TM Opera O Build Guide | Uma Musume Pretty Derby
Written by Priya Kapoor
In Umamusume: Pretty Derby, TM Opera O needs a steady mix of Speed and Stamina to perform well in longer races. Her unique skill is a bit weak, so you’ll need good support cards and reliable inspirations to carry her through.
Here’s how to build her the right way.
Stat Priorities
Speed
Focus on this from the start. Try to hit 150 Speed by debut, and push for 800+ by the end.
Stamina
Aim for at least 600+ if you're entering Long races. Lower is fine if you have recovery skills like Swinging Maestro.
Power
Keep this above 500, maybe even 600+. It helps with turns and keeping up near the end of the race.
Wit
Go for 300 to 350. It helps her recover stamina and use skills more often.
Guts
Not required for most runs. Only include if you're testing a Guts-focused deck.
Best Support Cards for T.M. Opera O
Use a balanced setup that builds Speed and Stamina while keeping her consistent.
3 Speed Cards
Use cards with strong bond gains and useful skill hints. SSRs or good SRs both work.
2 Stamina Cards
Super Creek is a top pick for her recovery skill. A second Stamina card helps round out the stats for Long tracks.
1 Wit Card
Fine Motion is ideal. She helps with skill consistency and keeps your stamina stable during training.
Optional Borrow
Borrow a support with useful skills like Oguri Cap or Tokai Teio. This helps make up for Opera O’s weak personal skill.
Training Strategy
Speed Comes First
Hit 150+ Speed before debut, then keep raising it through midgame.
Build Stamina Gradually
Start training Stamina once Speed is stable. Use Super Creek’s skill to avoid overtraining it.
Use Wit to Avoid Rest
Wit drills give you stamina back and help you keep pace. Use them instead of Rest when possible.
Prioritize Skill Hints
If a useful skill shows up, like Swinging Maestro or Homestretch Haste, take the drill even if it's not Speed.
Check the Race List
Plan ahead and choose races that match her best traits: Long, Turf, and Medium.
Best Skills for T.M. Opera O
Swinging Maestro
Strong recovery skill from Super Creek. Needed for most Long races.
Homestretch Haste
Gives her a good late boost, especially when she falls behind.
Calm in a Crowd, Up-Tempo
Both help with crowded race positions and pacing.
Legacy Skills
Oguri Cap and Tokai Teio provide better unique skills. Use them to improve her coverage.
Race Style Tips
She runs best in Pace or Late style.
Stick to Long or Medium races on Turf. Avoid tracks that don’t match her distance type.
Good legacy picks:
Oguri Cap
Tokai Teio
Silence Suzuka
Avoid Sprint or Front-focused legacies.
Final Blurb
T.M. Opera O needs support to succeed, but she can perform well with the right setup. Her unique skill won’t carry her, so make sure your Speed, Stamina, and borrowed cards do the work instead!
She takes effort, but she’s worth it if you build around her race type.
TLDR
Focus on Speed and Stamina for Long races
Aim for 150+ Speed before debut
Keep Stamina around 600+ unless you have recovery skills
Use 3 Speed, 2 Stamina, 1 Wit for support cards
Super Creek and Fine Motion are the best picks
Borrow Oguri Cap or Tokai Teio for stronger unique skills
Use Wit drills to avoid wasting turns on Rest
Run her as Pace or Late style, not Front
Her unique skill is weak, so your build has to carry the run
