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.

oneza 

Oneza is a the type of girl you want to be friends with. A girl who likes to have fun in life but not at the cost of her relaxation time. Loves to travel and see the world for what its worth. Her features are exotic and stunning, her smile and laugh light up a room. She can balance being pretty, smarts, and an awesome personality all at the same time. She can be an amazing friend to the people she likes, but the tides can turn easily if she hates you. She is caring, kind, witty, curious, creative and dedicated to helping people. She is good at heart even though she doesn't like to show it to the masses. She is stunning and has a distinct personality which will defiantly liven up your day. She is strong and knows how to give great advice and will be there to listen to all the shit in your life. She tries to make you feel bad about yourself by proclaiming she is mean but deep down you know she loves you. Overall a 10 out of 10.

Damn, that girl is so funny and is super good looking.
That's an Oneza for sure.
