Background

Lei lived in Utopia on Bancipis with his sisters, Truth and Ying. Unknown to him, Truth made a bargain with [War] to give Lei a chance to awaken as a Nix; [War] subsequently altered Lei's memories and turned Bancipis into a trial planet for a Nix Holy War 415.

When Lei returns to Utopia and finds it reduced to scorched earth, he desperately searches for survivors, particularly Truth 371. His grief and rage initially leave him unable to act decisively, prompting Bai Sheng to force him into harsh training and demand that he choose whether to pursue revenge 373 374.

Lei later learns that Ying, whom he initially believes to be Zhen, is his other sister. Though their confrontation exposes Ying's role in Utopia's tragedy, Lei ultimately lets her leave rather than kill her 378 379. After learning more of Truth's fate and [War]'s manipulation, he resolves to confront the Progenitor and avenge his sister 386.

Appearance

Lei is a tall young man, described as around 1.8 meters tall. His brown hair can hang over and conceal his face during moments of distress or confrontation 367 372.

• Brown hair.
• Taller than Bai Sheng, who is described as under 1.5 meters 367.
• Carries his Battle Device and later keeps the head-boomerang at his waist 405.

Personality

Lei is straightforward, optimistic, and willing to trust others; he invites Bai Sheng to join Bancipis' liberation effort after seeing his capabilities 359. He forms deep bonds with his monsters and treats them as companions rather than mere tools 354.

The destruction of Utopia leaves him vulnerable to anger, confusion, and self-pity. Bai Sheng's severe training pushes him to replace that stagnation with determination, and Lei gradually learns to fight with patience and strategy rather than relying only on force 373 374 407.

His strongest motivation is his family. He risks his life to save Truth's soul and restore Gomora's body, while also showing concern for Ying when she is injured in battle 388 412. Even after discovering Truth's deceptions, he empathizes with the circumstances that forced her choices 415.

Abilities & Skills

Nix Power

Lei possesses Nix power, a derivative of [Emotions] Path Energy. His power strengthens through bloodline awakening, training, and inheritance of [War]'s legacy 374 395 416.

• Can temporarily seal his own hearing to resist sonic attacks 395.
• Can exchange positions with surrounding rocks to evade attacks 395.
• Reaches a level Bai Sheng compares to that of a powerful Pathwalker, though still below Yan Qing in actual combat ability 386.
• Manifests a horned, silver-white Nix form after inheriting [War]'s power 416.

Awakened Battle Device

Lei's Battle Device stores and summons his monster companions. Following his bloodline awakening, it can also serve as a versatile close-combat weapon 354 374 377.

• Can transform into a double-edged short sword or light blade 377.
• Can deploy a small light shield for defense 377.
• Generates four golden chains capable of binding an opponent 377 378.
• Stores the head-boomerang later discovered within its internal space 398.

Tactical Combat

Lei adopts Bai Sheng's “retreat to advance, play it steady” approach: creating distance, identifying weaknesses, and coordinating his own attacks with Gomora's overwhelming pressure 407.

• Uses the head-boomerang for rapid strikes, throws, and defensive blocks 407.
• Disarmed the Dark Armor, seized its black longsword, and exploited the armor's weak points 407.
• Used strategy with EX Gomora to exhaust EX Red King's magma energy before defeating it 417.

Monster Companions

• Gomora — Lei's principal combat monster. Uses the Super Vibration Wave, can burrow rapidly, and fights in close coordination with Lei 358 395 407.
  • Became stronger following Lei's bloodline awakening 374.
  • Was transformed into EX Gomora through Lei's inherited power and a Stellar Core 416.
  • Defeated EX Red King and later reverted to its ordinary form 417.
• Litora — A flying monster used as Lei's mount and scout. Its Battle Device avatar can transmit its field of view to a virtual screen 354 393.
• Pegila — A powerful winged monster capable of using ice-based attacks and helping extinguish large fires 354 371.
• Antora — Subdued after Gomora overwhelmed it; later assists the group by building their shelter 374.
• Destrudo — A monstrous Stellar Core entity acquired by Bai Sheng, but included among the forces Bai Sheng identifies as part of Lei's side 387 398.

Equipment

• Battle Device — Cube-like device with three monster slots and a side card slot for monster summoning 354.
• Head-boomerang — A sharp, balanced weapon that appeared inside Lei's Awakened Battle Device; later reacts to the force calling him toward [War] 398 405.
• Black longsword — Temporarily taken from the Dark Armor and used to breach its defenses 407.

Relationships

• Bai Sheng — Friend, mentor, and ally. Bai Sheng trains Lei, pushes him to overcome despair, and later helps him oppose [War] 359 374 416.
• Truth — Lei's sister. Her bargain with [War] enabled Lei's awakening, but placed her soul at the center of [War]'s scheme 412 415.
• Ying — Lei's sister, whose existence was hidden from him for years. Their relationship begins in hostility but develops into cooperation against Destrudo and [War] 379 388.
• Gomora — Lei's closest monster companion and primary battle partner; the two demonstrate strong synchronization in combat 354 407 417.
• Carnisa — A fellow Nix who trains and fights alongside Lei. She recognizes his growing strength and supports his battles against external threats 370 407.
• [War] — The manipulative Lord of Annihilation who orchestrated Lei's trial, sought to take his body, and was ultimately deceived by Lei 412 415 416.

Story Role / Major Arcs

Bancipis and Utopia

Lei introduces Bai Sheng to the workings of a Battle Device and his monster companions while pursuing the liberation of Bancipis 354 359. The destruction of Utopia then becomes the central catalyst for his desire to uncover the truth and seek revenge 371 373.

Training and Awakening

Under Bai Sheng's harsh instruction, Lei's awakened bloodline, Battle Device, combat instincts, and teamwork with Gomora improve substantially 374 376. He later applies these lessons to defeat the Dark Armor without accepting direct assistance from his allies 406 407.

Nix Holy War

Lei and Ying face Destrudo as part of his “graduation assessment,” with Bai Sheng intervening only to protect and guide them when needed 387 388. Lei continues toward Planet Polis, intending to confront the Progenitor and uncover the truth behind Truth's fate 386.

Ascension Stairway to Godhood

[War] isolates Lei from Gomora and manipulates him with the promise of restoring Truth's soul and Gomora's body 412. Lei endures the stairway's trials, learns the truth from Truth, feigns obedience to [War], inherits the legacy's power, and joins Bai Sheng in destroying the stairway 413 415 416 417.
