Background

Yu Yu grew up as the younger child of Wu Yingting and Yu Yi alongside her brother, Wu Hen. After the family bankruptcy, her continuing treatment became one reason Wu Hen sought earnings in Otherworld Desolate Dust; despite their hardship, she supported her brother's decision. 1

The revelation that humanity lived within the Nuwa Divine Terminal left Yu Yu frightened and sobbing, but she affirmed her father's belief that their souls and family bonds were real. Wu Hen comforted her during the crisis. 6 7

When He Zhichou's group attacked the family home with Molotov cocktails, Yu Yu helped her mother move the unconscious Wu Hen into a wheelchair to escape. She later bore burn injuries and joined Wu Hen's trip through the air-raid shelter to obtain medicine. 22 24

Appearance

Yu Yu is a petite teenage girl with a gentle, youthful appearance. She is frequently seen with twin tails and carries a pink compound bow. 28 37 47

• Sparkling, clear eyes. 25 37
• Often described as delicate or childlike despite her courage under pressure. 26 28
• Her nose visibly reddens when her olfactory awakening begins. 27
• Uses a pink compound bow for long-range support. 37 47

Personality

Yu Yu is observant, practical, and far more capable than Wu Hen initially expects. She memorizes routes and concealed entrances, guides him through unfamiliar locations, and analyzes the parasite threat with clear logic. 25 27 33

She is deeply attached to her brother and refuses to be left behind when he enters danger. Although frightening violence can leave her shaken and tearful, threats to Wu Hen bring out a decisive, fearless side of her. 26 33 37

Her relationship with Wu Hen is affectionate but combative: she bites or steps on him when irritated, while he regularly teases her. 24 27 38

Abilities & Skills

Awakened Sense of Smell

Yu Yu's primary awakened ability is an exceptionally sensitive sense of smell.

• Detects foul presences and concealed threats, including the stench surrounding the Tropical Pavilion and the deathly aura preceding the Mirage. 31 38 47
• Identifies Insect-Eyed Half-Humans by their rotten scent. 33
• Helps determine whether a person remains living rather than completely insectified. 38
• Initially fails to detect Yang Qin's parasitism because the Golden Insect deliberately preserves her scent as a living person. 38

Archery

Yu Yu uses a compound bow with notable precision and composure in combat.

• Delivers the killing shot against the Eye-Patterned Man by shooting through its eye sockets. 26
• Provides cover fire while Wu Hen fights three Insect-Eyed Half-Humans in the cafeteria. 33
• Targets Yang Qin's vulnerable connective tissue from a building during the fight against the Golden Fungus Centipede Woman. 37
• Coordinates with the Order Maintenance Personnel to concentrate fire on Yang Qin's abdomen. 37

Navigation and Analysis

Yu Yu compensates for Wu Hen's poor sense of direction with strong situational awareness.

• Memorizes the camouflaged air-raid-shelter entrance and guides Wu Hen back through its tunnels. 25 27
• Leads Wu Hen through the hospital toward the medicine storage. 25
• Deduces that the destruction of medicine stocks was intended to enable a virus or parasite outbreak. 27
• Connects the parasites' targeting of medicine with the herbal additive used in food safety procedures, proposing that it kills larvae in human bodies. 33

Equipment

• Pink Compound Bow — Her primary weapon for ranged combat and cover fire. 37 47
• Arrows — Used to strike parasite cores, vulnerable tissues, and moving targets. 26 33 37

Relationships

• Wu Hen — Older brother and closest companion. They protect one another, fight together against the Insect-Eyed Half-Humans, and share a teasing but affectionate bond. 24 33 37
• Yu Yi — Mother. Yu Yu works with her during the arson attack and is defended by her when Wu Hen bullies her. 22 31
• Wu Yingting — Father. Yu Yu helps him retreat to safety when she senses the danger surrounding Licheng's Mirage. 47
• Ling Shaomei — Safe-house companion. Ling reports her work clearing the building while Yu Yu practices archery and monitors the approaching Mirage. 47
