how did mitsuri die

Mitsuri Kanroji, the Love Hashira in Demon Slayer, died from fatal injuries received during the final battle against Muzan Kibutsuji, the main antagonist. She fought bravely alongside other Demon Slayer Corps members but succumbed to her wounds after the battle was over. Her exact death circumstances were not shown in detail, but it is known that Muzan inflicted the fatal injury. Before dying, Mitsuri shared an emotional moment with Obanai Iguro, the Serpent Hashira, whom she loved. They confessed their feelings to each other and promised to reunite in the afterlife. Mitsuri's death is considered one of the most tragic in the series because she died without fulfilling her dreams and longing for love, though in the manga epilogue it is revealed that they were reincarnated and married in another life.
