Background
Shizuka kept company with Lord Kiyori over a gap of more than 500 years. When they first met in 1308 in her calendar, she was sixteen and he was fifteen; when they last met in 1311 in her calendar, she was nineteen and he was seventy-nine.
Their last meeting was also the nights they both died.
Appearances
At their last meeting, Shizuka tells Kiyori that the turning points of Shigeru's life have been reached. She does not tell him that one of those points is to murder Kiyori that evening. She does tell him that she will die the next morning although not that she is near to giving birth.
