Let's Pump Some Iron is a strong acceleration skill with strict and specific trigger conditions. It triggers only when Mejiro Ryan is under the following conditions:
Due to its strict conditions it is known as a gamble skill. Despite that, it is a great inherit for Late Surgers and End Closers who usually maintain 2nd half of the pack positions. When inherited, this skill pairs well with Meijiro Dober's unique skill, Moving Past, and Beyond. However, Meijiro Ryan herself doesn't need the skill in her skill set.
Feel the Burn! is the base version of Let's Pump Some Iron. Its strict trigger conditions are the same albeit with lesser increase to acceleration.

Mejiro Ryan has an A rank on her Late Surger aptitude and has skills like Outer Swell and Rising Dragon that can only actvate with this running style.
To increase the amount of skills you immediately have access to on Mejiro Ryan, it is recommended to max out her Potential level. Getting her to Potential Level 5 unlocks Rising Dragon, a good velocity skill for Late-Surgers. However, if you do not have the Monies or materials to do so, you can obtain Outer Swell instead.
As Mejiro Ryan will be a Medium runner for Team Trials, use a Legacy with Medium sparks to increase its rank from A to S. Do the same for her Late-Surger rank as well to maximize her aptitude.
If you're finding it a challenge to win the Long races in her career, try raising her Long aptitude from B to A using 1 Long spark.
Legacy and Sparks Guide: Inheritance Explained
Mejiro Ryan's hidden event is a Classic Triple Crown race that is easily obtainable as the required races are part of her career goals in the Classic Year (Satsuki Sho, Japanese Derby, and Kikuka Sho). Having a minimum of 400 Stamina is sufficient in clearing these races, especially Kikuka Sho.
Once completed, you are rewarded with +15 to Power and +2 skill hints for Slick Surge.
| 1200 | 800 | 900 | 300 | 400 |
Mejiro Ryan is best assigned as a Medium runner for your Team Trials team, so make sure she has high Speed and Power to help in the late race. Increase her Stamina as well, so she can stay at max speed for longer.
If you are only planning to clear a career run with Mejiro Ryan, then you can aim for lower stat numbers, as the stats above are for Team Trials. However, do note that Mejiro Ryan has four Long races to prepare for in her career, below are the respective Stamina requirements:
For Mejiro Ryan, a deck of 3 Speed, 2 Stamina, and 1 Pal works well to account for the Medium and Long races in her career. She also has a +20% Power growth that could help her reach the Power requirement. Having Riko Kashimoto as a Pal card provides additional Stamina, energy, and Mood increase.
However, if she is lacking on her Power stat, opt for a 3 Speed, 2 Power, 1 Pal setup instead.
This deck is for players who are starting out and are still trying to get a feel of the game's mechanics and intricacies. This deck can help you get the needed stats to clear the career, while also providing important skills.
Take advantage of the game's borrowing feature to borrow a powerful MLB SSR, like Kitasan Black. Additionally, if you do not have an MLB copy of Riko Kashimoto (Tracen Academy), it would be better to use another SR Stamina card instead.
| Recommended Alternative Support Cards | |
|---|---|
| Speed | |
| Stamina | |
| Power |
These cards will help Mejiro Ryan level her needed Stats (especially with Rainbow/Friendship Training), as well as provide some needed skills.
These stats are enough to clear the URA Finale easily, as they provide enough Speed, Stamina, and Power for all of Mejiro Ryan's career races, especially when partnered with the correct skills.
As for the deck, you can run a 4 Speed, 2 Stamina setup to account for the Long and Medium races in her career. You can also go for a 3 Speed and 3 Power deck if she doesn't have enough Power to push through her races.
| Recommended | |
|---|---|
| 9★ Stamina 9★ Power |
|
| 3★ Medium 3★ Late Surger 1★ Long (Optional) |
For Legacy Sparks, we recommend trying to find Stamina and Power sparks with a focus on Stamina. Mejiro Ryan will need it for her career races, especially the Long ones. If needed, try to get at least 1 Long sparks as half of her career races are on Long races to push it from B to A.
For running style sparks, aim for Late Surger sparks to push them up from A to S for a stat bonus.
You can use either your own Veterans, or borrow the ones from your friends. If you do not have Veterans with full sparks, you can go with whatever you have access to.
Since Mejiro Ryan prefers Medium and (potentially) Long races, she will need speed and skills to win her races. On Your Left!, Uma Stan, and Professor of Curvature are great choices to give her the speed she needs.
Since she will also run as a Late-Surger, Rising Dragon is a decent skill that gives her a boost as long as she has someone to overtake on the outside fence on the final corner.
For stamina skills, which is crucial to survive her Long races, give her Swinging Maestro.
For unique skills to inherit, Triumphant Pulse will provide the velocity she needs to put a gap between her and other runners on the final 200m of the race once she moves up to the front of the pack.
If you cannot get the recommended skills, you can replace them with similar skills that you have access to. You will just need to make sure that Mejiro Ryan can activate said skills in a race.

She has something of an inferiority complex surrounding her childhood friend, Mejiro McQueen, and wishes to be as fast and pretty as her. Though physically strong, her heart is rather delicate. | ||

So I won all three classic triple crown races but I did not get the bonus from her hidden event. Why is that?
