She seems to have a selfish personality and according to the conversation that her son and Kaai Yuki were having, she has been cheating on Kiyoteru. She then later divorces him which she announced in front of Kaito Hiyama's grave. In episode 8, season 1, Meiko stated that Kiyoteru and Nanami are still husband and wife. It has been hinted that she will make an appearance in Season 2.

In the remake of episode 1, her personality has changed significantly. She became fairly likable compared to her original appearance, not as selfish, and she didn't cheat on her husband.
