Formerly humanity's strongest SSS-rank Volt Assassin, Si Chen witnessed the total extinction of the human race under the tyrannical conquest of Demon King Wrath. Granted a second chance through temporal regression, he awakens ten years in the past as an impoverished college student armed with the primeval Gluttony System. Cold, calculating, and relentlessly pragmatic, Si Chen operates with zero tolerance for corruption, guild politics, or threats directed at his family. His supreme directive is the absolute subversion of the coming demon apocalypse through limitless power accumulation, the reclamation of his parents' erased legacy, and the establishment of an unassailable sovereign faction. Powers: Master of the Gluttony System, allowing him to absorb high-tier demon cores and switch freely between specialized classes. Key combat forms include: Volt Assassin (SSS-Rank Base): Extreme lightning speed, lethal dual-blade assassination techniques, and high-voltage burst strikes. Purgatory Rakshasa: Demonic physical empowerment, bloodlust aura, and overwhelming melee devastation. Bone King: Bone Reclamation, skeletal manipulation, high-density armor formation, and defensive ossification. Soul Requiem Illusionist: Mental disruption, sensory collapse, and psychological mind-breaking. Auxiliary: Exquisite Demon Core passive, Beastbind Teleportation, and dual-wielded A-rank Lightning Daggers.

The younger sister of Si Chen, Si Yun spent years enduring emotional, financial, and physical hardships following the mysterious disappearance and death of their Awakener parents. Forcing herself to abandon her artistic passions to work degrading part-time jobs, she remained the emotional anchor for her brother prior to his regression. Following Si Chen’s temporal return, she is placed in an elite fine arts academy and provided complete security. Beneath her gentle, artistic exterior lies an unyielding resilience and a fierce loyalty to her brother, sharing his determination to dismantle the abusive relatives who stole their rightful heritage. Powers: Non-combatant civilian possessing latent spiritual sensitivity; protected 24/7 by the mythical star-beast Leo and Si Chen's spatial Beastbind security arrays.

The elite President of the Lingyu Academy Student Council and heir to the prestigious Imperial Guild. Blessed with natural S-rank combat potential, Gong Ting initially embodies aristocratic arrogance and rigid institutional obedience. However, during the lethal B-rank Mutated Lair crisis, witnessing Si Chen's unparalleled prowess and fighting alongside him shatters his vanity, revealing a core of genuine martial honor. Rather than stealing credit for the clear, Gong Ting publicly announces Si Chen's sole supremacy at the graduation ceremony, breaking ranks with his corrupt guild to become a key allied pillar. Powers: S-Rank Vanguard Awakener; master of heavy high-tier elemental sword arts, kinetic vanguard shields, advanced martial combat arrays, and frontline command leadership.

The brilliant director and chief technological strategist of the Mithril Trading House. Exceptionally perceptive with an eye for generational genius, Qing Zhi immediately discerns that Si Chen is far more than a standard college Awakener when he presents high-tier demon collateral. Functioning as Si Chen’s primary arms dealer, financial backer, and intelligence broker, she supplies advanced anti-demon radar apparatuses, specialized weaponry, and underground liquidity to fuel the foundation of the Black Raven Guild. Powers: Master strategic intelligence analyst, high-level arcanotech engineer, and economic mastermind possessing vast underground supply chain networks and customized anti-demon sensory tech.

A mythical star-type cosmic lion cub discovered and liberated by Si Chen from the high-gravity trials of the extradimensional Demon Tower. Bound to Si Chen through an ancient Astral Contract, Leo acts as both a formidable combat companion and the ultimate invisible guardian for Si Yun. Despite his cub-like appearance when resting, Leo possesses ancient celestial lineage and devastating combat instincts. Powers: Astral Beast Physiology; cosmic star-energy manipulation, dimensional displacement, spatial blink/teleportation, beast-rend claws, and high-speed elemental kinetic tracking.

The catastrophic sovereign of the demonic legions whose descent in the original timeline eradicated human civilization and killed SSS-rank Si Chen. Wrath embodies pure, apocalyptic destruction, commanding millions of mutated abyssal fiends and tearing open planetary-scale rift portals. His future arrival serves as the ticking clock driving every single action, recruitment, and power ascension Si Chen undertakes. Powers: Calamity-tier Demonic Sovereign magic, planetary rift generation, abyssal hellfire manipulation, supreme life-force corrosion, and near-invulnerable demonic physical armor.

A depraved, wealthy young master backed by deep underworld connections and the Black Mountain Society. Accustomed to using family wealth and mercenary violence to subjugate whoever he desires, he targets Si Yun after she rejects his advances. His predatory entitlement triggers Si Chen's full, merciless retribution. Powers: Low-tier Awakener relying exclusively on inherited wealth, private military contractors, and Black Mountain Society assassins.

The corrupt Director of Academic Evaluations at the National Awakened University and an entrenched political operative for legacy guild interests. Terrified by Si Chen’s anomaly during evaluation core testing, Gong Xuan actively attempts to suppress, downgrade, and sabotage Si Chen's academic rank to preserve the monopoly of elite guild heirs. Powers: Mid-tier Awakener wielding institutional administrative authority, bureaucratic suppression protocols, and rigged grading cores.

A ruthless A-rank rogue Lightning Assassin who operates under deep cover within public dungeon exploration parties. Posing as a weak, unassuming recruit, Volt Lei baits dungeon parties into lethal encounters before murdering his teammates to loot their equipment and high-tier monster cores. He makes the fatal mistake of choosing a dungeon party containing Si Chen. Powers: A-Rank Lightning Arts; high-speed electro-daggers, concealed shadow-step assassinations, lightning-burst cloaking, and treacherous party-wiping tactics.
