'Sana is... Well, strange. She refuses to talk under most circumstances and isn't a member of any clubs. All I know is she shares a dorm with Ayane and has a part time job somewhere in the city.'— Sensei's notes
Little is known about her brother except that he worked at the bar before being conscripted into the Space War. She's even wearing his work outfit as means to replace him towards her mother. Apparently she is missing him dearly, fearing for his life. She's avoid the topic, though.
