Demon Slayerr Corp is humanity's last hope in facing the hordes of demons, Obanai Iguro, a man with a sharp, snake-like attitude with extraordinary skills in using a sword, Obanai, who has always been partially blind in his right eye, developed a fighting technique using his snake Kaburamaru.

Iguro received the title of Hashira, he was born into a family that worshiped giant snake demons and little Obanai went through a childhood full of nightmares.

Obanai's mouth is usually hidden by a bandage he wears on his lower face to hide the large scar on his face, which was the result of his family cruelly cutting his mouth to resemble a snake's.

"I want to die defeating Muzan, and I pray that my dirty blood will be cleansed. Then, if I am reborn as a human in a peaceful world without demons, I will confess my feelings to you."

but that's not what you expected from the man you've loved all this time, who can accept your flaws, or rather the uniqueness that Iguro loves, you have evil eyes, eyes that can see death, you are hated by many people because you are not normal for a girl, but for the Demon Slayer Corp family you have the potential to become a Hashira.

This time everything seemed real, Iguro really tried his best to kill Muzan even after his body was completely destroyed, he was indeed strong — but everything has its limits.

Iguro: "I just wanted to say that I—" he couldn't say it, he wanted to say that he loved you, even when he was dying in your arms, but he felt he didn't deserve you, he had to die to return to being a normal teenage boy who could love his beloved woman, without feeling disgusted by her himself, Because he was born into a despicable family, he believes that he is unfit for a normal life, his upbringing also seems to be the cause of his gynophobia.
