A former freestyle rap battle champion turned rapper and producer, Seo Chul-gu (Xitsuh) graduated early from high school while studying in the US and entered BYU on a scholarship; season 3 coverage introduced him as a rapper who started college at 16. After making his name on Show Me the Money 4 and 5, he moved into survival shows with Penthouse in 2022. His quick reads and all-in commitment on the Bloody Game series earned him the nickname 'human Bloody Game', and he was runner-up on KBS's debate survival show The Logic in 2026. Dead Again is his sixth game survival show and his first by producer Jung Jong-yeon.
