CHARACTER
Pure love in human form. She's so full of love that you can easily tell how lovingly she was raised. Yua is her half-sister (same mother, different father), and while she tries to be friends with her, Yua doesn't seem very willing to open up to her.
She's on better terms with Rui than her sister, and also good friends with her fellow little sister Runa, despite their differing personalities.
Other than her overbearing way of expressing love, she's pure and innocent like a girl her age.
