Monica Jeffrey

Monica Jeffrey, known as the Sunset Witch, is a Union prodigy whose flame affinity, swordsmanship, and unusually early use of mana agglomeration make her one of humanity's strongest younger heroes. Ranked twenty-seventh when introduced, she combines a loud, irreverent personality with serious loyalty to her teachers, peers, and students. Her career links the Lock's first-year cohort to the Union's war against the Monolith and, later, to the Human-Demon Alliance.

Biography

Union prodigy and interest in the Lock's students

Five years after graduating from the Lock alongside Donna Longbern, Monica has joined the Union and risen far beyond the position her classmate chose as an instructor. She arrives after the Hollberg disaster as Hero Rank 27, suppresses the pressure clash between Donna and George, and interviews Kevin because the Union considers him an exceptional prospect. Kevin refuses her invitation, but his refusal does not end her interest in his development. (Chapters 72–73)

Monica later forces her way into the Lock as a guest lecturer, initially treating procedural training as an annoyance because of her public rank. Once she discovers the quality of Ren's Keiki Style, however, her curiosity becomes sustained instruction. She spars with Ren and Kevin, overwhelms their coordinated strongest attacks without serious difficulty, gives Ren the Quick-slash Style as a visual cover for his hidden art, and judges their growth partly as a reflection of her own competence as a teacher. (Chapters 208, 221–231)

The Monolith operation and a debt to Ren

The Monolith places its highest bounty on Monica because her projected rise to SS rank would materially strengthen humanity. The Union answers an intended ambush with a counter-operation at Monolith headquarters: Monica joins Amon and Tasos, complains about being assigned the weaker S-rank enemies, and then defeats the three Devlon brothers despite their combined formation reaching roughly SS-rank strength. Her confidence is supported by exceptional output, but five minutes of repeated strongest attacks brings her mana and stamina close to exhaustion. (Chapters 269–278)

Tasos's betrayal and Mo Jiahao's arrival turn the operation into a near-disaster. Monica trusts Amon's defense, powers the mana-intensive escape artifact, and waits for the remaining survivors even as her reserves fail. Ren's destruction of the portal core distracts the Monolith long enough for her group to escape; her art-detection sense lets her recognize something familiar beneath his burned face. After learning that the Union abandoned its unknown rescuer, she confronts Daphne and condemns the decision to sacrifice the person who saved her team. (Chapters 278–285)

Issanor reunion and the old academy circle

At Issanor, Monica reunites with Douglas with the unrestrained affection of a former student, then immediately recognizes Ren beneath his altered appearance. She respects Douglas's request not to expose him, disguises her knowledge as teasing, and quietly thanks Ren for saving her at the Monolith. Later, when Donna becomes suspicious of the same disguised man, Monica vouches for him before Donna can press further, using her institutional standing to protect his anonymity without requiring him to reveal himself publicly. (Chapters 384–397)

Her behavior during the reunion reveals the loyalties beneath her irreverence. Douglas remains the teacher whose judgment can stop her mid-charge, Donna remains the friend with whom she can argue without breaking trust, and Ren has changed from an interesting junior into someone to whom she owes her life. Monica's willingness to shield him from Union scrutiny is therefore not casual rule-breaking: it is a deliberate choice to place personal knowledge and earned trust above an institution that had already written him off once. (Chapters 385–397)

Return home and the SS- breakthrough

Back in the human domain, Monica is welcomed into Ren's domestic circle rather than kept at the distance expected of a senior Union hero. She entertains Nola by levitating her around the Dover home and shares the family's relief at Ren's return. When the crack opens in the sky, Monica immediately senses individual psyons thickening in the atmosphere. She draws the denser mana into herself and begins a breakthrough visible across the city, turning a global warning sign into the opportunity that completes years of progress. (Chapters 461–463)

At age thirty-two Monica reaches SS- rank. The advance strengthens her connection to ambient mana and turns her previously imitated agglomeration into a cheaper, denser, and more stable technique. Her first instinct is to test the new output until Donna points out the crowd below, after which she apologizes and helps find a substitute for a mission she can no longer undertake. She later gives Ren a recording implicating Union decision-makers and accepts the personal consequences when he uses it during his press conference. (Chapters 465, 485–488)

Alliance operations and the fall of the Monolith

The later ranking assembly treats Monica's SS- breakthrough as the standard against which Kevin's prospects are measured. Despite the prestige attached to that growth, she continues working in teams formed from her old academy circle. She accepts the Alliance summons, joins the concealed strike planned against the Monolith, and tolerates Donna and Douglas's familiar teasing before the mission. Her humor persists, but it ends the moment the operation begins and she takes her assigned ambush position. (Chapters 608–617, 674, 707–708)

When the Monolith trap is sprung, Monica engages the SS-ranked elder held in reserve while Donna's group attacks the mana compressor. Her orange armor lets her keep fighting and survive the resulting town-leveling blast, but it emerges cracked and her body nearly gives out. She lands beside Donna to confirm the ground team survived and recognizes how close their preparation came to failing. Later, Ren brings Monica with the human domain's strongest rankers into the Demon Domain, preserving her role as a high-tier Alliance combatant after the Monolith falls. (Chapters 708–711, 777)

Wrath and the final defense

During the battles inside the Pillars, Monica helps hold back the main demon forces in Wrath alongside Donna and Douglas. She directs Amanda toward their position after Amanda's mass arrow attack buys time, then candidly admits the danger when a demon prince appears. Monica does not pretend her SS- rank can solve an opponent beyond her tier; she helps the group endure until Ren intervenes and immediately accepts his instruction to stabilize the spatial distortions left by the collapsing pocket world. (Chapters 820–825)

In the final confrontation with Jezebeth, Monica's task is defensive rather than decisive. Amanda calls on her and every other capable fighter to erect barriers against the collision between powers far above the surrounding army. The order fits Monica's established strengths: tangible mana, flight, rapid positioning, and enough judgment to combine her barrier with other rankers rather than treating individual output as sufficient. She survives the war with no later formal advancement recorded beyond SS-. (Chapter 854)

Appearance and personality

Monica has bright dark-orange hair, clear blue eyes, and an unusually small frame, standing about 160 centimeters tall. Her youthful, innocent-looking beauty contrasts with Donna's mature allure and causes people unfamiliar with her to underestimate her age and authority. In combat, orange light gathers around her eyes and body, and her agglomerated armor fits closely over her entire form like a luminous shell. (Chapters 72–73, 276, 373, 707–711)

She is energetic, profane, boastful, intrusive, and easily bored by ceremony. Monica throws devices when a game interrupts her, bribes her way into teaching before completing the Lock's requirements, argues about her height, and openly calls stronger enemies old witches. Compliments embarrass her despite the self-praise, while serious danger strips away the performance quickly. Her comedy is not a lack of judgment; it is the manner in which she lives around responsibilities she understands very well. (Chapters 208, 222–231, 272, 465, 707)

Her strongest personal trait is loyalty expressed without institutional polish. Monica recruits talent for the Union, yet confronts its leadership over Ren, protects his identity, gives him damaging internal evidence, and remains beside former classmates and teachers in later wars. She is candid enough to criticize her employer and practical enough to continue serving humanity through it. That tension makes her neither an obedient functionary nor a purely independent hero. (Chapters 73, 285, 385–397, 485–488, 707–711)

Powers and abilities

Monica is explicitly S+ rank during the Monolith operation and reaches SS- rank when the ambient mana density rises. The advance improves her mana pool, physical force, flight, perception, and control over environmental psyons. It does not make her inexhaustible: her battle with the Devlon brothers drains her within minutes, Mo Jiahao can overwhelm her group, and even her completed armor cracks under the prepared Monolith explosion. (Chapters 276–280, 463–465, 711)

Flame psyons and sword combat

Monica's title comes from both her sunset-colored hair and her unusually high affinity with flame psyons. She can surround movement and sword attacks with orange energy, release beams that scorch their path, and casually break the combined attacks of much weaker students. Her swordsmanship is sufficient for Donna to defer to her as Ren's specialist instructor, and her combat style couples refined blade timing with overwhelming ranged output rather than relying on flame as an uncontrolled area effect. (Chapters 73, 223, 231, 276–278)

Her output has costs and artifact requirements. Repeated strongest techniques exhaust both mana and stamina, and an A-rank sword that amplifies flame control is nearing its tolerance limit while she approaches SS rank. Monica therefore purchases an S-rank replacement at auction for 1.5 billion U. The weapon can channel her stronger output, but the corpus does not provide a unique name or establish a separate artifact ability beyond its rank and suitability. (Chapters 228, 276–280)

Mana agglomeration and orange armor

Before reaching SS rank, Monica can already perform the advanced process called mana or psyon agglomeration: control fine enough to draw tangible mana from the air and shape it into armor. At S+ rank the feat is exceptional but inefficient. The complete orange suit multiplies her offensive and defensive performance, enables sustained aerial combat, and can be projected into attacks or a shield, but damage manifests as cracks and extreme impacts can shatter the surrounding protection. (Chapters 276–280, 532, 619, 711)

At SS- rank her connection to ambient psyons becomes markedly stronger. She can halt visible red particles with a gesture, pull them into a concentrated gauntlet, and release a punch that distorts space and drives a massive beam skyward. The advance reduces mana expenditure while increasing density and stability; it does not remove the need for ambient mana or concentration, and the extraordinary mana-rich conditions around the crack materially assist the breakthrough itself. (Chapters 463–465)

Art detection and perception

Monica possesses a special sense that identifies the art a person practices. It allows her to assess Ren at Hollberg, recognize the familiar discipline beneath a changed or burned face, and pierce identity concealment that would deceive ordinary observers. The sense reads a practiced energy signature rather than supplying every fact about a target: at the Monolith she knows the rescuer feels familiar but needs time and context to connect that signal to someone believed dead. (Chapters 73, 280, 385–397)

Flight, force control, and barriers

Monica can levitate herself, cross space at speeds that appear nearly instantaneous to weaker observers, and manipulate another person gently enough to fly Nola around a room. The same control becomes battlefield mobility and defensive force at higher output. Her agglomerated armor supplies a personal barrier, while the final battle shows her contributing to a larger combined shield. These applications scale with mana and require care: an SS-tier blast can crack her armor, and playful levitation is not evidence of unrestricted telekinesis over resistant peers. (Chapters 252, 276, 385, 461, 711, 854)

Instruction and battlefield judgment

Monica is an effective sword instructor once she accepts the role seriously. She can identify what Ren needs to conceal, choose a related three-and-a-half-star manual, pressure-test coordinated students, and demonstrate the gap between technique knowledge and an S-rank body. In war she accepts target assignments, changes from assault to retreat when betrayal makes the mission untenable, preserves mana for portal activation, and yields impossible opponents to stronger allies. Her judgment is strongest after the joking stops. (Chapters 223–231, 272–280, 820–825)

Power progression

Stage / Realm / AbilityChapter(s)Notes
S rank231Ren explicitly evaluates the gap between himself and Monica as the gap to an S rank while she trains him and Kevin.
S+ rank278Monica is explicitly identified as S+ during the Monolith operation; she already uses an inefficient form of mana agglomeration at this stage.
SS- rank463–465The denser ambient mana around the crack enables her breakthrough at age thirty-two; mana agglomeration becomes more efficient, stable, and powerful.

Relationships

  • Donna Longbern: Donna is Monica's former classmate, closest peer, and recurring comic rival. Monica exceeds her in rank and swordsmanship, while Donna supplies the procedural restraint Monica lacks. They trade insults about age and height, teach the same students, share Ren's confidence, and repeatedly fight in the same Alliance formation. (Chapters 72, 208–231, 373–397, 461–488, 707–711, 820–825)
  • Ren Dover: Monica first reads Ren as an unusually interesting student, then becomes his private sword instructor and supplies an art that helps conceal the Keiki Style. His rescue at the Monolith creates a personal debt she acknowledges at Issanor. She later shields his identity, gives him evidence against Union leaders, and stands with him in the final campaigns. (Chapters 73, 208–231, 278–285, 385–397, 485–488, 777–825)
  • Kevin Voss: Monica attempts to recruit Kevin after Hollberg and later trains him alongside Ren. His rejection does not become hostility; she helps cultivate his swordsmanship and watches him grow into the Alliance leader. By the ranking assembly, his precocious rise is explicitly compared with her own path to SS-. (Chapters 72–73, 231–254, 608, 634, 711)
  • Douglas: Douglas is Monica's former master and a source of moral authority she continues to respect. Her exuberant reunion at Issanor contrasts with the immediate obedience she gives his request to protect Ren's identity. Their easy familiarity survives into the Alliance war, where teacher and student deploy together. (Chapters 319–321, 384–385, 707, 777, 820–825)
  • Emma Roshfield: Emma greets Monica as “Sister Monica” after Hollberg and later encounters her as a Lock guest instructor. Monica belongs to the senior circle watching the cohort's growth, although the corpus gives their bond less sustained attention than Monica's mentorship of Ren and Kevin. (Chapters 73, 221–231)
  • Amon Slabaugh: Amon and Monica bicker before the Monolith mission, then rely on one another when the operation collapses. Monica trusts his shield while she recovers and powers the escape portal; Amon protects her from Tasos and Mo Jiahao long enough for the survivors to withdraw. (Chapters 272–280)
  • Nola Dover: Monica becomes familiar enough with Ren's family to entertain Nola in their home through careful levitation. The scene shows a gentler use of the same mana control she employs in war and places Monica inside the domestic circle Ren most values. (Chapter 461)

Items

  • S-rank sword: Monica wins an S-rank sword at auction for 1.5 billion U after deciding her A-rank flame-amplifying sword will not withstand her power once she reaches SS rank. She uses the new sword while training Ren and Kevin. The supplied corpus does not give it a unique name or a separate confirmed ability. (Chapters 228, 231)
