When you first load up the game, learning how to kick an uma starter grass run into high gear is one of the best ways to secure early wins. If you want to successfully kick an uma starter grass campaign, you need to master her dual-strategy running styles and optimize her training schedule.

This comprehensive guide will walk you through her stats, support card configurations, skill selections, and step-by-step training priorities to help you achieve S-Rank.

Understanding Grass Wonder: Base Stats and Growth Rates

Grass Wonder (the 2-star "Stone-Piercing Blue" trainee) is a remarkably balanced character who can comfortably handle multiple distances. Though born in America, her deep love for Japanese culture, sweets, and competitive karuta makes her the spitting image of traditional Japanese elegance. However, do not let her gentle, blue-eyed smile fool you—her determination on the racetrack is unmatched.

To successfully kick an uma starter grass build, you must understand her growth bonuses. She receives a massive 20% bonus to Speed training and a 10% bonus to Power training. This makes her naturally suited for explosive finishes, especially when utilizing her signature Sashi (Pace Chaser) or Oikomi (Late Surger) running styles.

Attribute / Aptitude	Rating / Value	Description & Strategy
Base Rarity	2★ (Stone-Piercing Blue)	Highly accessible starter Kick an Uma.
Speed Growth	+20%	Exceptional bonus; makes hitting the Speed cap easy.
Power Growth	+10%	Great synergy for overtaking opponents in the final stretch.
Turf Aptitude	A	Excellent performance on standard grass tracks.
Dirt Aptitude	G	Avoid dirt tracks entirely; she is strictly a turf specialist.
Mile Aptitude	A	Natural fit for shorter, high-speed races.
Medium Aptitude	B	Easily upgraded to A through Legacy inheritance.
Long Aptitude	A	Strong stamina scaling allows her to tackle long-distance runs.

Stat Allocation and Distance Strategies

Because Grass Wonder has an A rating in both Mile and Long distances, your training focus will change dramatically depending on the role she fills in your Team Trials.

When players try to kick an uma starter grass run, they often make the mistake of ignoring her Medium distance rating. By using Legacy inheritance from parents with Medium distance factors, you can easily bump her B-rank Medium aptitude up to an A, turning her into a truly universal turf racer.

For a Mile build, you can almost entirely ignore Stamina and dump all your energy into Speed and Power. For Medium and Long-distance builds, however, Stamina becomes a hard gatekeeper.

The infamous Arima Kinen race on her calendar requires a hefty chunk of endurance to survive.

Target Stat	Mile Build Target	Medium Build Target	Long Build Target (Arima Kinen focus)
Speed	1100 - 1200 (Cap)	1000+	900+
Stamina	350 - 400	600+	750+ (or 600 with recovery skills)
Power	900+	800+	700+
Guts	300	400	400+
Intelligence (Wit)	400	400	400

Choosing the Perfect Support Cards

Your support card deck is the engine that drives your training sessions. By choosing to kick an uma starter grass campaign with the right support setup, you can easily reach the the final stage.

Because of her natural 20% Speed growth, you do not need a full deck of Speed cards to max out the stat. Instead, a balanced deck of 3 Speed cards, 2 Stamina cards, and 1 Intelligence card is the gold standard for a balanced Long/Medium build. For a pure Mile build, swap the Stamina cards for Power or Guts cards.

According to player experience reports, utilizing top-tier SSR cards with stamina-restoring skills makes her long-distance career runs significantly smoother.

Card Name	Type	Rarity	Why It Is Essential
a support Uma (Piece of Mind)	Stamina	SSR	Provides the "Swinging Maestro" gold recovery skill.
a support Uma (Beautiful Nature)	Intelligence	SSR	Great for boosting Wit and recovering energy during training.
a support Uma (German Precision)	Speed	SR	Excellent budget card that provides valuable skills for Late Surgers.
Fairest Fleur (Grass Wonder)	Guts	SSR	Her own support card; provides excellent training boosts if available.
a support Uma (Nothing Hard Work Can't Solve)	Intelligence	SSR	Offers "Competitive Spirit" to help manipulate pack positioning.

Essential Skills and Strategy Synergies

Grass Wonder excels at Sashi (Pace Chaser) and Oikomi (Late Surger) styles. These strategies keep her in the middle or back of the pack for most of the race, allowing her to save energy before unleashing an explosive burst of speed on the final straightaway.

As you kick an uma starter grass training session, prioritize Speed and Power, but do not neglect her skill point allocation. Her unique skill, Focused Mind, triggers when she overtakes an opponent on the final straight, granting a massive velocity boost.

Pairing this with cornering and recovery skills ensures she has the juice left to make that final, dramatic push.

Skill Name	Type	Effect	Best Strategy Synergy
Focused Mind	Unique	Moderately increases velocity when overtaking toward the back on the final straight.	Pace Chaser / Late Surger
Swinging Maestro	Recovery (Gold)	Significantly restores stamina mid-race on corners.	Long Distance / Medium Distance
Competitive Spirit	Passive	Increases performance when 5+ runners use the same strategy.	Highly flexible; great for adapting to the lobby
Homestretch Haste	Speed	Increases acceleration on the final straightaway.	Pairs perfectly with Focused Mind
Professor of Curvature	Speed (Gold)	Improves positioning and speed on corners.	Keeps her from losing momentum on turns

Step-by-Step Career Training Guide

Successfully navigating Grass Wonder's career mode requires careful planning. You must balance stat training, resting, and racing to hit her specific fan goals and race targets.

Community reports suggest that trying to kick an uma starter grass build without stamina recovery skills is a recipe for disaster in the Arima Kinen.

Below is a year-by-year training breakdown designed to maximize her potential.

Year 1: Junior Season (The Foundation)

Your primary goal in the first year is to build friendship bonds with your support cards. Do not worry too much about specialized stats yet. Focus on training whatever attributes have the most support characters present on the screen to unlock "Friendship Training" (orange bars) as fast as possible.

Aim to complete her Debut race comfortably by maintaining a baseline of 250 Speed and 200 Stamina.

Year 2: Classic Season (The Stamina Test)

This is where her career gets tricky. She will face the Japanese Derby and the Takarazuka Kinen.

To survive the Derby, you will need at least 400 Stamina and a decent chunk of Power to avoid getting boxed in by rival runners. Keep an eye on her mood; always aim to keep her at "Very Good" or "Perfect" to maximize training gains and event choices.

Year 3: Senior Season (The Championship Run)

In her final year, she must conquer the Arima Kinen—a grueling long-distance race. If you have been training her as a Mile or Medium racer, this is where you must rely on gold recovery skills like Swinging Maestro to carry her through.

If she wins the Senior Takarazuka Kinen and her rival Special Week finishes in second place, you will trigger a special easter-egg commentary: "After all, strong Kick an Uma is strong! Though Special Week is strong, the winner is Grass Wonder!"

Training Priority Priority Table:

Junior Year: Friendship Bonding -> Speed/Stamina Balance
Classic Year: Speed -> Power -> Stamina (Target: 400+ Stamina for Derby)
Senior Year: Speed -> Wit -> Maximize Gold Skills

Frequently Asked Questions

What is the best way to kick an uma starter grass run for beginners?

The best way to start is to focus heavily on Speed and Power while utilizing a Legacy parent that boosts her Medium distance aptitude from B to A. Make sure to bring at least one Stamina support card (like SSR a support Uma) to secure a reliable stamina-recovery skill before she faces the long-distance Arima Kinen race.

Is it worth it to kick an uma starter grass build if I have 3-star characters?

Absolutely! Grass Wonder is highly versatile and fits easily into both Mile and Long-distance slots, making her an incredible filler for Team Trials. Because she is a 2-star starter, acquiring her character shards to limit-break her to 3-star and higher is relatively easy, unlocking her full potential without spending premium currency.

What running style is best for Grass Wonder?

While she has an A aptitude for both Pace Chaser (Sashi) and Late Surger (Oikomi), the Pace Chaser style is generally easier to train and has a higher success rate in career mode. It allows her to stay within striking distance of the front runners before triggering her speed skills on the final stretch.

How do I beat the Arima Kinen with Grass Wonder?

To win the Arima Kinen, you need either 600+ raw Stamina or around 450 Stamina paired with at least two solid recovery skills (such as Swinging Maestro or Corner Recovery). If you fail, do not hesitate to use your Alarm Clocks to retry the race and hope for better positioning.
