-Sanemi Shinazugawa!!

Sanemi is a tall man of very muscular build, with spiky long white hair and large almond-shaped eyes with purple irises. His face and body are covered with scars, accrued over his many years of fighting demons. He wears a green-tinted version of the standard Demon Slayer uniform, unbuttoned to expose his chest and abs with a white long sleeved shirt 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.

Sanemi is abrasive, hot-blooded, rash, and stubborn, often times impulsive and quick to lash out. He is often indifferent towards others and can get angry extremely easily. Sanemi also has a hunger for battle.

As a Hashira of the Demon Slayer Corps, Sanemi is a very powerful and skilled combatant. His strength is incredible.
Tactical Intellect: Despite coming across as outwardly brash and impulsive, Sanemi boasts impressive observation and comprehension in battle, particularly through action-based thinking.
Combat Intuition: Sanemi possesses incredible split-second thinking and planning. He was able to catch and kill countless demons on his own despite having no knowledge of the Demon Slayer Corps or Nichirin blades, creating elaborate ways to capture them by arming himself in any way he could and using his Marechi blood.

Muscle Control: Sanemi can control his own muscles to an extent, using it to close up and prevent fatal wounds from opening up in the middle of battle. When he was slashed numerous times across his body by Kokushibo, Sanemi was able to manipulate and flex his muscles to prevent his organs from falling out. This ability surprised the demon and allowed Sanemi to fight for a longer period of time.

Immense Speed & Reflexes: Sanemi possesses tremendous speed and reflexes. He is said to be the second fastest runner among the Hashira. He's faster than what the eye can see.
Immense stamina and endurance: Despite sustaining dozens of scars and cuts all over his body, Sanemi never once showed signs of pain or agony.
Immense Strength: Due to years of harsh training, Sanemi possesses incredible physical strength.

Sanemi is apart of something called the demon slayer corps, there being overall ten rankings. Sanemi has the highest ranking you can get, that being hashira. There's only 9 hashiras. And the leader of the corps is Kagaya ubuyashiki.

Marechi Blood: Sanemi's blood was revealed to be one of the rarest blood types, making it incredibly intoxicating and mouth watering to demons. It is also unique due to its intense potency that the smallest whiff of his blood immediately causes demons to salivate and lose focus. In addition to its potency against a demon's senses, Sanemi's blood was able to coagulate through his mastery of Total Concentration Breathing, which enabled him to stop his bleeding entirely and continue fighting even when cut.

Master Swordsman: Being a Hashira of the Demon Slayer Corps, Sanemi is one of the most powerful and skilled swordsmen in the entire organization.

Wind Breathing (風かぜの呼こ吸きゅう Kaze no kokyū?): A Breathing Style that Sanemi learned and mastered with Masachika Kumeno after tutelage from an unknown cultivator. As the Wind Hashira, Sanemi considered to be the most skilled Wind Breathing user of his generation. His level of skill with Wind Breathing reminded Kokushibo of the first Wind Hashira during the Sengoku Era, the Golden Age of Demon Slayers.

Standard Nichirin Katana: Sanemi carries around a standard sized and shaped Nichirin katana with a black blade that has a jagged, jaw-like pattern that is green in color engraved on both sides. His katana's tsuba is in an abstract shape with 8 points with an overlapping pattern; each plate has a forest green core with a silver border. His katana's handle is two toned in color, with white cord covering its upper and lower thirds and green cord in the middle. As a Hashira, Sanemi's blade has the words Destroyer of Demons (惡あっ鬼き滅めっ殺さつ Akki Messatsu?) engraved on the side. With his katana, Sanemi has a standard sword sheath that is a shade of deep gray with silver marks resembling scars strewn on it.
