Background

Before transmigrating, Bai Yuze was a hardcore otaku dissatisfied with the plot of Classroom of the Elite. A glowing copy of the novel appeared in his darkened room; after he tested it with his wooden Lake Toya sword, touching the book rendered him unconscious. 1

He awoke on a bus in an altered version of the novel's world, where Advanced Nurturing High School had become a university. Newly received memories established him as a Class A student, while his prior knowledge let him immediately recognize Kushida Kikyo and other characters. 1

During the bus incident, Bai Yuze alone noticed the old woman's abnormal transformation. He intervened against Koenji Rokusuke, survived the woman's massacre by concealing what he knew, and recovered a vermilion sphere from her discarded skin suit. 2 3

After his first death at the school, the sphere activated and returned him to an earlier point in time. The subsequent events confirmed that he had absorbed the object, later identified as a Gui Dan. 6 7 9

Appearance

Bai Yuze is described as reasonably good-looking, though his fixation on novels, anime, and merchandise gives him a conspicuous “dead otaku” aura. 1

• Keeps a wooden Lake Toya sword, originally purchased after watching Gintama. 1
• Bears three unexplained slash-like marks on his left wrist during the Rules Horror trial. 16 17
• Sustains injuries frequently in the Minzhai, including an impaled palm during his battle with the Male Corpse. 44

Personality

Bai Yuze is cautious, analytical, and highly aware that supernatural rules and apparent evidence can be manipulated. He often conceals his knowledge by acting harmless or foolish, believing that drawing attention is dangerous. 3 43

He is also vindictive and pragmatic. Following his resurrection, he immediately exploits Kamuro Masumi's shoplifting to coerce her into helping him retaliate against the student responsible for his death. In the Minzhai, he is willing to deceive hostile entities, use monsters against one another, and treat enemies as expendable tools. 7 30 48

Despite his ruthlessness, Bai Yuze becomes increasingly invested in his companions' survival and growth. He protects Yukino and Yuigahama, uses humor to reduce tension, and bluntly challenges Yuigahama's tendency to leave every decision to others. 33 37 45
