Background / History

Mo Shiyu is a member of Chuanbei’s House Mo. Before contracting Xia Yuan, she possessed only Xiao Hei, a C-rank support-type Cat Spirit, despite having the highest spiritual energy among her freshman class. She had also secretly possessed an ability since childhood that lets her view the attributes, potential, and hidden traits of uncontracted spirits. 2

At the Myriad Realms Spirit Card Pool, she used this ability on the fading R-rank Xia Yuan and saw his SSS+MAX growth potential, hidden Many-Faced SSR trait, and full-star contract recommendation. Trusting her assessment, she rushed to contract him just before he disappeared; the contract immediately caused his transformation into an SSR. 2 3 4

Her parents were Lin Yu and Mo Shishan. They died protecting her and other civilians during Ultimate Terror Little Bu’s destruction of Rongcheng City. Mo Shiyu later relived their deaths through a forced return to the past, leaving her emotionally devastated and unable to alter the outcome. 157 After their revenge was achieved, she was finally able to live more freely at Kunlun. 162

Appearance

Mo Shiyu is a tall, slender young woman with fair skin, large clear black-and-white eyes, and delicate features softened by slight baby fat. Her outward aloofness contrasts with an innocent, somewhat dazed charm. 2

• Wears a white, gold-trimmed Spirit Contract Master robe at the academy. 2
• Often has Xiao Hei, a black cat with snow-white wings, resting on her shoulder. 2
• Has been recognized as first on Chuanbei’s campus beauty rankings. 2
• Uses Shinra Bansho’s disguise ability alongside Xia Yuan when moving anonymously at Kunlun. 215
• In ranked matches, Xia Yuan designed her an exclusive “Ahoge King Saber” character model: golden hair in a bun with an ahoge, an indigo battle dress, and mithril shoulder armor. 55

Personality

Mo Shiyu initially appears distant and restrained, but she is quick to make decisive choices when her instincts and appraisal ability tell her an opportunity is real. Her decision to contract a supposedly worthless R-rank spirit came from conviction rather than public opinion. 2

She is conservative about dungeon risks and acutely aware of her own spiritual-power limits, often acting as the practical counterweight to Xia Yuan’s recklessness. Nevertheless, she repeatedly chooses to follow him into increasingly dangerous situations because she trusts his judgment and strength. 7 15 176

Mo Shiyu is proud and highly competitive. When House Mo suggests transferring Xia Yuan to Mo Wushuang because her spiritual power is insufficient, she vows to enter a top Spiritmaster university within a year rather than give up her contract. 12 She pushes herself through grueling secret-realm farming and is willing to endure pain to become strong enough to support Xia Yuan. 128 146

Despite her formal position as Xia Yuan’s contractor, she often indulges his demands and reacts visibly to his teasing. Her attachment to him gradually becomes romantic, though she initially insists they are only Spirit Tamer and spirit. 6 121 236

Abilities & Skills

Spirit Attribute Appraisal

Mo Shiyu can see the attributes, potential, hidden traits, and contract recommendation rating of uncontracted spirits.

• Identified Xia Yuan’s hidden Many-Faced SSR trait and SSS+MAX potential while everyone else saw only an R-rank card. 2
• Her appraisal information directly prompted her to form the contract that saved Xia Yuan from disappearing. 2 3
• The ability is described as something she has possessed since childhood. 2

Spiritual Power Support

As Xia Yuan’s Spirit Tamer, Mo Shiyu provides the spiritual power required for his combat abilities.

• Her limited reserves initially prevent Xia Yuan from maintaining his full power for long periods. 10 11
• Supporting Xia Yuan’s techniques can drain her completely, leaving her unable to stand after combat. 10 20
• She prioritizes spirit stones, breakthrough materials, and inscriptions to improve Xia Yuan rather than drawing additional spirits. 21
• The Holy Grail greatly increases her spiritual power, though the strain of pursuing greater power can be painful. 128 137

Spirit Tamer Barrier

Mo Shiyu can deploy a Spirit Tamer Barrier for defense.

• Held off attacks from three A-class assassin Spirit Tamers, surprising her attackers with the strength of her spiritual power. 31
• Demonstrates that she can resist direct threats rather than relying solely on Xia Yuan. 31

Contract Management

Mo Shiyu directs and cultivates her contracted spirits while organizing their resources and progression.

• Maintains Xia Yuan’s contract despite repeated outside attempts to take him from her. 4 11 20

Contracted Spirits

• Luo Ziyan — Childhood caretaker and friend; the two reunite in the Imperial Capital before the National Spiritmaster Summit Tournament. 71 72
• Mo Cheng — Head of House Mo. He initially seeks to transfer Xia Yuan to Mo Wushuang due to Mo Shiyu’s insufficient spiritual power, but later assists her and Xia Yuan against House Mu. 11 12 206
• Mo Wushuang — House Mo relative who wanted Xia Yuan’s contract and later resents Mo Shiyu for obtaining him. 11 12 217
• Lin Yu — Mother. She died fighting to protect Mo Shiyu and civilians during Little Bu’s attack on Rongcheng. 157
• Mo Shishan — Father. He charged Little Bu despite being unarmed and, after Lin Yu’s death, chose to walk into the flames with her. 157
• Lu Yao — A young member of House Lu whom Mo Shiyu supports when she seeks Xia Yuan’s help to save Lu Changhe. 205

Story Role / Major Arcs

Contracting Xia Yuan

Mo Shiyu enters the card-pool ceremony as a freshman with only a C-rank support spirit. Her appraisal ability reveals Xia Yuan’s concealed value, allowing her to contract him moments before his disappearance and trigger his SSR transformation. 2 3

She defends her new contract when Jiang Li attempts to reclaim Xia Yuan by force. The sudden possession of an SSR makes Mo Shiyu both admired and targeted. 4 9

Early Academy Growth

Mo Shiyu supports Xia Yuan through solo dungeon clears, assassination attempts, and the Abyss dungeon incident. Though frequently exhausted by supplying him with spiritual power, she gains public recognition, an honorary medal, and spirit stones for her contribution to the Abyss-dungeon victory. 7 10 20

When House Mo pressures her to transfer Xia Yuan to Mo Wushuang, she refuses to relinquish him and commits herself to reaching a top university within a year. 11 12

After Xia Yuan’s success in ranked matches, Mo Shiyu travels with him to the Imperial Capital for the National Spiritmaster Summit Tournament. She reunites with Luo Ziyan and acts as the calmer mediator during Xia Yuan and Luo Ziyan’s arguments. 71 72

She later becomes a national champion alongside Xia Yuan, drawing the competing recruitment efforts of Great Xia’s three top Spiritmaster universities. 120

Kunlun University

Little Bu and the Spirit Tamer Great Wall

UR Era and House Mu

After Xia Yuan ascends to UR-level power, Mo Shiyu remains his trusted contractor and a key point of contact with House Mo and the Spirit Tamer Alliance. She is furious over House Mu’s framing of House Lu and follows Xia Yuan’s decision to intervene. 197 205 206
