Kokutou

Kokutou is a 16-year-old girl who entered the death game driven by the need to earn money for her own livelihood. Among all participants, she stands as the only player besides the protagonist to have prior experience in such a game—having survived her first run by clinging to a stronger player, a fact that bred an excessive confidence in her own abilities. Inside the 'Haunted House' stage, her sharp instincts led her to discover the escape key before anyone else, yet a moment of carelessness triggered a hidden needle trap, making her the first casualty of that round.
