If you’ve spent any time in the Uma Musume: Pretty Derby ecosystem, you know the vibe. It is flashy. It is loud. You’ve got Special Week’s relentless optimism and Gold Ship’s... whatever it is Gold Ship does. But then there is Biwa Hayahide. She is the one standing in the corner with the thick glasses and the look of someone who has already calculated exactly how many meters you’ll be trailing behind her at the final corner.
She's different.
Honestly, Biwa Hayahide is a fascinating case of art imitating life. In the game, she is portrayed as this analytical powerhouse, a "cool beauty" who lives and breathes data. But if you think she’s just a boring calculator on legs, you’re missing the point entirely. She is a powerhouse. A literal beast on the track if you build her right. People often overlook her because she doesn't have the "main character" energy of some other girls, but in the competitive meta, ignoring her is a massive mistake.
The Theory of the Big Head: Biwa Hayahide in the Meta
Let’s address the elephant in the room. Or rather, the "large" head. It’s a recurring gag in the Uma Musume anime and game that Biwa Hayahide is sensitive about the size of her head. It’s funny, sure, but it actually masks her true identity as the "Theory Girl."
In the game, her kit is built around high-efficiency racing. She is primarily a Betwixt (Between) or Leader runner. Most players prefer her in the Leader role because it allows her to capitalize on her unique skill, BAM! Bang! (Fortune-Telling Paper). This skill triggers when you're in a good position during the final stages of the race. It’s not just a speed boost; it’s a tactical repositioning.
She isn't a "gamble" character.
If you’re looking for a horse girl who might suddenly explode with a 1-in-100 miracle run, look elsewhere. Biwa Hayahide is about consistency. You want 2nd or 3rd place? She’ll give it to you every single time. You want 1st? You need to back her up with the right support cards, specifically ones that mitigate her stamina drain in Long Distance tracks.

Why the 1993-1994 Era Matters
You can't talk about Biwa Hayahide without talking about her real-life inspiration. This is where the "E-E-A-T" (Experience, Expertise, Authoritativeness, and Trustworthiness) of the character comes from. Cygames didn't just pull her personality out of a hat. The real Biwa Hayahide was a monster on the turf.
She was part of what fans call the "BNW" trio: Biwa Hayahide, Narita Taishin, and Winning Ticket.
In 1993, she was the definition of "always the bridesmaid, never the bride" until she finally broke through. She finished second in the Satsuki Sho and the Tokyo Yushun (the Japanese Derby). It was frustrating. But then she won the Kikuka Sho in record time. That 1993 Kikuka Sho run is legendary. She didn't just win; she dismantled the field. When you play her in Uma Musume, you’re playing that legacy of refined, crushing speed.
Mastering the Training Loop
Training Biwa Hayahide is a bit of a balancing act. You’ve basically got two choices: go all-in on Stamina for the Tenno Sho (Spring) or focus on a hybrid Power/Intelligence build for Mid-distance.
Actually, the Intelligence (Wisdom) stat is her secret weapon.
Because her character is "the smart one," her growth bonuses often lean into Wisdom. In the current Uma Musume meta, Wisdom isn't just about skill activation; it’s about "downhill" efficiency and positioning. A high-Wisdom Biwa Hayahide will rarely get blocked in by other runners. She finds the lane. She stays in the lane. She wins.

- Stamina is the gatekeeper. If you don't hit at least 700-800 Stamina for Long Distance, she will sink like a stone in the final 400 meters.
- Power is the engine. Without at least B+ Power, her "Leader" acceleration won't be enough to pass the early-game "Runners."
- Support Cards: You absolutely need Super Creek (SSR) for "Pure Heart" (Maestro). It’s non-negotiable for her. Without a gold recovery skill, her analytical brain won't save her from burning out.
A lot of people struggle with her "Aries" or "Libra" cup builds because they forget she’s a Stamina hog. She looks like she should be efficient, but her real-life counterpart was a distance specialist. Treat her like a stayer, not a sprinter.
The Siblings Dynamic: Narita Brian
One of the coolest things about Biwa’s storyline is her relationship with her "little sister," Narita Brian. In real life, they were half-brothers. In the game, their rivalry is the stuff of legend.
If you have both characters, the dialogue interactions are gold. Biwa is the over-analytical, protective older sister, while Brian is the raw, untamed talent. This isn't just flavor text. In certain training scenarios, having specific "rival" characters in your deck or as NPCs can trigger secret stat boosts. Biwa gets a lot of these during her Senior Year.
Watch the "Kikuka Sho" event closely. If you win it, the stat gains are massive compared to other girls.
The "Large Head" Misconception
Stop calling it a disadvantage. In the Uma Musume community, the "Big Head" meme is used to describe her hitboxes or her character design, but functionally, it represents her massive Intelligence growth.
Seriously though, some players think her character design is "too busy" or "too stiff." I’d argue the opposite. In a game filled with chaotic energy, Biwa’s stoicism is a breath of fresh air. Her character arc is about learning that logic can’t explain everything—sometimes you just have to run because your heart tells you to. It’s a bit cliché, sure, but the way Cygames handles it through her "Research Notes" events is actually pretty touching.

Practical Strategy for Champions Meeting
If you're taking Biwa Hayahide into the Champions Meeting (the high-stakes PvP mode), you need to be smart.
- Inheritance is Key: Don't just give her random parents. You want to inherit "Red" factors (Distance) to get her Long Distance rating up to S. An A-rank is fine for casual play, but at S-rank, her speed multiplier in the final leg is vastly superior.
- Skill Priority: Look for "Cool Down" or "Arc Maestro." If you're running her as a Leader, "Lightning Step" is surprisingly effective at helping her navigate the pack.
- The Gacha Trap: Her Santa (Xmas) version is actually considered by many to be "sturdier" than her base version for certain tracks. If you have the Christmas Biwa, she’s a monster in Mid-distance.
What Everyone Gets Wrong About Her Skills
Most people see a "Yellow" (Buff) skill and just click it. Don't do that with Biwa.
Her unique skill depends on her being in the top 3 (but not 1st) for a significant portion of the race. If you build her with too much early-game speed, she might jump to 1st place too early, and her unique skill won't trigger until it's too late. It’s a delicate dance. You want her "simmering" right behind the lead runner.
She’s a scalpel, not a sledgehammer.
If you want a sledgehammer, go pull for Oguri Cap. But if you want a runner who rewards you for actually understanding the mechanics of the game, Biwa Hayahide is your girl. There is something deeply satisfying about watching her data-driven approach translate into a 5-length victory over a bunch of "SSS" rank players who didn't bother to check their stamina calculations.
Actionable Next Steps for Biwa Hayahide Fans
To truly maximize Biwa Hayahide, stop focusing on "Speed" as your primary training stat until you’ve secured a solid Stamina foundation. Start by farming Mejiro McQueen or Rice Shower factors to pass down "Stamina" and "Long Distance" traits during the inheritance phase.
Check your support card library for the SSR Yaeno Muteki card; the "Ageless" skill it provides is a perfect match for Biwa’s Leader-style positioning. Finally, run a few practice matches in the "Open" league to see exactly where her unique skill triggers on your favorite track. Tuning her "Intelligence" stat to at least 600 will ensure she activates her recovery skills early enough to survive the final straight.
