Appearance
The Geisha Master is a very short elderly woman with blonde hair tied up with a hairpin. She wears a red kimono with pink lines forming a grid pattern.

Personality
She is strict but supportive teacher towards her students, helping Robin achieve her goal of performing at the Shogun's banquet. Like the majority of Wano Country citizens, she admired the oiran Komurasaki for her beauty and elegance.

Abilities and Powers
She is knowledgeable about the artforms practiced by geisha and was able to teach Robin to perform well enough to be summoned by the Shogun in a rather short period of time.

She is skilled in playing the shamisen, which she uses for perfomances and lessons.

Past
She already had her profession 20 years ago, and performed with other geisha on the night of Kozuki Oden's battle with Kaido.

Wano Country Arc
She took Robin as her student "O-Robi" and trained her in art of geisha, particularly dancing. During the oiran's procession, she appeared to Robin to inform her that she had been summoned by Shogun Orochi. She then explained the concept of "oiran" to Usopp, Sanji and Franky.
