Meiko Segawa (瀬画和命子, Segawa Meiko) is Akemi's aunt and Shigeru's sister.
Meiko is an extremely eccentric person. She tends to act very hyperactive and girlish, constantly saying that things are "cute" or "adorable". However, her childish personality doesn't take from her artistic genius. She, like most people in her family, is very gifted in the ways of drawing. She and Shigeru are the authors and illustrators of a manga series called Yamato Master (Yamato Masutaa).
