Personality

Xiao Xi's personality is a complex blend of calm composure, deep emotional sensitivity, and a strong protective instinct, all shaped by her mysterious past and divine origins as the human incarnation of the Aeon of Hope, "Xi" 42. She consistently demonstrates a composed and patient demeanor even when facing unknown threats, as seen when she calmly confronted a Heliobus in the Garden of Serenity and showed understanding rather than aggression, seeking a peaceful resolution 72. This patience extends to her interactions with others; she is empathetic and caring, often prioritizing the well‑being of her companions. She shows concern for Dan Heng's situation after escorting Luocha, escorts Bailu to safety when potential dangers arise, and tenderly takes care of a distressed Kaviel, adjusting her coat to shield her from the cold 46 55 61 69. Her protective nature sometimes borders on overprotectiveness—she struggles to trust her teammates fully due to past experiences, feeling the need to shield them perfectly, a tendency Himeko gently helps her address 29. At the same time, Xiao Xi is quick‑thinking and adaptable, able to shift a tense conversation with Lady Yukong by redirecting blame to the Stellaron Hunters, showcasing her resourcefulness and ability to turn a situation in her favor 23. Her curiosity and initiative lead her to join Stelle's ghost‑hunting mission without hesitation, eagerly meeting new squad members and clearing up misunderstandings 71. She is also adventurous, planning trips to explore Aurum Alley and try Xianzhou snacks alongside Stelle, reflecting a willingness to seek relaxation and new experiences 46. However, Xiao Xi carries a heavy emotional burden from her past. She shows rare gloominess upon receiving an invitation written in the language of the destroyed Moon Sky Planet, indicating deep emotional connection and lingering pain 43. When Aha forcibly reveals her memories of separation from the Aeon of Hope, she experiences distress, needing support from March 7th 41. Despite these struggles, she remains thoughtful and reflective, pondering the nature of Aeons and her connection to them with March 7th over tea, and discussing her uncertainty about her divine authority with Welt 22 42. She can be assertive when necessary; she silenced the Aeon Aha during their first encounter in the Simulated Universe, showing she will not be easily overwhelmed 4. She also demonstrates a nurturing side—she reassures Kaviel about belonging on the Astral Express, emphasizes the importance of family, and expresses gratitude toward Himeko for her care 57. Her calm and helpful demeanor extends to strangers, as when she kindly approaches the young Bailu hiding in bushes, trying to understand her situation 46. She also shows signs of fatigue after missions, indicating she recognizes the need for rest and recuperation, with Himeko encouraging self‑care 70. Overall, Xiao Xi is a kind, empathetic, and adaptable individual who grapples with trust issues and the weight of her divine heritage, yet consistently extends warmth, understanding, and protective care to those around her.

Abilities

Hope Blessing

Xiao Xi can bestow a fragment of the Path of Hope upon others, granting them supernatural endurance and purpose. She first demonstrated this ability after revealing the tragic truth of Lily and Rocky’s love story; seeing Rocky’s determination to chase after time to find Lily, Xiao Xi blessed him with the power of [Hope], which allowed him to continue his journey against impossible odds 5. The blessing appears to reinforce a recipient’s resolve and provides a subtle but persistent resilience, enabling them to pursue goals that would otherwise be beyond mortal capability.

• Applications: Strengthens the willpower and determination of the recipient; can be used to aid individuals facing overwhelming emotional or physical trials; acts as a tangible expression of Xiao Xi’s philosophy of spreading hope.
• Limitations: The exact extent and duration of the blessing are unclear; it may require a genuine emotional connection or a worthy cause to be effective; it does not grant direct combat power, only internal fortitude.

Emanator of Hope

As the human incarnation and Emanator of the Aeon of Hope, later revealed to be the Aeon Xi herself, Xiao Xi wields immense Path-based power that manifests as brilliant, purifying flames 1 9. When confronting the Stellaron on Jarilo-VI, which had kept the planet frozen for centuries, Xiao Xi destroyed the artifact with her powerful flames, proving the destructive capacity of her hope-aligned energy 9. She later used her divine power to bring spring back to Jarilo-VI, melting the eternal ice and causing plants to sprout across the surface, demonstrating that her flames can also be used for creation and renewal 11. Xiao Xi discovered her status as an Emanator within the Simulated Universe and began intensive training with Herta to master her Path power, though Herta’s enthusiasm sometimes overwhelmed her 5.

• Applications: Can incinerate Stellaron-level threats; capable of large-scale environmental restoration and terraforming; power scales with her understanding and mastery of the Path of Hope.
• Limitations: Uncontrolled eruptions of Path power can occur under emotional duress, as seen during the Doomsday Beast attack when Xiao Xi’s power erupted involuntarily 3; requires training and focus to wield precisely; overuse may cause fatigue, as she needed rest after the Luofu mission 70.

Authority over Hope’s Power

Xiao Xi has been granted direct authority by the Aeon of Hope—her own divine self—to use Her power and even summon Her at will 22. This authority allows Xiao Xi to act as a proxy for the Aeon, channeling a greater degree of divine energy than a typical Emanator. During the battle against Phantylia on the Luofu Xianzhou, Xiao Xi used a skill to cut off Phantylia’s connection to the Ambrosial Arbor, preventing the Lord Ravager from absorbing its power and enabling the group to capture her 39. This ability appears to interfere with metaphysical links between entities and sources of power.

• Applications: Severing connections between enemies and their power sources; potentially summoning the Aeon of Hope directly; performing actions that require direct divine authority rather than mere Path manipulation.
• Limitations: The full extent of this authority is still being explored; using it may attract the attention of other Aeons, as shown by Aha teleporting Xiao Xi and March 7th after discovering a Light Cone of their battle 40; the burden of wielding such authority contributed to Xiao Xi’s need for rest 70.

Path Energy Eruption

Under extreme stress, Xiao Xi’s Path power can erupt involuntarily in a raw, uncontrolled burst. This occurred on the Herta Space Station when the Doomsday Beast’s gaze triggered an explosive release of her energy, endangering both herself and her companions until Welt stabilized the situation 3. This eruption is tied to her nature as an Aeon’s avatar and may serve as a defensive reflex.

• Applications: Provides a last-resort defensive mechanism when Xiao Xi is overwhelmed; can potentially damage nearby threats.
• Limitations: Uncontrollable and indiscriminate; risks harming allies; requires external intervention (e.g., Welt’s energy manipulation) to stop; leaves Xiao Xi vulnerable afterward.

Locator Crystal

Xiao Xi possesses a locator crystal that she offered to Dan Heng before he left to confront the Vidyadhara High Elder Preceptor, suggesting it can track individuals or be used for teleportation-related assistance 40. While she herself was teleported by Aha, the crystal implies she has some capacity for spatial navigation or coordination.

• Applications: Tracking allies or targets; potentially enabling rapid travel or rescue.
• Limitations: Not fully demonstrated; may require prior placement or activation; Aha’s teleportation was involuntary and not under Xiao Xi’s control.

Sensory Perception

Xiao Xi can sense the presence of spiritual or concealed entities. While alone in the Garden of Serenity on the Luofu Xianzhou, she perceived a presence following her and confronted it, revealing a Heliobus in disguise 72. This ability allows her to detect beings that would normally remain hidden, even from ordinary perception.

• Applications: Detecting invisible or disguised foes; investigating eerie locations; providing early warning against ambushes.
• Limitations: The range and specificity are unknown; may require focus and a calm environment to activate.

Power Progression

• Stage: Ascension to Aeon and Avatar Creation: On the brink of death, Xiao Xi underwent a violent metamorphosis driven by the hope of her people, becoming the Aeon of [Hope]. However, she struggled to retain her humanity and memories during the transition. To preserve her emotions and identity, she created a human avatar, then descended into the universe to spread hope. Years later, this avatar woke up on the Herta Space Station with no memory of her past, carrying powerful Path energy within her 1 2.

• Stage: Initial Awakening and Discovery of Path Energy: Upon waking on the Herta Space Station, Xiao Xi displayed curiosity and adaptability but possessed only a vague sense of the immense Path energy inside her. During the Antimatter Legion attack, Kafka referred to her as a "variable" of destiny, hinting at her latent importance. At this point, Xiao Xi had no control over her abilities and was largely unaware of her true nature 2.

• Stage: Formal Training with Herta: After being recognized as an Emanator of [Hope] by the Aeon in the Simulated Universe, Herta became intensely interested in Xiao Xi's potential and offered to help her master her Path power. Xiao Xi began rigorous training under Herta, who pushed her to develop control and understanding of her abilities. This marked the first structured attempt to harness her power deliberately 5.

• Stage: Granted Authority as the Aeon's Proxy: Later, Xiao Xi revealed that the Aeon of Hope had granted her authority to use Her power and even summon Her at will. An oracle declared Xiao Xi as Her proxy, giving her direct access to the Aeon's strength. This stage greatly increased her practical capabilities, though Xiao Xi expressed uncertainty about the connection 22.

• Stage: Combat Application and Strategic Mastery: During the confrontation with Phantylia, Xiao Xi used a specific skill to cut off Phantylia's connection to the Ambrosial Arbor, preventing her from absorbing its power and securing her defeat. This demonstrated not only raw power but also strategic thinking and refined control, as she effectively neutralized a major threat to the Luofu Xianzhou 39.

• Stage: Unlocking Past Memories and Confirming Identity: Aha, the Aeon of Elation, teleported Xiao Xi and March 7th and revealed Xiao Xi's past memories, showing her separation from the Aeon of Hope. This caused distress but also gave her a deeper understanding of her origins. Subsequently, Xiao Xi received a memory from Fuli, the Aeon of Memory, confirming that she is the human incarnation of the Aeon of Hope, 'Xi'. This stage solidified her identity and provided clarity about her divine nature 40 41 42.

• Stage: Advanced Insight into Divine Conflict and Diplomacy: Following the events on the Luofu, Xiao Xi demonstrated exceptional insight into the Path of Propagation, deducing key aspects of Luocha and Jingliu's plan involving the remains of Tayzzyronth. She also shared her belief in an impending divine war based on information from her Aeon. Her diplomatic skills grew, as she successfully mediated tense confrontations between Jing Yuan, Jingliu, and Luocha, earning respect from both sides 65 66.

• Stage: Emotional and Composure Mastery: Over time, Xiao Xi developed greater emotional intelligence and composure. She showed genuine empathy and concern for Dan Heng's situation, and during an encounter with a Heliobus in the Garden of Serenity, she remained calm, composed, and patient—choosing understanding over confrontation. This stage reflected her growing ability to handle not only her power but also the mental and emotional demands of her role 69 72.

She also confronts a Heliobus in the Garden of Serenity 72, and after the crisis, she returns to the Astral Express to rest while Welt stays behind 69 70.
