However, just as the stream starts, they fall into a warp trap and get transferred to the 95th floor, where S-rank monsters appear. As everyone in the audience prepares for the worst, Jin decides to go all out to protect his sister. His unmatched battle against the S-rank monsters, which no one had ever defeated before, quickly spreads across the internet, going viral.
