The Tragic Truth Behind Wind Hashira Sanemi's Scowl

Those who are fans of Demon Slayer are well aware of the dark backgrounds of its characters. Almost everyone in the series has lost loved ones to demon attacks, especially the Hashira members. From the snake Hashira who suffered abuse as a child to the stone Hashira who was betrayed by loved ones, even the strongest members of the Demon Slayer corps have faced tragedy. However, there is one Hashira who never shows any sadness or gloom, despite his tragic past. Sanemi Shinazugawa, the wind Hashira, is the most menacing, threatening, and hot-headed member of the Hashira, and his life is actually filled with tragedy, though most people are unaware of it.

Sanemi Shinazugawa hails from a humble family who struggle to make ends meet. He lives with his parents and four siblings, and while his mother is kind and loving, his father is abusive. Sanemi's father is fond of drinking and gambling, and when he loses a gamble or is in a bad mood, he takes out his anger on his sons. Sanemi's mother always tries to shield them from their father's wrath despite her small stature. However, when she's not around, Sanemi protects his younger siblings and takes the beating instead.

One day, fate intervenes, and Sanemi's father gets into a fight with the wrong people and dies. While his passing means the family is no longer subject to his abuse, it also leaves Sanemi's mother as the sole breadwinner. As the eldest son, Sanemi steps up and takes on odd jobs to support his mother and younger siblings. Occasionally, his brother Genya assists him, and despite the hardships, they manage to find happiness and joy in life.

One fateful night, their mother failed to return home from work. Sanemi sets out to search for her, leaving Genya to watch over their siblings. Suddenly, a dark figure barges into their home, wreaking havoc and destruction. The siblings are caught off guard by the creature's swift movements and are unable to defend themselves. In a matter of minutes, the creature attacks them without mercy. Sanemi charges into the room, wielding a cleaver, and swings at the intruder. The creature tries to escape through the window, but Sanemi gives chase and puts an end to its rampage. As the dust settles, Sanemi and Genya finally get a clear look at the creature. To their shock and horror, it's their mother. With their mother bleeding out before them, Genya cries out in anguish and accuses his brother of murder.

With this gruesome event forever etched in his mind, Sanemi decides to become a demon slayer and leaves his brother behind.

On a tragic night, Sanemi lost his mother, younger siblings, and became estranged from his brother, Genya. However, what Genya doesn't know is that someone turned their mother into a demon that very night. Sanemi couldn't bring himself to reveal the truth to his brother and instead chose to leave him in hopes that Genya could lead a peaceful life.

This marked the beginning of Sanemi's brutal journey. Armed with knives, hatchets, cleavers, or anything he could get his hands on, Sanemi relentlessly hunted demons. Though he faced countless injuries, his unwavering determination always resulted in successful kills.

Unaware of the existence of the Demon Slayer Corps, Sanemi caught their attention with his actions. One day, he was approached by a demon slayer named Masachika Kumeno, who recruited him into the Corps and introduced him to a master who taught him the Wind Breathing sword technique. Sanemi's talent as a swordsman quickly became apparent, with some even considering him the greatest wind breathing user in history.

Sanemi's rise to fame within the Demon Slayer Corps started with his partnership with Masachika. However, their lives took a dramatic turn after facing off against a certain demon during a routine extermination mission. Little did they know, the demon was actually Muzan Kibutsuji's Lower Rank One. Despite the intense and bloody battle, Sanemi emerged victorious, but sadly, Masachika succumbed to his injuries shortly after.

As a reward for his remarkable feat of killing one of the twelve Kizuki, Sanemi Shinazugawa is bestowed with the title of Wind Hashira by the leader of Demon Slayer Corps, Kagaya Ubuyashiki. Initially, Sanemi finds the title distasteful as it feels like it was given to him in exchange for his dear friend's life. He even goes to the extent of insulting Kagaya, which leads to a minor confrontation with the other Hashiras. However, after having a sincere conversation with Kagaya and spending more time with him, Sanemi realizes his kindness and wisdom. Despite his rough exterior, Sanemi deeply respects and cares for Kagaya's wellbeing.

Unfortunately, Sanemi's past has been filled with physical abuse from his father, the tragic deaths of his younger siblings, and even unknowingly killing his own mother. After parting ways with his only remaining brother and witnessing the death of his dear friend, Sanemi hoped to lead a happy and peaceful life. But life has other plans for him, and the subsequent story arcs will bring more tragedy to his doorstep, leaving permanent wounds on his body, breaking his heart, and taking everything away from him.
