A waitress at Tae's restaurant, Sanjō Tsubame becomes Yahiko's sweetheart. She was saved by him from the ronin her family worked for, as Yahiko stopped them from robbing the Akabeko. Tsubame is very shy and soft-spoken. When Kenshin enters a living hell after the supposed death of Kamiya Kaoru at the hands of Yukishiro Enishi, Tsubame pleads for Kenshin to help Yahiko fight back against one of Enishi's abandoned allies, bringing Kenshin back into the world of the living. Later, she and Yahiko have a child.
In Seisōhen/Reflection, Tsubame and Yahiko had become a couple, and Watsuki has mentioned in his notes that Tsubame and Yahiko's son is named 'Shinya.' They become a couple in the manga storyline.
