Background / History

Lin Yu was originally a twenty-first-century man who was pulled through a vortex while playing a mobile game. He awoke in the Dragon Ball World as a low-power Saiyan infant who had landed in a remote forest on Earth. Vados found, adopted, and raised him; without her intervention, he believes he would not have survived. 1 11

Over the following eighteen years, Lin Yu matured into a Super Saiyan Six. He later formed relationships with Bulma and Lazuli, then became the host and leader of the Myriad Worlds Chat Group. 1 2

When Shiho Miyano revealed through the chat group that she was trapped in a gas chamber, Lin Yu used his daily free purchase to obtain a teleportation talisman and entered the Conan World to rescue her. He defeated the Black Organization guards, located a safe destination through his aura-based perception, and took Shiho into his protection. 3 4

The Many Children, Many Blessings System bound to him after his marriage to Shiho, granting the Horse and Dog Talismans and Perfected Ultra Instinct. The system panel also identified Vados as one of his wives, revealing the true nature of the woman who had raised him. 11

Lin Yu later traveled to Universe 6 with Vados, fought Champa at her request, and defeated him after a battle that devastated surrounding celestial bodies. 24 27

Personality

Lin Yu is confident, impulsive, and openly proud of his strength. He frequently treats overwhelming power as a practical solution, whether rescuing Shiho, defeating criminal threats, or confronting Champa. 4 10 25

He is intensely protective of the women he considers “his people.” Threats against Shiho, Ran, Ai Haibara, or Akako provoke immediate and often lethal retaliation. 4 10 38 47

His protectiveness is selective. During the Beika Municipal Building disaster, he chose to save Ai Haibara, Ran, and Sonoko but deliberately declined to rescue other civilians. 18 19

Despite his domineering combat behavior, Lin Yu is affectionate and deferential toward his partners, particularly when Ai Haibara is angry with him. He describes accommodating one’s wife as respect necessary for a harmonious family. 16 17 23
