Rejen

Rejen is a Soo-in mercenary who guides Kim Sae-Jin into a hidden Vampire sanctuary and later fights in the coalition organized against Bathory. Her speed, senses, and willingness to exploit an opening make her a valuable covert operative, but the Bathory raid leaves her alive without both arms and dependent on her superior Yu Baek-Song while awaiting treatment.

Biography

Nosferatu alliance and the Bathory conflict

Rejen is introduced as one of two elite Mercenaries selected to guide Sae-Jin on a secret mission into remote mountains. She confidently takes the lead, directs him to the bottom of a sheer cliff, and, when he hesitates, carries him down without outward strain or embarrassment. She then identifies the concealed sanctuary entrance and enters its dark passage ahead of him. When her ears detect an approaching person, she immediately blocks Sae-Jin's progress and challenges the figure. Her actions establish a professional pattern of fulfilling orders through mobility and sensory vigilance while placing herself between her charge and an uncertain threat. (Chapter 124)

Inside the sanctuary, Rejen remains quiet while Sae-Jin negotiates with the Nosferatu representative, allowing him to lead the conversation as requested. Her involuntary ear, nose, and tail movements reveal curiosity and pleasure when tea is offered, briefly showing the person beneath her reserved mercenary manner without disrupting the mission. She later appears within The Monster's secure planning circle and rises with the selected combat team when the anti-Bathory operation begins. These appearances mark a shift from an externally selected guide to a trusted participant in the coalition's most sensitive meetings and operations. (Chapters 125, 135, and 138)

During the confrontation with Bathory, Rejen advances alongside Baek-Song and another fighter when the Vampire begins regenerating. She uses Baek-Song's transformed White Tiger body as cover, emerges beneath it, and drives her blade into Bathory's heart. The coordinated surprise does not kill the target; Bathory recovers quickly enough to slash away Rejen's arms before Baek-Song's follow-up strike lands. Rejen's attack demonstrates courage, timing, and trust in her superior, but its consequence also shows the severe limit of conventional assassination tactics against an opponent able to reorganize Mana and survive a pierced heart. (Chapter 139)

Rejen survives the failed raid and is later found resting with her upper body in Baek-Song's lap while Hazeline prepares access to a potion capable of regenerating her arms. Even while armless, she tells Baek-Song that treatment can wait and tries to smooth over her superior's tactless demand, reversing the expected caretaker role through professional courtesy. Baek-Song refuses and insists that she keep resting. Rejen's latest state is therefore alive but temporarily unable to perform her former scouting and blade work, with regeneration planned rather than yet shown to be complete. (Chapter 142)

Appearance and personality

Rejen is a female Soo-in whose animal ears are initially hidden under a hood. Once uncovered, her ears stand stiff when she detects danger; her nostrils flare at an appealing scent, and her tail sways gently when she enjoys tea. She moves with large, confident strides while guiding outdoors and with light, airy steps inside the sanctuary. The corpus does not identify the exact animal type of her Soo-in features or provide her hair, eye color, height, or clothing beyond the hood. (Chapters 124–125)

Her professional manner is restrained and attentive. She offers Sae-Jin assistance in a worried voice but carries him without changing expression, respects his direction not to interfere in negotiations, and reacts sharply when she senses someone ahead. The small involuntary movements of her ears and tail reveal enthusiasm she does not voice. Her later attempt to defer treatment and protect Baek-Song from awkwardness shows loyalty and self-effacement, though it also leaves her willing to minimize her own serious needs. (Chapters 124–125 and 142)

Traits and abilities

Soo-in mobility and senses

Rejen can descend a precipitous cliff while holding Sae-Jin around the waist, landing well enough that the chapter notes his dizziness and need to brace with Mana rather than any difficulty on her part. She travels with confident, light steps and takes point through unknown terrain. Her ears detect an approaching figure in a dark passage before Sae-Jin reacts, while their erect position and her raised arm show how she translates perception into an immediate protective warning. The source does not name these capabilities as a Trait, quantify her carrying strength, or establish whether her senses exceed those of every Soo-in. (Chapter 124)

Scent and expressive animal features also shape her perception: her nose reacts strongly to aromatic tea, and her ears and tail visibly answer her interest and enjoyment. These responses confirm acute sensory awareness but are not shown functioning over long range, through magical concealment, or amid the chaos of the Bathory battle. After losing both arms, she remains mobile enough to lift her upper body, but the corpus does not show her returning to field duty before regeneration. (Chapters 125 and 142)

Blade combat and coordination

Rejen fights with a blade and uses stealth, positioning, and coordination rather than a prolonged frontal exchange in her only described attack. Moving beneath Baek-Song's White Tiger form conceals her approach long enough to pierce Bathory directly through the heart. The strike lands cleanly while other attacks are being neutralized, demonstrating precise timing and willingness to close with a superior enemy. No named technique, Mana effect, weapon property, or prior combat training is supplied. (Chapter 139)

The same attack establishes her limits and latest condition. A heart wound is insufficient against Bathory's regeneration, and Rejen cannot evade the immediate counterattack that removes her arms. She survives and a regenerative potion is available, but Chapter 142 leaves her still armless and resting in Baek-Song's care. Consequently, the corpus does not establish whether her combat ability is fully restored or how she would compensate if regeneration were delayed. (Chapters 139 and 142)

Power progression

Relationships

• Yu Baek-Song: Baek-Song is Rejen's superior and combat partner. Rejen uses her White Tiger form as cover during the Bathory attack, while Baek-Song later cradles the injured mercenary, demands prompt access to a regenerative potion, and insists that she rest despite Rejen's effort to defer care. (Chapters 139 and 142)
• Kim Sae-Jin: Rejen is selected as one of Sae-Jin's best available guides for a secret approach to the Nosferatu sanctuary. She carries him through the cliff descent, scouts ahead, protects his progress, and respects his control of the negotiation; later inclusion in his covert planning group shows continued operational trust. (Chapters 124–125, 135, and 138)
