Banba is one of the Amars; her obsession is with all kinds of trains. Banba also has the ability to determine the quality of meat just by looking at it. She can also determine what kind of food is contained within a bag merely by eyeing the package. This is called her Banba Scope. In the English dub, she is voiced by Mariela Ortiz.
Banba is usually phlegmatic and has a dry wit.
Banba's hair is short and very curly. It covers her eyes completely. She usually wears a black and white striped shirt with dark green jeans and blue sneakers.
Banba is friends with all of the Amars, though she seems to be tightest with Mayaya. While everyone is tolerant of the others' obsessions, Banba will willingly participate in hours of engaging in Romance of the Three Kingdoms with Mayaya. When things get tough, both of them go off together to unburden their woes with each other.
