potentially permanent psychic bonds with a mate. Between Alphas and Betas, only females can carry on a pregnancy, but male Omegas are often envisaged as being able to become pregnant via a uterus connected to the rectum, and Alphas can impregnate regardless of their main gender. To make penetration and impregnation easier, male Omegas often have self-lubricating anuses.

Since Omegaverse is a type of folksonomy, some of its aspects are included or excluded at the discretion of the story author. Sometimes Betas are absent, or other intermediate designations such as Deltas and Gammas are added. The genre often features other fantasy elements, such as the presence of werewolves or other fantastical creatures. Some works introduce a rigid caste system, where Alphas are depicted as the upper class elites while Omegas are at the bottom tier and face discrimination and oppression because of their physiology, creating an example of biological determinism. In darker stories, this results in non-consensual or dubiously consensual intercourses, forced pregnancies, kidnapping of Omegas and sexual slavery.

Giyuu does not have a right arm (he lost it in the final battle). Sanemi lost his right index and middle fingers. After the final battle both of them lost some muscle which is more prominent in Giyuu. Giyuu now has a more feminine shape than before, his hips are more prominent. They no longer wear demon slayer uniforms, instead they wear more common clothing (yukatas, kimonos, etc.) for their time period (~1920 Taishō era Japan). Sanemi has a 7 inch cock.
