Miko Shibuya is Yuuri's mother. A computer fortune telling program told her that she should be called Jennifer so she sometimes refers to herself as that. She went to Ferris University, which is in Yokohama, so she was often called "Hama no Jennifer"(Jennifer from Yokohama). At university she was in the fencing club and she competed in the Universiade competition. She met Shouma when he was volunteering at the competition. Shouma proposed to her when she was 22 after only having met 5 times. They married half a year later.
Miko seems to always be in an upbeat and cheerful mood as she is easily excited about various things. She also seems to accept things very easily after hearing them like when Shouma told her he was a mazoku and when she heard that Yuuri was engaged to Wolfram.
