Midori Nendou(燃堂 緑, ねんどう みどり lit. Nendou Midori) is the mother of Nendou Riki, the wife of Takeuchi Riki, and the ex-wife of Nakanishi Kouta.
Midori has the same appearance as her late deceased husband Nendou and their son Riki with the only difference being the scars on their eyes. Midori divorced Nakanishi so he could stand on his own feet and is currently supporting her son as a single mom.
In a conversation with Kaidou's Mom and Kurumi, Midori revealed how she met Riki's father and gave birth to him when she was just 15 years old.
