Onesan

In the world of geisha, the word onesan (pronounced oh-neh-sahn) means 'older sister'. Every maiko (apprentice geisha) has an onesan. When a maiko has her misedashi (formal debut) she goes through san san kudo. San san kudo is a binding ceremony, where a maiko and geiko (geisha) are legally bound as sisters. A maiko's onesan gives her advice and helps her in the complicated world of geisha. A maiko's onesan is always in the same hanamachi (geisha district).

Right now I am only a minarai, but when I have my misedashi, I will be formally bound with my onesan.
