She is San’s mother. Unlike her husband Gozaburo, she has more humanlike perceptive. The idea to marry San and Michishio is hers. You may say Ren is controlling her husband and is always trying to stop him of doing anything stupid. Which is not an easy task. She is charming and beautiful in her own way (it is expected from San’s mom). Ren moves to Saitana town with the entire Seto family. There she works as the nurse of Michishio and San’s school.
