Mejiro Bright

Mejiro Bright (メジロブライト, Mejiro Buraito) is a character in the Umamusume franchise. She is a student at Tracen Academy.

A laid-back and easygoing lady of the Mejiro family. Her 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.

Bright is an umamusume with wavy long brown hair. Her hair mostly hangs loose except for twin braids done up in front and a prominent ahoge. Bright also has yellow to light brown eyes. She wears a white & turquoise green (the characteristic "Mejiro colors") striped bow and a length of pleated cloth on her right ear. Bright's overall appearance resembles that of a younger Maruzensky.
