Background / History

Demon Blade Princess was drawn by Luo Ziyan long before Mo Shiyu obtained Xia Yuan. As Luo's ace SSR, she helped establish Luo's status as Gardenia Spiritmaster High School's prominent “big sister” figure. Xia Yuan became interested in her because her name and appearance resembled a character from games in his previous world. 71 73

During the Peak Tournament, she faced Xia Yuan on the twenty-fourth floor. Her Space Slash successfully bypassed his Limitless Technique and cut him in half, though Xia Yuan survived by turning into light. Pressed by his Gate of Babylon, she awakened into Other-Soul Dream Envoy rather than surrendering. 108 110

Xia Yuan ultimately restrained her with the Chains of Heaven and eliminated her from the tournament, but she accepted the defeat with satisfaction and promised to challenge him again. She later continued seeking rematches despite fully recognizing the immense gap between them. 112 114 201

On the East Sea Highway, Demon Blade Princess and Luo Ziyan were trapped by the world-class bounty BOSSES Order and Dantai Yanan. Xia Yuan arrived to save them, but Bomber Requiem later killed both Demon Blade Princess and Luo Ziyan. Xia Yuan resurrected them after defeating Bomber. 263 268 269 272

Appearance

Demon Blade Princess is a tall, slender woman with snow-white skin, an alluring yet graceful build, and an aura of lethal sharpness. She is consistently depicted carrying a long demonic katana.

• Deep-purple hair, usually tied in a high ponytail reaching toward her ankles. 41
• Blood-red, narrow eyes that are often emotionless in battle. 108
• Wears either a red floral kimono or a black-and-red patterned battle dress. 41 108
• Her katana emits an eerie red glow in her normal state. 108
• In Other-Soul Dream Envoy, her hair becomes crystalline amber, her katana turns gold, and her eyes become heterochromatic—one yellow and one green. 110

Personality

Demon Blade Princess is quiet and direct, usually communicating in only a few words. Despite her intimidating murderous aura, Luo Ziyan regards her as gentle, reliable, and obedient enough to restrain her master when necessary. 72 73

She is a battle fanatic who treats powerful opponents as opportunities to surpass herself. Defeat does not discourage her; instead, it strengthens her desire to fight again. Even while restrained and defeated by Xia Yuan, she immediately vowed to keep challenging him. 112

Her willpower is a defining trait. She awakened while severely wounded under Xia Yuan's bombardment, later continued challenging him despite the disparity between SSR and UR power, and accepted each loss as a lesson in swordsmanship. 110 201 298

Abilities & Skills

Master Swordsmanship

Demon Blade Princess specializes in extremely fast, close-range katana combat. Her attacks are difficult to predict, and she can launch consecutive slashes from multiple angles. 108

• Possesses exceptionally high physical attributes and single-target damage.
• Uses agile, ghostlike movement to pressure opponents at close range.
• Her ordinary slashes can carve massive fissures through the Contract Spirit Arena. 108
• Even Xia Yuan acknowledged that her swordsmanship was “divine,” despite his own poor sword technique at the time. 108

Heaven Slash: Demon Blade Cry Ultimate Art — Space Slash

Her signature ultimate cuts through space itself.

• Bypasses conventional physical defenses, including Xia Yuan's Limitless Technique. 108
• Interrupts an opponent's casting; it stopped Xia Yuan's incomplete Domain Expansion. 108
• Split the arena space itself and cut Xia Yuan in half during their tournament match. 108
• Its heavy recovery cost disrupted her defensive rhythm after use. 110
• Became ineffective against Xia Yuan once he could reliably turn into light. 109 110

Other-Soul Dream Envoy

Demon Blade Princess's first awakened state, achieved by binding herself and her demon blade through mutual curses while maintaining balance within their destructive force. 110

• Instantly restores her injuries through spiritual-power consumption upon awakening. 111
• Greatly improves her speed, strength, and agility. 111
• Allows her to evade dense Gate of Babylon bombardments with exceptionally nimble footwork. 111
• Changes her fighting style from a two-handed grip to a casual one-handed grip. 111

Hundred Blossoms in Full Bloom

A wide-area awakened sword technique.

• Releases golden sword energy that blooms like a fleeting flower. 111
• Knocked aside a barrage of Noble Phantasms from Gate of Babylon. 111
• Created an opening for her to close the distance against Xia Yuan. 111

Demon Blade Secret Art: Hundredfold Slash

An awakened rapid-slash technique.

• Generates hundreds or thousands of overlapping blade shadows. 202
• Covers the battlefield in crisscrossing blade energy capable of tearing up the arena floor. 202
• Failed against Xia Yuan's Causal Reversal, which returned the damage she inflicted. 202

Heaven Slash: Demon Blade Cry Secret Art, Second Form — Draw Slash

A charged draw-slash that gathers momentum through high-speed movement around the target.

• Its accumulated force cracked the arena's protective barrier before the blade struck. 203
• Its trajectory sliced an empty building's spire and split clouds in the sky. 203
• Was neutralized when Xia Yuan used Appearance Transformation to turn the demon blade into rose petals. 203

Equipment / Weapons / Items

• Demon Blade / Katana — Her primary weapon; a long blade with an eerie red glow in her normal state. 108
• Golden Demon Blade — The transformed version of her weapon in Other-Soul Dream Envoy. 110

Relationships

• Luo Ziyan — Contract Spirit Master and longtime companion. Demon Blade Princess protects and restrains Luo when necessary; the two fight side-by-side against overwhelming enemies. 72 263
• Xia Yuan — Rival and overwhelmingly stronger opponent. Xia Yuan respects her courage, while she repeatedly challenges him to improve herself. 110 112 201
• Mo Shiyu — Luo Ziyan's childhood friend and Xia Yuan's contractor. Demon Blade Princess is part of their wider social circle and later visits Xia Yuan's villa with Luo. 71 273

Story Role / Major Arcs

Imperial Capital and National Tournament

Demon Blade Princess accompanies Luo Ziyan during Mo Shiyu and Xia Yuan's visit to the Imperial Capital. Her initial interest in Xia Yuan quickly develops into an outright challenge after sensing his strength. 71 73

In the Peak Tournament, she is presented as one of the strongest SSR competitors, with single-target damage comparable to former champion Alucas. She fights Xia Yuan without hesitation, lands the first known Space Slash through his Limitless defense, awakens mid-battle, and is eventually defeated. 108 110 112

Repeated Challenges

Following the tournament, she repeatedly challenges Xia Yuan in pursuit of improvement. Her first rematch lasts only minutes against Gate of Babylon, but she continues returning even after Xia Yuan becomes a UR spirit with rule-based abilities. 114 201 203

During one Kunlun Arena rematch, Xia Yuan allows her to attack before using Causal Reversal to reflect her damage. Demon Blade Princess then attempts a decisive Draw Slash, only for Xia Yuan to transform her weapon into rose petals. She accepts defeat rather than denying the difference in their strength. 202 203

East Sea Highway Crisis

Demon Blade Princess and Luo Ziyan encounter Order and Dantai Yanan on the East Sea Highway. They stand together against Order's domain despite the overwhelming pressure, but are unable to escape until Xia Yuan arrives. 263 264

Bomber Requiem subsequently kills both of them. Xia Yuan resurrects them after the battle, restoring Demon Blade Princess to active status. 269 272

Later Sparring

Demon Blade Princess continues sparring with Xia Yuan after her resurrection. Xia Yuan defeats her again but identifies a specific flaw in her blade intent: the third frame of her opening movement. 298

Trivia

• Xia Yuan initially suspected that Demon Blade Princess might be the same character from a game in his previous world, but could not confirm it. 71
• Her battle style is described as “one blade breaking ten thousand techniques.” 95
• Xia Yuan considers her a “real hardheaded girl” because she refuses to retreat from strong opponents. 107
• She feels reverence as well as battle intent toward Saber Alter, judging its killing intent to be far heavier than her own demonic aura. 266
