Lin Hai

Biodata

Power Progression

Background and History

Lin Hai came from a technologically less advanced world where Star Rail was a game. After receiving a package of ten Lucky Stars, he squeezed one and unexpectedly summoned Firefly to his home. Their round trip established a connection, and a panel identified her as his contract target. He then summoned Sparkle with a second star 1 14 65.

His travels brought him to Belobog’s Underworld, where he saw its shortages firsthand and began supplying food, medicine, and necessities. Working with Seele and Wildfire, he expanded the aid effort into a project to rebuild the Underworld’s air circulation system 10 25 47.

After confronting Cocolia and fighting the Engine of Creation, Lin Hai gained de facto control of Belobog. He envisioned turning the city into the foundation of a future Galactic Empire 60 62.

Appearance

Lin Hai is a young man with short black hair 32 86.

• For his wedding, he wore fitted black attire embroidered with subtle silver patterns resembling a river of stars 150.

Personality

Lin Hai is playful and willing to meet teasing with a challenge, as shown when he reversed Sparkle’s attempt to pin him against a wall. He is also protective of the people close to him: he promised to find a cure for Firefly and fought to defend an injured Sparkle 2 18 77 80.

He openly desires power but initially acknowledged that he was no paragon of virtue and resolved to avoid becoming like Homelander. As his strength grew, he became more confident and increasingly regarded money as a tool rather than an end. His ambitions expanded from helping the Underworld to building a new order across the stars 10 49 68 76.
