Background

Su Rui was originally a human from Earth. At some point, he became a pure consciousness entity and later awoke in Terra as the Ark Simulator, able to reside in and assist hosts 1 239.

His first documented host was Ingrid, also called Ren Dong, an assassin connected to the Venice Family in Syracuse. From within her mind, he provided maps, surveillance, target markings, and operational guidance during her conflicts with rival Lineages 1 4 15. Their bond developed into a romantic relationship, and Ren Dong's affection-based materialization progress eventually overflowed 27 28.

The Upper System repeatedly directs or interferes with Su Rui's host transitions. It forcibly returns him to System Space and rigs a roulette selection that places him in Maria Nearl's mind, illustrating that he cannot always determine where or when he manifests 117. His manifestations later become unstable; he fades from one location, appears in Lin Yuhsia's mind, and admits that he can no longer control his appearances 285 304.

Appearance

Su Rui's body and racial traits change with the host or manifestation context. Across these forms, he is consistently described as an unusually attractive young man whose appearance draws attention 27 55 89 108.

• Original identity: human 6
• Nine-Tailed Fox youth form while with Ren Dong 27
• White-haired Drak form while with Talulah 55
• White-haired, red-eyed Vouivre form while with Saria 108
• Silver-haired form with fox traits during his time with Bai Xue 400
• Snow leopard form with fluffy ears and tail in Kjerag 481
• Temporary little sheep form with lamb-like horns while accompanying Eyjafjalla 524 525
• His manifested body is exceptionally durable but physically weaker than a natural Vouivre; he describes it as built more for defense than raw strength 114

Personality

Su Rui is playful, childish, competitive, and intensely interested in games. He favors single-player and customizable games, dislikes online multiplayer, and readily uses cheats or data manipulation when playing 107 181. He can become impatient when bored, but he is also highly focused when a task interests him.

He often frames dangerous situations as games and is attracted to dramatic violence, such as “rivers of blood.” However, he distinguishes allies from enemies, respects important choices made by his hosts, and repeatedly prioritizes the safety of people he considers his own 17 24 190.

Despite his arrogance and bluntness, Su Rui is capable of careful mentorship and quiet domestic care. He teaches hosts without forcing them to depend on him, cooks for companions, tends to injuries, protects vulnerable people, and handles practical chores himself 345 378 503.
