Background / History

Anjing Zhen retained the memories and abilities of two lifetimes. Motivated by the possibility of surpassing human limits, he entered the Trainer Academy immediately after middle-school graduation, passed Central Treisen Academy’s Trainer examination after graduating, and moved from his hometown to Tokyo. Although rookie Trainers ordinarily shadow seniors before coaching independently, he chose to proceed on his own, relying on his first-class Extreme Acrobat experience. 1

His parents were consistently patient with his unusually independent and precocious nature. Over time, he came to accept the affection he had not experienced in his previous life, becoming more willing to listen to them and open up emotionally. 16 His childhood materials later revealed a longstanding interest in Horse Girl physiology and training methods. 638

As Kitasan Black’s Trainer, he rejected the harsh special-training regimens associated with his past-world knowledge, believing they were unsafe and exploitative. Instead, he developed safer methods tailored to her exceptional stamina and individual condition. 8

His early tenure was complicated by an Ono Trading Company contract: failure to deliver “ideal results” with Kitasan Black could lead to termination or reassignment. Initially keeping this pressure private, he opened up after she investigated their opponents in an effort to help him. 52

Personality

Anjing Zhen is calm, rational, and highly conscientious. He treats both victories and defeats as information for future improvement; after Kitasan Black’s practice-race loss, he focused on her tangible progress and the lessons gained rather than indulging her disappointment. 89

He is meticulous but can be rigid, especially about plans and stated requirements. When Kitasan Black struggled with specialized material, he recognized that flexibility mattered outside strict training and found a compromise rather than simply enforcing his original rule. 632

His professional reserve conceals intense competitive passion. Extreme Sports bring out a more fervent, almost childlike side of him, and he repeatedly pushes himself to understand the physical experience of the Horse Girls he trains. 118 436 445 This dedication can become self-neglect: jet lag, long work hours, and intensive chase training have left him exhausted or collapsed. 325 501

He gradually becomes more communicative with his team. Rather than merely presenting finished plans, he begins involving them in the planning process and acknowledges his own past avoidance of overseas challenges. 696 697

Abilities & Skills

Training Analysis

Anjing Zhen builds training around individual physical condition, running style, temperament, and psychology rather than relying on standardized drills.

• Identifies physiological limitations through metrics such as heart rate and energy supply, then designs near-limit training intended to improve function without injury. 178
• Treats personality and confidence as factors that directly affect race choices and performance. His assessment of Koushou Hayate linked her missed tactical opportunity to a lack of self-belief. 380
• Adapts plans to differing running styles, including Vodka’s, and organizes joint training that benefits multiple Horse Girls at once. 42
• Uses competitive spirit as a training resource, recognizing it as central to Almond Eye’s performance and to Kitasan Black’s potential to reach the Domain. 287 395

Extreme Skills and WCT Training

He adapts Extreme Acrobat techniques and WCT-style pursuit training into methods that Horse Girls can use in racing.

• Introduced Imaginary Training, including Simulated Lead and Simulated Lag, during joint runs with Kitasan Black, Vodka, and Daiwa Scarlet. 42
• Uses wall running, obstacle movement, center-of-gravity control, coordination, vertical movement, and strength control as training elements. 131
• Developed chase-training concepts into a system intended to improve Kitasan Black’s future racing preparation and position him as her training rival. 424
• Confirmed that Extreme Sports techniques could improve Kitasan Black’s ability to make smaller, more efficient bodily adjustments in short periods. 457
• Personally tested and repeatedly fine-tuned obstacle-course training before having his Horse Girls use it. 444 445

Extreme Acrobatics

Before becoming a Trainer, Anjing Zhen was a professional Extreme Acrobat with first-class abilities. 1

• Demonstrated climbing and acrobatic control by scaling a stone pillar, performing a sequence of movements, and landing precisely at his starting point. 118
• In a Horse Girl Pursuit Battle, evaded Einis Fushin for an entire round through rapid course memorization, equipment-assisted movement, and acrobatics. 421
• Uses obstacles, abrupt direction changes, and circular movement to overcome Horse Girls’ superior raw speed; Almond Eye failed to catch him in a twenty-second chase simulation. 437
• Sees direct participation alongside Horse Girls as a way to gain a more complete coaching perspective. 437

Zone Training

Anjing Zhen devised special training specifically aimed at helping Kitasan Black approach the Zone, a state that allows strength beyond normal limits. He maintains that the Zone does not replace foundational training or regular strength. 141

Research Collaboration

He collaborates with Agnes Tachyon and Daiwa Scarlet on training data and physical-condition research.

• Shared copies of Kitasan Black’s training logs and personal insights with Agnes Tachyon for personal research, with the restriction that she not disclose them to third parties without his permission. 178 186
• Proposed using fluorescent-marker technology to observe Horse Girl condition, prompting Agnes to alter the training-camp plan. 504
• Analyzes training through detailed data, including muscle-fiber vibration frequency, oxygen-concentration changes, and coordination between stride frequency and breathing. 528

Equipment / Weapons / Items

• Tablet and stopwatch — used to record track data, observe runs, and time training. 8
• Drone system — upgraded with thermal imaging to monitor stamina-consumption curves and other training data. 153
• Extreme Skills protective gear — helmet, padded vest, knee pads, elbow pads, and wrist guards used for wall-running training. 131
• Obstacle courses and scaffolding-like structures — assembled for Extreme Skills and chase-training exercises. 444 445
• Pocket watch — a valuable watch bearing a Horse Girl relief symbolizing Eclipse, gifted by Kitasan Black. 357

Relationships

• Kitasan Black — His primary Horse Girl trainee. Their relationship develops from Trainer and trainee into a deeply trusting partnership; she assists with his recovery, studies his methods, and eventually addresses him as “Little Zhen” and “A-Zhen.” 52 255 432 654
• Almond Eye — Assigned Horse Girl and trainee. He recognizes her competitiveness and agility, guides her racing strategy, and uses their chase simulations as both instruction and personal research. 287 368 437
• Agnes Tachyon — Research collaborator and fellow limit-seeker. Though initially wary of her eccentricity, he comes to understand her obsession with speed and shares training insights with her under conditions of confidentiality. 24 178
• Daiwa Scarlet — Training associate who supports his work but challenges him when his expectations of Kitasan Black become too demanding. 42 632
• Tokai Teio — Student Council contact who supports his work through advice, arrangements, and access to race-analysis footage. 24 91
• Symboli Rudolf — Senior ally and professional supporter. She arranged joint training involving Duramente, later expressed confidence in Anjing Zhen during the overseas expedition, and encouraged him to embrace his status as a rookie Trainer. 81 325 348
• Kikou Misuzu — His mother, a warm and teasing former performer known by the debut name “Kikou Misuzu.” 268 633
• Anjing Kouichi — His father, a reserved former Trainer whose support is expressed through actions, including changing careers for the family and offering his old training records to Anjing Zhen’s team. 635 636

Story Role / Major Arcs

Extreme Skills Integration

He reclaims his Extreme Acrobat background as a coaching tool, introducing wall running, obstacle work, pursuit battles, and WCT-based movement concepts. By competing directly in pursuit events, he proves that human technique and planning can challenge Horse Girl speed in specialized environments. 118 131 420 421 424

Team Expansion and Overseas Preparation

As Almond Eye joins his group, Anjing Zhen adapts his methods for multiple trainees and collaborates with Agnes Tachyon and Daiwa Scarlet on data-driven research. His overwork during overseas activities highlights the strain of his growing responsibilities. 271 325 501 528

Shared Leadership and World-Class Ambition

Anjing Zhen increasingly allows Kitasan Black to participate in analysis and mentoring, recognizing the value of Horse Girl-to-Horse Girl communication that he cannot perfectly replicate. He ultimately reveals the team’s goal: to dominate the world-class long-distance circuit. 654 696 697
