All the hiragana on the pictures are family titles. I can't read Ichirin or Nazrin, and Myouren is conveniently covered. Murasa and Shou are 'Big Sis/Onee-chan.' Kyouko is 'Little Sis/Imouto.' Mamizou and Unzan are Grandma and Grandpa, respectively, or 'Baa-chan and Jii-chan.' (Or Ji-chan, I forget.) And Byakuren is, naturally, 'Mama/Kaa-chan.' And that warms the cockles of my heart.
