Mejiro Dober

Mejiro Dober has long, dark hair with a purple tint.

She often wears an earring on her left ear, showing her motif as a female horse.

Her outfits feature lots of green and white, just like other Mejiro family members, but hers have more white.

Her casual outfit stands out because of large holes on her shoulders, making her look bolder than her shy personality.

Height: 157cm

Three sizes: B83, W57, H81

Shoe size: 22.0cm (both feet)

Mejiro Dober is very polite, just like other Mejiro girls, though she becomes more casual with close friends or people younger than her.

She is very shy and has trouble being in the spotlight, especially after she fell during a childhood race and lost badly.

She really struggles in front of men, sometimes freezing when she hears a man's voice.

Dober lacks confidence in herself—her skills, looks, and personality—but she wants to change and works hard with the help of her friends.

She uses aromatherapy to calm herself and knows a lot about different tea brands.

She hides her love for shojo manga because she feels it's too cute for her.

Dober is a high school student in the Miho dorm.

She grew up as a member of the famous Mejiro family and rarely left their mansion until entering Tracen Academy because of her fear of attention.

Her room in the dorm is shared with Taiki Shuttle, whose lively personality often lifts Dober's spirits.

She feels uneasy being called "Beru-chan" by her father but is okay with her chief trainer using it.

Dober loves small children, and she always tries to talk to them at their eye level.

Mejiro Dober is a powerful runner during practice, showing strong potential.

However, her performance drops in real races when there is an audience.

She has a deep knowledge of tea and aromatherapy.

She is good at drawing and secretly makes her own shojo manga stories.

Her special racing skills are linked to her mid and late-race strategies, with a talent for accelerating when in the right position during a race.

Her nickname is "Dober" or "Beru-chan".

Roommate: Taiki Shuttle

Close friends: Mejiro Bright, Air Groove

She keeps her distance from Mejiro Ryan due to trauma from childhood.

She admires Air Groove for her confidence and poise and often trains with her.

Daiwa Scarlet admires Dober for her coolness.

She is often cheered on by Mejiro family members and has a supportive network, even if she does not always notice it.

"Don’t worry about me… I’m not used to people caring about me like that."

Childhood Trauma and Growth

As a young girl, Dober fell during the start of a race and lost badly.

This made her very anxious, especially in public and around men.

She trained hard at the family estate but rarely went outside until joining Tracen Academy.

Relationships and Teamwork

She acts distant from Mejiro Ryan and prefers the company of the quieter Mejiro Bright.

Her lively roommate Taiki Shuttle often drags her into social activities, helping her open up a little.

She’s close with Air Groove, deeply respecting her strength and kindness.

Overcoming Fears in the Game

In the Umamusume: Pretty Derby game, Dober’s story features her growth as she faces her fears.

Her former chief trainer retires, and the player takes over as her new trainer.

Her story changes a lot depending on the trainer’s gender—she is much more nervous with a male trainer.

As she gains confidence, her interactions become warmer and more open, moving from shy avoidance to a cute “tsundere” attitude.

Racing Achievements

Dober is best at mile and middle-distance races, especially as a “sashi” (closing) runner.

Her special skill, “Beyond That Horizon,” boosts her acceleration if she’s calm and in the middle group during key parts of a race.

She also has a strong reputation for winning many filly (female horse) races, but not mixed races with male horses—this inspired some of her story traits.

Anime and Manga Appearances

Dober appears in several anime seasons and manga adaptations as a member of the Mejiro family.

She sometimes has a stern or cool personality and supports Mejiro McQueen and others.

In the anime, her nervousness around men is not shown strongly, focusing instead on her family relationships.

Special Game Events

In special in-game story events, Dober works hard to build self-confidence, aiming to win the “Best Tiara Umamusume” title by claiming key victories.

Hidden story events are unlocked when she challenges races tied to her racing history, like the Spring Tenno Sho.

Her history is filled with tough goals and unique achievements.

Horse Inspiration—The Real Mejiro Dober

Mejiro Dober’s story is based on a real racehorse born in 1994.

The real Dober was famous for winning top-level races for fillies and never winning mixed-gender races, which is why her character struggles so much with men.

She won 5 Grade I races, setting a record for female horses in Japan.

After racing, she served as a broodmare and later as a “lead horse” caring for younger foals.

As of 2024, she is the oldest living Umamusume model horse, earning respect as “姐さん” (big sister) among fans.

• She is one of the few two-time classic winners among Umamusume girls who didn’t win all three races in the “Tiara Series.”
• Her father is Mejiro Ryan, and her famous siblings include Mejiro Bright.
• Her main trainer in the game is modeled after her real-life stable staff.
• She has a unique reaction based on the player’s gender—a detail that carried over into her voice lines.

• Birthday: May 6
• Weight: No change
• Grade: High school
• Dorm: Miho Dorm
• Specialty: Knows a lot about kinds of tea
• Weaknesses: Men, thunder
• Tail: Uses products that fit her tail’s texture, not just brand names
• Family: Her father feels sad about not being allowed to call her “Beru-chan”
• Rule: Always talk to small kids at their eye level
• Phone wallpaper: A picture with her old chief trainer and new trainer
• Before a race: She looks for her trainer in the stands and makes eye contact

“Just a little bit, I have to move forward step by step.” (Song: Just a Little Bit)
