Banchina (バンキーナ, Bankīna) was Usopp's mother and Yasopp's wife. She pushed her husband to follow his dreams and go to sea with the Red-Haired Pirates. However Usopp grows up with a sick mother who became bed-ridden due to her illness.

Every day he would tell the same lie, that his father had returned to take them away, hoping it would keep her hopes high and help her to recover. However, she knew he would never return and before her death told Usopp that she was glad he had gone to sea. Even after she passed away, Usopp continued to tell the same lie, even though he no longer had any reason to do so.

In the Loguetown filler Arcs, Yasopp admitted that he was useless and could do nothing for his wife and child. After one of Shanks' men asks "Wasn't it for the better, Yasopp?" Shanks' men hoot and cheer like it was a good thing he left his wife and child.
