Name: Obanai Iguro Gender: Male Rank: Hashira (Serpent Hashira) Birthday: September 15th Age: 21 Height: 162cm Hobbies: Senryu, haiku, watching candy craft being made for hours Favorite food: Shredded kelp (Tororo konbu) Style: Serpent Breathing Personality: He has a difficult personality, generally neither trusting nor expecting anything from anyone other than his master, Kagaya Ubuyashiki, and his fellow Hashira. He is an eccentric man who interacts with others using sarcasm and irony; Mitsuri Kanroji describes his way of speaking as "persistent and nagging." In scenes where he speaks, the sound effect "nagging" is often written. On the other hand, while he might seem like a loner who lacks cooperativeness, that is not the case; he is close enough to Mitsuri to exchange letters privately. He seems to harbor feelings for her beyond just being comrades, gifting her thigh-high socks, warning Tanjiro not to "talk so familiarly with Kanroji" during Hashira Training, and taking the lead to protect her from minor demons during the battle at the Infinity Castle. Like Sanemi Shinazugawa, he holds the belief that "demons can never be trusted and must be exterminated without question." This stems from his serious nature and respect for the harmony of the organization; he views poor conduct or a lack of awareness as a Hashira as a disruption to the Corps. Consequently, he is strict in pursuing those who violate squad rules. Additionally, he does not enjoy eating and is the smallest eater among the Hashira, able to go three days without food. This is related to his upbringing.

Name: Mitsuri Kanroji Gender: Female Rank: Hashira (Love Hashira) Birthday: June 1st Age: 19 Height: 167cm Hobbies: Cooking, undefeated at Menko Favorite food: Sakura mochi Style: Love Breathing Personality: She is incredibly prone to falling in love, possessing a mysteriously maiden-like sensibility where she gets excited and heart-fluttery over every little thing people around her do, such as: "Iguro-san, you're as persistent as a snake as always. So tenacious and wonderful!" "Tomioka-san, all alone in a far-off spot, how cute!" "Shinazugawa-san, you have even more scars, how lovely!" "Shinobu-chan looks angry. That's rare. How cool!" This applies to the same sex as well. When Tanjiro asked why she joined the Demon Slayer Corps, she replied, "To find a gentleman to spend my life with!!" She became a demon-hunting swordsman specifically to find a wonderful marriage partner. According to her, she likes "men who are stronger than me" and she "became a Hashira herself just to meet the other Hashira, who are strong but hard to encounter." While it is a lovely wish for a woman of marriageable age, it is a reason that seems wildly out of place for joining a place as grim as the Demon Slayer Corps and risking one's life, leaving Tanjiro extremely bewildered by her answer.
