Rika's Family

RUMIKO NONAKA/MAKINO
Rumiko is Rika's mother. She's a model and she wants her daughter to follow her steps and become one too. She even drags her to photoshootings sometimes, where Rika needs to wear cute girly clothes she would never want to wear. Rika doesn't want to be a model, that's why they don't get along really well sometimes. Rika's grandmother even warned Rumiko, that family is more important than her job.
When Rika leaves the real world and visits the DigiWorld, she wants to please her mother and she puts the girly dress on. Rumiko is very happy (well, she did drink a bit that time ... xD). After Rika's return home Rumiko realises how much she really misses her daughter. And before Rika leaves home once more, Rumiko gives her the same shirt she already has just the heart on it isn't broken anymore. Rika's really touched by it. Rumiko even bought one for herself too, just the colours are different. She than says to her daugter that she's the same as she was when she was younger. They all said she was too young to get married but she didn't listen to anyone. She was to stubborn, like Rika.

MR. NONAKA/MAKINO
Mr. Nonaka is obviously Rika's father. I don't know what his name is. We meet him in the sixth Digimon movie (The Runaway Digimon Express) but it's just in Rika's memory. Rika goes to her memory, where she sees a swing and a little herself swinging and singing. By the swings is a man. When she calls him 'Dad!', she becomes the one on the swing and the little Rika disappears. Her father is still there, smiling (really scary o.o). Rika says that she hates singing but then she starts to sing. Suddenly she jumps of the swing and takes her father's hand. They walk and she's still singing. And then her father leaves her behind and disappears. Rika then returns to reality. Back at home she thinks about what happened and she seems sad. We see that she also has weaknesses and that she must be really lonely. Rika's father didn't left his family when Rika was younger and she's not wearing the broken heart T-shirt because of him. In Drama CD - Message in the packet Rika says that her father died and as digimontamers resources say that Rika isn't as she is because of her father. His death didn't change her.
However! Rika ALSO says that their parents divorced (episode 47). Was her father alive and died before the Drama CD or is this just a small mistake the producers made? I vote for the mistake! ;P

SEIKO HATA
She's Rika's grandmother. She understands Rika and she sees her as she is, she doesn't want to change her. She's there to link the daughter and the mother, since Rumiko doesn't want to see Rika as she is and pushes the real Rika away. She probaby lives with the family because of the missing father. But the reason why the family was made father-less is because father-less families are really 'popular' in Japan. Well, however, Rika's grandmother believes in Rika and loves her as she is.
