Iguro Obanai

One of the nine masters of the Guisaldae, and also known as Saju (蛇柱). He uses the snake breath derived from the breath of water.

He has white skin, layered semi-long black hair, and snake-like eyes with odd eyes. His different eye colors are natural, with his right eye being yellow and his left eye being blue.[9] There are many mentions in the work that his eyes are pretty. This is why the snake goblin liked Obanai, and it is said that Muichiro, who has a relatively low reaction rate, was surprised when he found out that Obanai had odd eyes. Tengen also envied him, saying that he was very gorgeous.

With a height of 162 cm and 53 kg, he is very small compared to the other male members.[10] He is shorter than Tanjiro and Zenitsu, who are in their mid-teens, and 5 cm shorter than the female owner Mitsuri. If you think about it, you can see that he is quite short, but Mitsuri is actually much taller than both the Taisho era male standard and the current average Japanese adult female standard.

He wears a haori with black and white stripes. The bandage he wears is to hide the scar on his mouth. He also has a regular uniform and a uniquely shaped Ilrin sword.

Along with Sanemi, he is the most notorious for his foul personality. He is not very friendly by nature, and he always swears at everyone except for Mitsuri, whom he has a crush on, and Kagaya, whom he respects. He is ranked second after Sanemi in terms of people who are difficult for the members to talk to. He also shows strong hostility towards men who approach Mitsuri. He also has a hatred for goblins that is on par with Sanemi.

However, unlike Sanemi, who was so violent that he caused many incidents and accidents, there is no description of him causing trouble due to personal reasons. The only time he acted harshly was when he subdued Tanjiro by pressuring his lungs during the trial, but even then, unlike Sanemi, who tried to cause direct bloodshed, he had the justification of trying to prevent Tanjiro, who was a criminal at the time, from running wild.

His uniquely twisted personality is only superficial, and his actual personality is surprisingly very kind, and his relationships with the main characters are smooth except for one person.[11] His relationships with Tengen and Kyojuro, who have completely different personalities and atmospheres, are also good, and he has a good conversation with Muichiro, who is far from interpersonal relationships in many ways.[12] According to the fanbook, he is the friend he gets along with the most.

He says that he still hasn't overcome his fear of women due to his past memories, and since most of the female members of the Ghost Squad have stories, he says that they are difficult for him in another way. The reason he became so reckless is because his self-esteem hit rock bottom due to his miserable past, and even after becoming the main character, he is still suffering from PTSD due to being tied down by his past.

Like other states, his camaraderie is also strong. He is not the type to approach easily, but he has his own sense of pride and responsibility as a lord. Shinobu also said that he got the impression that although he speaks harshly about Obanai, he actually cares deeply about his comrades more than anyone else.

Iguro Obanai is the best technician in the Demon Slayer Corps with excellent fighting sense and intelligence. His curved trajectory swordsmanship is the result of his precise swordsmanship and extremely honed techniques. He has excellent sense with great speed.

Although he is relatively weak due to his confinement during his childhood, he is strong enough to decapitate a goblin, and his technical skills make up for this, making him stand out even among the strongest line of the Demon Slayers.

The ichirinto used has a handle like a Japanese sword, but the blade is in the shape of a flamberge, winding like a snake. Like a flamberge, it is a double-edged sword, not a single-edged sword. It is said to have been made by Gantetsu, the son of Tetchikawahara Tetschin. The color of the ichirinto is blue-purple.

As it is a unique knife, its scabbard is also a special product that opens and closes using magnets.

He is a user of the snake breath derived from the water breath. He uses a unique sword technique that curves like a snake's orbit based on his swordsmanship technique. As one of the lords who hates goblins the most, he trembled saying that all the goblins who died to Obanai were painful.

Type 1 Wii Begi: A technique that involves a large horizontal cut. Wii (委蛇) is a Chinese character that means 'winding shape'.

Type 2: The fangs of the slashing sword: A technique that involves turning once, slashing from the side, and then cutting from the rear.

Third type of twisting: A technique to quickly attack and strike the opponent's side.

Type 4: Twin Swings: A technique that moves in an instant and slashes the opponent. Unlike other techniques, it has a double-headed snake shape, perhaps because it attacks twice at once.

Type 5: Full-scale Strike: A technique that advances while sliding along a curved path and cuts down multiple enemies at once.

Kanroji Mitsuri: He said that he fell in love at first sight because she was more beautiful than anything he had ever seen in the world, with her pure and clear personality and approaching him in a friendly manner, unlike any other woman he had ever met. Kaburamaru also bit Obanai in a panic. He said that when Mitsuri was embarrassed by her uniform and didn't know what to do, he gave her socks as a gift.

It is said that they have been eating together often since then[25] and even exchanged letters. Judging from the fact that Mitsuri is happiest when she is with Obanai, it seems that they have feelings for each other.

Kaburamaru: This is the only pet that Obanai opened his heart to, as he suffered from distrust of humans due to relatives who did not seem like family. Kaburamaru is very intelligent for a snake, and follows Obanai's orders well.

Shinjuro Rengoku: He is the person who saved me when I was almost killed by a snake demon. For Obanai, who was born into a family of only women and was locked up since birth, he was probably the first man he had ever seen other than himself, and he was like a father figure to him.

Rengoku Kyoujuro: The son of a benefactor. It is said that he liked Kyoujuro a lot, even in private, and highly regarded his unique positive personality.

Tomioka Giyuu: Even though they are the same age and in the same state, they don't get along well. The reason is that he doesn't like the look of his unique misfortune on his face. He also made fun of Tanjiro and Nezuko during the trial.

Shinazawa Sanemi: A friend who has been on good terms since the first time they met. They are the same age, live in the same state, and have something in common: a strong hatred of goblins. They both hate Giyuu too. However, their tastes in the opposite sex seem to be complete opposites.

Uzui Tengen: A person I respect. He said that he came to respect me because he had the chance to talk about his past and his face never darkened even though it was not a bright past.

Tokito Muichiro: He felt sorry when he heard the news of his death in the final stage, and he learned the method of manifesting Muichiro's sword through a crow that saw his sword. He was the youngest among the lords, so he wished he could live, and it is said that he sometimes had good conversations with them.

Kochou Shinobu: Judging from the fact that they sometimes talk about swordsmanship or say that she is a hard worker, their relationship is somewhat businesslike, but it seems like they have a pretty good relationship. Judging from the fact that Mitsuri often goes to Shinobu for relationship advice, it seems like she knows about their relationship as well. The two of them have something in common: they treat others with attitudes that are the complete opposite of their true selves due to painful memories from the past.

Kamado Tanjiro: They weren't on good terms to begin with. They were tangled from the very first time they met, but if you think about the fact that Obanai was the one who stopped Tanjiro from moving when the verdict was being handed down regarding Nezuko, you'll get the answer.

Kamado Nezuko: Obanai, who hates goblins just as much as Sanemi, also cannot tolerate the existence of Nezuko, who is a goblin, but unlike Sanemi, he does not directly threaten Nezuko, so it seems that Tanjiro does not have any ill feelings toward Obanai. However, from his perspective, it would have been difficult to tolerate Nezuko because she is a 'woman + goblin', which is a trauma switch. Since he did not meet Nezuko after the Juhyo Trial, no other changes in his perception are depicted.

Cousin Sister: When Obanai himself escaped from prison when he was 12 years old, all 50 members of his family, excluding Obanai himself and his cousin, were killed by the snake demon. She shamelessly criticized Obanai, saying, "If you had just been a sacrifice, your family wouldn't have died!" However, it is said that he continued to worry about his cousin, who was the only one among his family members who survived. Later, he found out that his cousin had gotten married and had children with the remaining property and was living well. When Obanai heard this news, he was glad that he was living well, but he was also envious of his audacity and fearful of his cousin living in the house where the massacre took place, as if he had no concern about his bloodline or how he had amassed all that wealth.
