Background / History

Xing's original body was destroyed during transmigration. His new body was generated from the template he selected: a child of Kaslana and Shenzhou descent. Because he had drawn Kallen's Stigmata, Kallen Kaslana's genes were forcibly selected as his maternal source. 12

He was found near Fuyun Temple at the foot of Taixu Mountain with no remembered past beyond his name. While awaiting transfer to an orphanage, he encountered Crimson Kite Birds, discovered his Stigmata chain, and was guided to Fuyun Temple, where Feather Crossing Dust granted him fragments of Fu Hua's and Cang Xuan's memories. 2

After becoming involved in the Changkong City incident, Xing fought the unstable Mei, experienced her memories through contact, and began forming bonds with Kiana, Mei, and Bronya. He later enrolled at St. Freya Academy with them and joined the Fire Moth squad. 6 11

World Serpent captured Xing and subjected him to a super-evolution procedure intended to make him a vessel for the Gem of Stillness and improve his Honkai adaptability with Vishnu genes. He accepted the danger in order to avert the Sky Meteor incident, but the Gem ultimately fused with him and could not be removed safely. 24 25 32

After resolving a world-collision mission, Xing met Nangong Youhui and learned that he was a native Order Emissary assigned to a fixed Honkai Branch World. His authority can restore and stabilize worlds, but cannot directly rewrite them. 48

Appearance

Xing's default appearance is that of a small, fair-skinned boy with white hair and red eyes. His appearance is unusually mutable: bloodline balance, Stigmata activation, armor, and Bonded Weaponry can change his hair, eyes, age, physique, clothing, and apparent sex. 1 20 25 83

• Kaslana state — Blue eyes indicate his Kaslana bloodline overpowering his Shenzhou side; this state emphasizes physical strength. 20 353
• Shenzhou Citizen Appearance — A long-haired, white-haired, red-eyed martial artist form associated with his Shenzhou Stigmata. 83
• Yae Xing — An adult male fox form with waist-length pink hair, large fox ears, and a fox tail. 113
• Adult height — Approximately 1.65 meters. 118
• Luming / Chen Xilumeng — A feminine idol identity used after repeated transformations; commonly associated with white hair, fox traits, and heterochromatic red-and-blue eyes. 165 187
• Tri-Fusion Form — Combines red, blue, and purple visual traits with fox elements, chains, gemstone ornaments, and Shenzhou-style robes. 365 366

Personality

Xing is initially described as enthusiastic and gentle, with strong curiosity and an ability to adapt quickly to unfamiliar situations. He is also a capable gamer and enjoys teasing people close to him. 1 2 222

Despite his confidence and frequent playfulness, Xing is not fearless. He openly admits his fear of death, but resolves to keep fighting because he wants to protect his friends and world. 36 He consistently takes responsibility for others, from accepting the Gem of Stillness to healing allies and intervening in disasters. 32 75

His empathy can become a burden. After fighting the Maniacs, Xing suffers guilt and doubts his own motives, particularly when influenced by Kallen's personality fragment. 198 He is fiercely protective of those he considers his own, and threats to them can provoke his most ruthless transformations. 174 345

Abilities & Skills

Bonded Weaponry

Xing's defining ability transforms companions into weapons when their hearts resonate with his.

• The transformed weapon's type depends on the companion. 1
• Xing's appearance, clothing, and temperament change alongside the transformation. 1
• On a first transformation, he receives a fleeting, subconscious impression of the target's memories. 1
• With the target's consent, he can use their abilities and combat experience. 1 9
• Activation generally requires a favorability level of at least 70. 95
• The synchronization is mentally invasive: Bronya's personality was altered by repeated use because Xing's consciousness was stronger than hers. 80

Stigmata and Form Switching

Xing possesses multiple Stigmata and can alter the balance between his Kaslana and Shenzhou bloodlines.

• Kallen's Song is his original Stigmata and the foundation of his earliest transformations. 1
• Yae Sakura is an external Stigmata that provides healing, speed-oriented combat, fox traits, and the Spirit Sword: Cherry Blossom Blizzard. 16 21 108
• Fu Hua: Border Guard grants access to the Crimson Kite Immortal's legacy and Shenzhou-oriented forms. 71 83
• He can alternate between strength-oriented Kaslana, speed-oriented Yae, and Shenzhou martial forms during combat. 83 154 364
• His Stigmata can be sealed or destabilized, temporarily depriving him of Fusion Warrior abilities. 157

Honkai Physiology and Healing

The Gem of Stillness and Vishnu-gene surgery gave Xing exceptional Honkai compatibility and recovery.

• The Gem of Stillness is fused to his body; removing it risks injuring him or causing the Gem to erupt. 32
• He can heal severe injuries, including Welt's exhaustion and Bronya's legs and emotional center. 75
• He possesses high poison resistance, enough to survive poisons that Kiana expected to be lethal. 1
• His body can overdraw itself in prolonged fights, leaving him severely injured or unconscious after victory. 107 108

Taixu Martial Arts and Shenzhou Legacy

Xing inherited techniques, memories, and Divine Keys tied to Taixu Mountain and the Crimson Kite Immortal.

• Learned the Taixu Sword Qi training method through Feather Crossing Dust. 2
• Uses Cun Xin Fist Style, Taixu Sword techniques, Five Elements arts, and the Taixu Grip. 72 83
• His Sword Heart reaches the Dustless realm, allowing him to use Feather Crossing Dust for self-hypnosis. 157
• Can use advanced forms such as Cloud Ink Dan Xin and techniques including Shrink to Inch and Heavenly Movement, Myriad Manifestations. 72 344

Order Emissary Authority

As the native Order Emissary of his Branch World, Xing is responsible for its continued stability.

• His authority specializes in restoring and stabilizing damaged worlds rather than directly altering them. 48
• Resolving world collisions resets the affected world's condition to its state before the collision. 143
• He receives missions through a Guidance Module and is expected to repel intruding entities from colliding Branch Worlds. 73 86

Divine Blessing Barrier Kai

A field-control technique that suppresses and manipulates weaker powers within its range.

• Xing decides whether affected energy is neutralized or transferred. 376
• The barrier restrains opponents and drains their energy while maintaining Xing's control of the battlefield. 376
• It can be broken by opponents with sufficient power or an effective countermeasure. 376

Equipment / Weapons / Items
