Kozue Aoba

Kozue Aoba is one of the main characters of Mahoraba. She is the landlady of the Narutaki-Sou and is the love interest of Shiratori Ryushi.

She attends the same high school as Tamami. She has several different personalities that come out when she experiences different emotions, but returns to her original one after sleeping or passing out. Each of her different personalities has a different hairstyle and eye color. Kozue's eye color is a bluish green. She is extremely nice and like all of her other personalities, she enjoys umeboshi. In the manga, she begins going out with Ryūshi in chapter 39. Near the end of the manga, it is revealed that the cause of her different personalities is her sad past where she lost everyone that she loved, starting with the death of her great grandfather and her later abandonment by her parents. It is further revealed that her other personalities were influenced by the 10-year-old Ryūshi who showed her his drawings and taught her that one can be anything in one's imagination. In the epilogue, it is shown that she and Ryūshi are married and have four kids, each of them similar to one of her four alternate personalities.
