Tokiko Tsukuyomi  

, 月読 時子

The minister of education resigned shortly after Nasa and Tsukasa got married. She cited concerns about her health and age as reasons for stepping down from politics. Despite her influence and power, she was able to track down Tsukas location while he was still living in Nasas apartment. In chapter 70, when Nasa and Tsukasa went to a hot spring resort, the minister appeared in front of Nasa looking lost because the resort was so large. When Nasa took her back to her own room, Tsukasa revealed his true identity as her grandaunt.
