Nana Shiratsuki

Nana Shiratsuki (白築 ナナ Shiratsuki Nana) is the sister to Kousuke and the mother of Shino Shiratsuki who is currently missing.

Appearance
Nana has long light blue hair and blue eyes.

Introduction Arc
Nana is first introduced warning Kousuke Shiratsuki not to let Shino Shiratsuki try to eat a mahjong tile. When he says that she won't let go of his finger, she teases him by saying that like herself, Shino cannot tell good men from bad men. A few years later, we see her laying on the couch when Shino comes home. She says that Kousuke had texted her but didn't bother to check it. Later they all play a game of three person mahjong and enjoy themselves. The next day she goes missing.

Idol Arc
Nana is seen making a cameo in Hayari Mizuhara's flashback along with her daughter.

Yue's Arc
It was discovered that Nana use to be a very high class hostess and that she lived in Ginzo before Yokohama. However, every six months, a game of mahjong takes place where she worked, hinting that this may be the cause of her disappearance.

Children's National Tournament Arc
There was a rumor going around that when Niemann visited two years ago, Nana lost in an informal match to a local where the Editor-in-Chief's contacts think that the person who defeated her was Nana. She appeared during the final round of the tournament to watch a bit of Shino Shiratsuki's match and she hands Chiyoko Takahashi a fan letter to give to Shino.

End of Summer Arc
Nana is seen running through a hallway and stops to ask Lotta if she can go outside again because she is hungry, but she is told no and to finish packing.

Shimane Tournament Arc
Nana appears in Shino Shiratsuki's flashback where Nana gives her the important advice of when you don't know what to do, take a step back and look around you. Shino then questions how to do that in mahjong. She says to look beyond the table, observe the mood of the players. Nana then tries to explain it more but mentions there is ice-cream cake in the freezer causing Shino to run off.

Mixed Training Camp Arc
Before sleep, the talk of bed and futons reminded Shino of a conversation with her mother. Nana switches to a bed that is a size bigger because Shino sometimes likes to sleep with her. They then talk about the difference between beds and futons and sleeping habits of people from other countries.

When Shino is asleep she dreams of her mother once again. They were on a trip and Nana tells her about how much she likes traveling to other places but always had a feeling of getting lost. But since Shino was born she has never had that feeling again. She doesn't lose her way because she has it right beside her.
