Background / History

Xin Luo is a Mermaid Princess described as a once-in-a-century genius of her clan. She grew up pampered and subsequently spent years living comfortably on Sea God Island, where she became its only female Sacred Pillar Guardian Douluo 14 19.

She once exchanged letters with her grandfather, but dangerous sea routes and the loss of messengers to predators eventually ended their correspondence. By the time she revisited her people’s home, they had been out of contact for many years 38.

Bo Saixi recalls that the Evil Orca King had previously fought Sea Witch and Xiao Bai while he was still an ordinary Evil Orca King. The circumstances of that earlier battle are not detailed 16.

Appearance

Xin Luo has long, dark-green hair falling in large curls, sky-blue eyes, and a mermaid tail 14 17 21.

  • Clothing: Wears a small emerald-green top 38.
  • Eyes: Described as large, clear, and normally gentle 10 17.
  • Martial Soul Avatar: Enlarges her body to over ten meters tall; she can sit on the sea and float with its waves 17.

Personality

Lively and innocent by nature, Xin Luo is especially sensitive to Bo Saixi’s unhappiness. Her concern extends beyond her own faction: despite being on opposing sides, she protects Jenny and Yeonnie from the Human-Faced Sea Anemone 14 24.

She is also quick-witted and skilled at bargaining. Her alternating-question arrangement with Ren Tao lets her gather information while exploiting openings for mind reading. When cornered, she appeals to his principles, their lack of a personal grudge, and the consequences of provoking Bo Saixi 17 18 19.

Xin Luo dislikes bloodthirsty combat but retains considerable pride in her royal lineage and guardian position. She surrenders when Ren Tao overwhelms her attack, yet later declares that she would rather self-destruct than submit to forced devouring 19 20.

Abilities & Skills

Mind Reading

Xin Luo can peek into another person’s thoughts, making her questions a means of gathering more information than spoken answers alone provide 17 18.

  • Cannot normally read someone whose spiritual power exceeds hers 17.
  • Exploits Ren Tao’s momentary distraction to glimpse his thoughts 17.
  • Uses carefully framed questions to prompt him to think about the information she wants 18.

Fourth Soul Skill

An unnamed flute-based attack releases invisible soul power through the water 22.

  • Activates quickly and consumes little soul power 22.
  • Severs clusters of the Human-Faced Sea Anemone’s tentacles 22.
  • Is substantially weaker than her eighth and ninth soul skills; the anemone catches and redirects some of its water bursts toward her 22.

Seventh Soul Skill: Martial Soul Avatar

Her Martial Soul Avatar produces a giant form and supports the use of Sea-Calming Divine Melody 17 22.

  • Increases her height to over ten meters 17.
  • Is activated alongside her ninth soul skill when the Human-Faced Sea Anemone presents a mortal threat 22.

Eighth Soul Skill: Sea God’s Power: Binding

Her strongest single-target attack begins with a piercing flute shriek and mental shock, slowing the target’s thoughts before trapping them in a contracting sea vortex 18.

  • Its initial mental attack falls short of Tang San’s Vast-realm mental attacks 18.
  • Against Ren Tao, the Sea God’s Abhorrence makes the surrounding water resist his control and attack him 18.
  • Sea God’s Light from her ring further empowers piranhas and hostile waves, combining physical, energy, and mental assaults 18.
  • Ren Tao breaks free and severs her connection to the Sea Ghost Whirlpool 19.

Ninth Soul Skill: Sea-Calming Divine Melody

An indiscriminate area attack performed through her Black Flute 17.

  • Requires her Martial Soul Avatar and time to gather power 18.
  • Forces Tang San’s concealed group to withdraw rather than risk being caught in its range 17.
  • Sends broad ripples through the sea, creating a restricted zone during her confrontation with the Human-Faced Sea Anemone 23.

Mermaid Bloodline

Xin Luo’s bloodline attracts Ren Tao’s evolutionary devouring instinct rather than merely his interest in her martial soul 18 23.

  • Mermaid genes can help unlock the second stage of his autonomous evolution and prevent mutations 23.
  • Ren Tao obtains what he needs through a connection to her consciousness, using the Human-Faced Sea Anemone as a medium; Xin Luo survives 23 24.
  • The merfolk’s mutation-suppressing power is a bloodline property, not a demonstrated combat technique used by Xin Luo 38.

Equipment / Items

  • Black Flute — Instrument used to perform her offensive soul skills and accompany Ren Tao’s song within the Sea of Inheritance 18 22 23.
  • Ruby ring containing Sea God’s Light — Allows her to leave Sea God Island and detect the Vast Sea Cosmic Shroud through resonance. Its divine light is exhausted after her attack on Ren Tao 18 19.
  • Luminous pearls — Illuminate the coral where she rests while traveling with the Evil Spirit Orcas 20.
  • Storage Pouch — Given to Ren Tao with pearls as payment for investigating her people’s disappearance. The pouch itself is worth more than its contents 38.
  • Dreamscape Skull — An emerald-green soul bone from the Human-Faced Sea Anemone, entrusted to her by Ren Tao to fund purchases of sea products. She considers it precious and admires its potential as a hair ornament 38.

Relationships

  • Bo Saixi — Her elder and a close confidante. Xin Luo worries about Bo Saixi’s lonely future; Bo Saixi later threatens Ren Tao if anything happens to her 14 17 37.
  • Ren Tao — Initially an adversary who wants her bloodline. Their dealings develop into reluctant cooperation, mutual assistance, and an agreement to investigate her missing clan; no romantic relationship is confirmed 19 23 38.
  • Jenny and Yeonnie — Evil Spirit Orcas she protects against the Human-Faced Sea Anemone. They thank her and recognize her as a friend of their group 22 24.
  • Grandfather — A family member she tries to visit after years without contact. Her search instead reveals that her people’s settlement has become a dead sea 38.

Story Role / Major Arcs

Ren Tao’s Duel on Sea God Island

  • Ren Tao singles her out to choose a battlefield for his duel with Tang San, provoking her suspicion that he is trying to divide the guardians 10.
  • His conspicuous interest in her is explained as an involuntary response to her value to his evolution, not proof that he has fallen in love 10.

Interrupted Ambush and Forced Journey

  • Her Sea-Calming Divine Melody disrupts the Shrek Seven Devils’ ambush, giving Ren Tao’s kin an opportunity to withdraw 17.
  • During their exchange of questions, Ren Tao warns that Bo Saixi must sacrifice herself for Tang San’s inheritance and that Tang San will later cause mass battlefield deaths. Xin Luo is visibly shaken 18.
  • After losing their subsequent fight, she reveals that her arrival drove off the ambushers. Ren Tao spares her but pressures her into guiding him toward Tang San’s hunting party 19 20.

Human-Faced Sea Anemone

  • Spider Crab illusions separate the travelers, leaving Xin Luo trapped in an inner-mind illusion while Jenny and Yeonnie shelter behind her 21.
  • She regains control, counterattacks, and holds off the anemone after it isolates the three of them through its spatial techniques 22 24.
  • Ren Tao reaches her consciousness, where an illusion depicts dead and weeping mermaids. His arrival replaces the desolate scene with his Sea of Inheritance, and she accompanies his singing on her flute 23.
  • The experience leaves her unsettled by both her people’s apparent suffering and the realization that Ren Tao’s devouring did not mean killing her 24.

Disappearance of the Mermaid Clan

  • After leaving the orcas, Xin Luo visits her grandfather’s home and finds her people gone. The dead sea resembles the scene shown in the anemone’s illusion 38.
  • Following her return to Sea God Island, she remains silent and listless for several days, alarming Bo Saixi 36 37.
  • She asks Ren Tao to discover where her people went, explaining that the island’s other authorities cannot leave and that she trusts no one else with the task 38.
  • In return, Ren Tao asks her to purchase roughly a quarter of the materials needed for his second evolution stage through merchants supplying Sea God Island 38.

Notable Quotes

“If you're asking for my opinion, I refuse. But if you intend to force me, I would rather self-destruct!” 20

Trivia

  • In an author’s note, the author acknowledges readers’ suggestions to make Sea Witch the female lead but states that a romance storyline has not been decided. She is explicitly described as a positive character who helps the male lead 38.
