"History may be recounted later as one likes, yet I choose to shine in the here and now." She wants to shine bright, no matter how briefly! This well-to-do girl has legs of glass. Mejiro Ardan is a sheltered young lady—ephemeral, gentle, and thoughtful. Despite her fragile, "glass" legs putting her at a disadvantage when running, she refuses to let cynicism keep her down. As a child, her frail body kept her from most recreation and social activities, so she finds community life at the academy to be quite the novel experience.

"Oh, is it time for my race already? Well then, I suppose I shall get ready." Hard determination wins at a slow pace! A lady of leisure. A laid-back and easygoing lady of the Mejiro family. Mejiro Bright’s clumsy side means she does not shoulder the same level of expectation as other members of the estate, but some believe that within the right set of circumstances, she could prove to be one the family's most influential figures.

"You don't need to worry about little old me... Besides, I'm not used to getting so much attention..." She wants to change! This Umamusume bears the scars of her past. While cool and reticent, Mejiro Dober remains tense in many social situations, especially if men are present. Though she was raised in the prestigious Mejiro household, where visitors are never rare, she has nonetheless led a very sheltered life. Perhaps because of this, she can come off cold to strangers, but those who take time to talk to her realize that she is not quite as uptight as she first seems.

"No problems pecs can't solve! Let's get swole together!" Nothing beats a good workout! Even the sweat of her brow is earnest and pure. A sporty girl who loves a good workout. Although born into the prestigious Mejiro family, Mejiro Ryan’s animated personality somewhat betrays that fact. 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.

"I'll bring honor and glory to the Mejiro family!" The crown jewel of the prestigious Mejiro clan. A classy and poised young lady. Born into a family of racing legends, Mejiro McQueen is a long-distance runner who is the envy of her peers. She has class and decorum befitting her prestige, and is determined to take first at the Tenno Sho, like many Mejiro racers before her. On her days off, she enjoys having afternoon tea with the many other residents of the Mejiro estate.
