Mejiro Ryan Build Guide | Uma Musume Pretty Derby

Training Mejiro Ryan in Uma Musume: Pretty Derby requires careful planning due to her preference for Medium/Long races. Though versatile as a Late-runner or Pace build, improper stat allocation or skill choices can lead to burnout during crucial moments.

Essential Stat Targets

Speed: 900–1000+ (critical for maintaining pace in longer races)
Stamina: ≥500 (or 400+ with healing skills for Long builds)
Power: ≥700 (boosts acceleration and late-race surges)
Wit: ≥400 (ensures consistent skill activation)
Guts: 250+ (supports stamina in Long races unless using recovery skills)

Optimal Support Card Strategies

Balanced Runner Deck

3 Speed | 1 Stamina | 1 Power | 1 Wit
Ideal for mixed race distances with recovery flexibility

Late Skill Specialization

2 Speed | 1 Power | 1 Wit | 1 Friend | 1 Recovery
Prioritizes late-race skills like Slick Surge or Homestretch Haste

Free-to-Play Build

2 Speed | 2 Power | 1 Wit | 1 Stamina
Relies on accessible cards and stable stat progression

Training Key Points

Focus on Speed early, balancing Power/Wit
Acquire recovery skills before major races
Use Recreation over Rest when Wit is high+
Aim for rainbow drills during Summer Camp
Monitor energy levels to prevent burnout

Inheritance Focus

Long A is mandatory for URA success
Include one blue recovery skill + Medium/Long boost skill
Leverage high-spark legacy units for Stamina/Wit bonuses

Race Strategy

Pace builds offer consistency, while Late Surger requires high Wit for reliable triggers. Avoid Front builds entirely due to her poor early-race performance.
