Background / History

Seven Nights conceals her true name, using “Seven Nights” as her name when traveling outside the Demon Realm because demons do not reveal their true names casually. She is the Grand Craftsman's sister and judges demon beauty by the quality of one's horns. 145 229 253

She first confronts Xu Jiang during a Spirit Realm trial. After losing to his Grasp of the Undying, she attempts to recruit him into the demon race by forcing a Demon Mark Skill Stone on him. The Skill Stone instead merges with Qianji, allowing Xu Jiang to use demonic power without becoming a demon himself. 145 146

Her relationship with Xu Jiang gradually becomes a transactional alliance. He supplies Demonic Crystals and uses Demon Mech sacrifices to transfer resources into the Demon Realm; in exchange, Seven Nights provides information, tracking, transportation, and access to demon territory. 193 205 206

Appearance

Seven Nights usually appears as a tall, graceful demon woman with wavy long hair, red lips, an alluring face, and two smooth goat-like horns. Her preferred attire includes form-fitting red dresses, though she also wears dark red scaled battle armor marked with gold demonic patterns. 206 245

• Her horns identify her as a high-ranking demon and are central to demon beauty standards. 172 253
• She can manifest at an enormous scale; one arrival through a spatial rift begins with a sixty-meter-long leg before her full giant form appears. 363
• Her battle armor is worn when she expects combat or must sustain a powerful descended state. 205 245

Personality

Seven Nights is proud, ambitious, and intensely concerned with status. Her stated goal is to become king of the Demon Realm, and she pursues the Demon King Seat to secure the authority and strength needed to protect her territory and retaliate against those who bully her subordinates. 229

She is manipulative and opportunistic, initially trying to convert Xu Jiang into a demon and later bargaining for his resources. Demonic Crystals reliably sway her cooperation, though she resents being treated as someone Xu Jiang “keeps.” 145 206 356

Despite her arrogance, Seven Nights is pragmatic when power is at stake. She sets aside her dignity to accept Xu Jiang's support, calls on him for strategy against the Desolate Dragon, and ultimately works beside humans to stabilize the Demon Realm. 357 363 369

Abilities & Skills

Grand Dark Heaven

Seven Nights' signature ultimate skill is a rule-based power that creates its own domain. Its demonic energy can engulf powerful light-based attacks. 246 319

• Used against Xu Jiang during their first battle to the death. 145
• Can suppress radiance within a domain of black demonic energy. 246
• Xu Jiang's Equality of All Beings can reflect the same rule-based power after it is used against him. 319
• Su Lu is capable of devouring the attack, leaving Seven Nights unable to harm him with it. 370

Demon Mark

Seven Nights condensed the unique Demon Mark Skill Stone, originally intended to turn its user into a demon. 146

• Grants dark-attribute damage and allows recovery of injuries and absorption of Soul Power after killing non-dark beings. 146
• Left a perception mark on Xu Jiang; she can sense when he activates demonic power and project herself to him. 172
• Qianji learned the altered version instead, gaining the temporary Demon Mech form and Soul Power absorption. 146

Teleportation and Dark River Control

Seven Nights is an elite teleportation user, capable of appearing behind opponents in combat and using the Dark River for long-distance movement. 246 370

• The Demon King Seat lets her communicate with the Dark River remotely and draw upon its vast dark power. 363
• She can use the Dark River to bypass travel through the Demon Realm and extract allies from danger. 366
• Drawing more Dark River energy permits sustained skill use, but does not compensate for a gap in direct combat strength. 363

Tracking Spell

Seven Nights can use a tracking spell to summon a three-headed dog and have it locate a target. 242

• Used to trace the jade token's location. 242
• Refused to personally destroy the Black Soul Tree because doing so could provoke the Netherfrost Glacier's specters. 242

Demonic Combat

Seven Nights fights with demonic energy, claws, and high-speed ambushes. 246 370

• Broke through the Black Soul Tree King's defenses after its weakness was exposed. 247
• Can maintain a battle-ready descended form, though she warns that this state cannot last indefinitely. 245
• Is unable to force through a blockade of millions of specters while in her descended state. 246

Equipment / Weapons / Items

• Demon King Seat — Enhances Seven Nights' teleportation, enables remote communication with the Dark River, and supports her Demon King authority. 363 369
• Demonic battle armor — Dark red scales with gold demonic patterns, worn for combat deployments. 245
• Eternal Night Forest map — A crude arrow-based map she drew for Xu Jiang; it cost him 500 crystal shards despite being difficult to interpret. 220

Relationships

• Xu Jiang — Initially her trial opponent and intended demon recruit; later her supplier, strategist, and principal human ally in the campaign against the Desolate Dragon. 145 206 357 369
• Qianji — Received Seven Nights' Demon Mark instead of Xu Jiang, transforming it into Qianji's Demon Mech ability. 146
• Grand Craftsman — Her elder brother; she appealed to him to forge the Demon King Seat. 229
• Mo Duo — A demon-suppressing mech she fears intensely; Mo Duo can absorb darkness and fire and claims it could defeat Seven Nights even in her true form. 287 288
• Desolate Dragon — Her principal rival for control of the Demon Realm; she joins Xu Jiang's campaign to oppose it. 357 364 369
• Gray Umbrella — Enemy who used an imitation of her Grand Dark Heaven, provoking her outrage. 246

Story Role / Major Arcs

Silent Village Trial

Seven Nights battles Xu Jiang, offers him the Demon Mark, and tries to persuade him to abandon humanity. Her plan fails when the Skill Stone is absorbed by Qianji rather than Xu Jiang. 145 146

Demon Pact and Northern Frontier

Xu Jiang repeatedly summons Seven Nights through Demon Mech and sacrifices Demonic Crystals to gain her help. She explains that objects cannot cross between realms normally and directs him to the Grand Craftsman capable of upgrading the Desert Eagle. 193 205 206

Demon King Seat

Seven Nights asks the Grand Craftsman to forge her a Demon King Seat, intending to strengthen her position in the Demon Realm. She proposes using Xu Jiang's lifespan-restoration capability to transport its components between planes. 229

Black Soul Tree Conflict

She assists Xu Jiang against Gray Umbrella and the Black Soul Tree King. Although trapped by a mass of specters, she destroys the Tree King after Xu Jiang exposes its vulnerability. 242 246 247

Demon Realm Campaign

With the Demon Realm destabilized by the Desolate Dragon, Seven Nights relocates her followers, accepts Xu Jiang's offer of human military support, and leads a coalition against the dragon. 356 357 364

Her forces capture eight cities, and the deaths of six Demon Kings clear the way for her elevation to Demon Empress. She remains dependent on Xu Jiang's planning while personally leading the charge. 369

Trivia

• “Seven” is used throughout her territory because she considers naming cities troublesome; nine different cities are all called Seven Demon City. 367
• Demons regard polished horns as formal attire, while Seven Nights finds several human fashion preferences confusing. 242 253
• She considers blood, fear, and recent death to be “sweet air.” 193
• Seven Nights is frightened not only by Mo Duo's demon-suppressing nature, but also by Su Lu's power after witnessing him consume her attack. 288 370
