Midori Takishima

Midori is the mother of Kei Takishima, and they're very alike. She's always away on business trips, but cares for Kei a lot. When she meets Hikari she wants Hikari to ask a lot of things for her, so she can spoil her like a daughter. Hikari notices that she actually wants Kei to ask things from her but he never did. The chairman of the Takishima company is the father of Midori.
