Mejiro Ryan Build Guide | Uma Musume Pretty Derby
Written by Priya Kapoor
In Umamasume: Pretty Derby, Mejiro Ryan gets thrown into more Long races than she really wants, so training her can feel frustrating. She shines as a Medium or Long-distance Late-runner or Pace build, but only if you prep early with recovery skills, Speed focus, and a solid Long inheritance.
She’s a strong finisher, but if you don’t set her up right, she burns out halfway through.
Stat Priorities
Speed
Go for 900–1000 or even a little bit more. She needs Speed to keep up during Medium races and to not get dropped late in Long ones.
Stamina
At least 500+, or around 400 if you bring recovery skills. Aim for more if you're sticking to Long builds.
Power
Target 700+. Helps with her acceleration, especially when running Late or during long straights.
Wit
Get her to 400+. She needs it to keep mood and trigger skills like “Feel the Burn!” reliably.
Guts
250+ is often enough. Useful in Long runs, but don’t overinvest unless you skip healing skills.
Best Support Card Layouts
Balanced Runner Deck
3 Speed, 1 Stamina, 1 Power, 1 Wit
Good for handling Long and Medium events in one route. Includes recovery options and still lets her build key stats.
Late Skill Focus
2 Speed, 1 Power, 1 Wit, 1 Friend, 1 Recovery
If you're going for Late Surger, use cards that give skills like Slick Surge or Homestretch Haste. Use Super Creek or another Stamina card to avoid collapse.
F2P Safety Build
2 Speed, 2 Power, 1 Wit, 1 Stamina
Easy to run with basic cards. Bond growth can be slower, but the stats are safe for Long races if you get a good Legacy.
Training Tips
Prioritize Speed early, but don’t neglect Power or Wit
Train in recovery skills before each G1 if you're not bringing high raw Stamina
Use Recreation instead of Rest if Wit is high and mood is low
Try to unlock rainbow drills by Summer Camp to boost stats late
Rest when needed... she burns out fast if you push too hard
Inheritance Notes
Always get Long A if you plan to run URA seriously
Add one blue recovery skill and either a Medium/Long booster skill
Borrow high-spark legacy girls for Stamina or Wit bonuses
Race Style Options
Ryan works well as Pace in most builds. Late Surger is strong too, but can feel random if you don’t have Wit high enough. If you like consistency, stick with Pace.
Avoid Front entirely. She doesn’t have the tools to dominate early.
Final Blurb
Mejiro Ryan is cool, stylish, and a nightmare to train if you go in blind. If you prep her with recovery, keep her Wit high, and push Speed hard, she can win URA without crashing mid-run.
She doesn’t like being forced into Long races, but if you get Long A and learn a few heals, she stops complaining.

TL;DR
Works best as a Pace or Late-runner in Medium/Long races
Stat goals: Speed 900+, Stamina 500+ (or 400+ with healing), Power 700+, Wit 400+, Guts 250+
Use 3 Speed, 1 Power, 1 Wit, 1 Recovery card for safest coverage
Avoid Front builds completely
Inherit Long A and bring healing or recovery skills
Use Recreation often if mood is yellow or worse
Watch out for energy drain in back-to-back Long races
