Background / History

Columbina appeared in Xu Tianming's spiritual sea alongside Mavuika when he awakened his twin Martial Souls. She recognized him as the Traveler through the Lunar Moment Force, though her control over that power had greatly weakened after arriving on the Douluo Continent. Unlike Xu Tianming, she and Mavuika initially lacked physical forms and were tethered to his Martial Souls. 1

She learned from the moon that her strength and authority could recover as Xu Tianming grew stronger and obtained soul rings. Xu ultimately renamed the Silver Moon Martial Soul associated with her the Frost Moon Martial Soul. 2 4

During the hunt for Xu Tianming's second soul ring, Columbina offered to guard his mental sea against spiritual attacks. Her moonlight barrier enabled him to endure tests of mental pressure far beyond normal limits and later protected him against the soul shock of a ten-thousand-year Magic Flame Wolf soul ring. 8 9 27 28

Columbina gradually came to view Xu Tianming as family. After he asked her to treat him that way, she admitted that she did not know how family members interacted and accepted Mavuika's offer to teach her. Xu Tianming later began calling her “Yaya,” a nickname she shyly accepted. 14 20

Appearance

Columbina has the appearance of a frail, delicate young woman with a quiet, moonlike presence. Her eyes are usually closed beneath a hollow-carved blindfold. 1

• Wears a moon-white short skirt. 1
• Has a soft voice and a gentle temperament. 1 8
• Her face flushes easily when confronted with unexpected intimacy or affectionate nicknames. 1 20
• Her eyes are described as newly opened during her conversation with Xu Tianming about becoming family. 14

Personality

Columbina is gentle, considerate, and unusually calm even in dangerous circumstances. When Xu Tianming asked to test the limits of her mental defenses, she understood his caution and reassured him that she was not offended. After a momentary lapse in her defense injured Xu Tianming's mental sea, she immediately strengthened the barrier, soothed his injuries, and apologized. 8 9

She is compassionate toward others. Her perception of Ye Guyi's distress helped prompt Xu Tianming and Kong Deming to intervene against the Holy Spirit Cult, though Columbina carefully avoided directly demanding that they help. 14

Despite possessing vast inherited power, Columbina is inexperienced with ordinary intimacy and family dynamics. She innocently joined Xu Tianming and Mavuika's embrace in an attempt to understand whether it was something family members did, and later stated plainly that she enjoyed holding Xu Tianming. 14 23 24

Abilities & Skills

• Can communicate with the moon for information and guidance. 2 26
• Her full power is associated with the Authority of the Three Moons. 2 27
• Her current authority is incomplete. 26

Mental Sea Defense

Columbina creates moonlight barriers that defend Xu Tianming's mental sea from spiritual pressure and soul shock. 8 9

• Blocked Kong Deming's escalating mental-pressure test, initially without allowing the assault to penetrate Xu Tianming's body. 8
• Reinforced the barrier and soothed damage when pressure reached the ten-thousand-year soul-ring threshold. 9
• Prepared an enhanced defense that allowed Xu Tianming to withstand the unusually intense soul shock from a resentful ten-thousand-year Magic Flame Wolf. 27 28
• Her protection can be strained by sufficiently powerful mental pressure. 9

Moonlight Perception

Using the Lunar Moment Force and Kuuvahki, Columbina can perceive distant people, soul beasts, and subtle physical actions. 9 33

• Detected a Magic Flame Wolf from roughly one thousand meters away. 9
• States that, at full effort, she can perceive anywhere moonlight reaches, with greater distance consuming more Lunar Moment Force. 9
• Located distressed Ye Guyi approximately eight hundred meters away and sensed unpleasant auras around her pursuers. 14
• Detected deliberate changes in Xuan Ziwen's force while engraving a soul tool array and identified flaws in the resulting sword. 33 36
• Repeated Xuan Ziwen's communication with Jing Hongchen word for word after noticing it. 37

• Soothed damage to Xu Tianming's mental sea after a defensive lapse. 9
• Cooled Ye Guyi during the refinement of Ten-Thousand-Year Whale Glue and helped her safely refine its medicinal power. 25
• Calmed Xu Tianming's heated state during the same incident. 25
• Partially healed decades of hidden injuries within Kong Deming, creating the conditions for his soul-power breakthrough. 26 27
• Cannot yet fully purge all hidden injuries due to insufficient recovered authority. 27

Spatial Authority

Columbina may possess limited spatial authority through the power she inherited from the Three Moons. 26

• Believes she may be able to help Xu Tianming cross or break a god-level spatial array on the night of a full moon. 26
• Her confidence depends on the strength of the array and the incomplete state of her current power. 26

Relationships

• Xu Tianming — Her vessel and symbiotic partner. She recognizes him as the Traveler, protects his mental sea, and gradually accepts him as family; he affectionately calls her “Yaya.” 1 14 20
• Mavuika — A fellow Teyvat entity within Xu Tianming's spiritual sea. Mavuika offers to teach Columbina how family members interact. 1 14
• Ye Guyi — Columbina shows concern for her distress and later uses moonlight to cool and nourish her during whale-glue refinement. 14 25

Trivia

• Columbina's own account attributes her knowledge of the Three Moons' power to having inherited the power and memories of her “sisters.” 1
• She believes the moon's authority can answer questions, though it could not determine what degree of recovered authority would be needed to fully heal all human hidden injuries. 26 27
• Her reason for preventing Ye Guyi from entering an ice bucket was simply that she feared the girl would catch a cold. 25
