Xiachi is a student at South Jin College. He's very smart and has a keen eye to spot patterns even in dire situations.
He is dating Qingzhi, the school's idol, and because of her he joined the Deductive Reasoning Club.
When Qingzhi disappears, he and his friend Mengqin are the only ones who can remember her, so they start to search for clues on her whereabouts. While looking for her, they end up entering the Telencephalon, a game where people put their lives at stake.
